Pelvic floor disorders are<br />
common in women, <strong>and</strong><br />
as the population ages,<br />
these disorders may be<br />
seen more frequently by health<br />
care providers (Nygaard et al.,<br />
2008). When pelvic symptoms<br />
are associated with loss of structural<br />
support of the pelvic organs<br />
<strong>and</strong> vagina, vaginal support pessaries<br />
offer an important option<br />
<strong>for</strong> relief (American College of<br />
Obstetricians & Gynecologists<br />
[ACOG], 2007).<br />
Historically, vaginal pessaries<br />
have been used to manage pelvic<br />
floor relaxation <strong>and</strong> were made<br />
from a variety of materials,<br />
including fruit, metal, porcelain,<br />

rubber, <strong>and</strong> acrylic (Shah, Sultan,<br />
& Thakar, 2006). Modern pessaries<br />
are made from silicone, acrylic,<br />
latex, or rubber. Flexible, medicalgrade<br />
silicone pessaries are the<br />
primary subject of this article <strong>and</strong><br />
series because they offer many<br />
advantages over other materials.<br />
For example, flexible, medicalgrade<br />
pessaries are pliable, longlasting,<br />
non-absorbent (related to<br />
odor <strong>and</strong> secretions), biologically<br />
inert, non-allergenic, non-carcinogenic,<br />
<strong>and</strong> washable, <strong>and</strong> can generally<br />
be sterilized using an autoclave,<br />
boiling water, or a cold sterilization<br />
product (Cooper Surgical,<br />
2008; Personalmed, 2012).<br />
<strong>Support</strong> pessaries are experiencing<br />
a renaissance <strong>and</strong> are currently<br />
recommended as a first-line,<br />
low-risk treatment option <strong>for</strong> a variety<br />
of prolapse-related symptoms<br />
(ACOG, 2007; Clemons, Aquilar,<br />

<strong>and</strong> related health attitudes;<br />
assess vaginal size, shape, <strong>and</strong><br />

pessaries to women,<br />
including an overview of current<br />

<strong>for</strong> ongoing research.<br />
Pessary <strong>Indications</strong><br />
<strong>Pessaries</strong> are a low-risk option<br />
<strong>for</strong> treatment of pelvic floor disorders<br />
with few absolute contraindications.<br />
Typically, pro viders are<br />
advised to use caution if pessary<br />
c<strong>and</strong>idates have an active vaginal<br />
infection, persisting vaginal erosion<br />
or ulceration, or severe vaginal<br />
atrophy (Weber & Richter,<br />
2005). In addition, non-compliance<br />
with follow up can be problematic<br />
because it may result in<br />
late recognition of complications;<br />
there<strong>for</strong>e, providers are advised to<br />
weigh risks, family support, <strong>and</strong><br />
alternative options carefully<br />
be<strong>for</strong>e providing pessaries to<br />
women with dementia or other<br />
conditions that may lead to irregular<br />
follow up or pessary neglect<br />
(Weber & Richter, 2005). Common<br />
indications <strong>for</strong> the use of support<br />
pessaries include relief of symptoms,<br />
avoidance of surgery, diagnosis<br />
<strong>and</strong> surgical outcome prediction,<br />
<strong>and</strong> prevention (see<br />
Table 1).<br />

Symptom Improvement<br />
Symptoms of pelvic organ<br />
prolapse (POP) may include<br />
pelvic pressure, vaginal bulge,<br />
irritative voiding symptoms, urinary<br />
incontinence (UI), fecal<br />
incontinence, dyspareunia, constipation,<br />
<strong>and</strong> difficulty emptying<br />
both the bladder <strong>and</strong> bowels.<br />
Many trials have reported significant<br />
improvement of common<br />
symptoms, including urinary ur -<br />
gency <strong>and</strong> frequency, <strong>and</strong> urgency<br />
UI; vaginal bulge; pelvic <strong>and</strong><br />
abdominal heaviness <strong>and</strong> pressure;<br />
incomplete or difficult<br />
bowel emptying; flatal incontinence;<br />
<strong>and</strong> fecal urgency <strong>and</strong><br />
incontinence (Barber, Walters,<br />
Cundiff, & the PESSRI Trial<br />
Group, 2006; Clemons, Aguilar,<br />
Tillinghast, Jackson, & Myers,<br />
2004a; Fern<strong>and</strong>o, Thakar, Sultan,<br />
Shah, & Jones, 2006; Komesu et<br />
al., 2007, 2008). Improved bladder<br />
emptying subsequent to reduction<br />
of POP <strong>and</strong> urethral obstruction<br />
may prevent many causes of<br />
ongoing morbidity or mortality,<br />
including recurrent urinary tract<br />
infection, acute urinary retention,<br />
<strong>and</strong> renal injury (Micha et al.,<br />
2008). Both stress <strong>and</strong> mixed<br />
UI were improved with pessary<br />
use in approximately 50% of<br />
women in two separate trials<br />
(Donnelly, Powell-Morgan, Olsen,<br />
& Nygaard, 2004; Richter et al.,<br />
2010). Additionally, overall body<br />
image improves in many successful<br />
pessary users (Patel, Mellen,<br />
O’Sullivan, & LaSala, 2010).<br />
Other areas of symptomrelief<br />
related to pessary use have<br />
been less well studied. For example,<br />
women with a vaginal bulge<br />
can develop epithelial ulceration<br />
due to dryness <strong>and</strong> friction on<br />
clothing. The risk of infection<br />
<strong>and</strong> hemorrhage can be effectively<br />
treated in a plan of careful follow<br />
up <strong>and</strong> pessary use to<br />
enhance healing.<br />
In addition to symptom<br />
improvement, use of support<br />
pessaries can help women meet<br />
their health improvement goals.<br />
In one study, women who<br />
achieved their own pre-determined<br />
treatment goals (improved<br />
bladder control, increased com<strong>for</strong>t<br />
with physical activity, de -<br />
creased prolapse symptoms)<br />
were more likely to be satisfied<br />
<strong>and</strong> continue pessary use as compared<br />
with women who did not<br />
meet their treatment goals<br />
(Komesu et al., 2008). Helping<br />
patients set realistic goals <strong>for</strong><br />
treatment outcomes based on<br />
current evidence will help<br />
women meet their treatment<br />
goals <strong>and</strong> encourage continued<br />
pessary use.<br />
While a majority of women<br />
may note symptom relief with<br />
pessary use, some women cannot<br />
be successfully fitted, <strong>and</strong> others<br />
may experience burdensome<br />
new symptoms during a pessary<br />
trial. New symptoms can include<br />
de novo problems with bowel<br />
<strong>and</strong> bladder emptying, discom<strong>for</strong>t,<br />
pressure, or pain; increases<br />
in vaginal discharge or odor, or<br />
new onset stress UI due to<br />
unkinking of an otherwise inadequately<br />
supported urethra<br />
(Bump, Fantl, & Hurt, 1988). In<br />
one study, the most common risk<br />
factors <strong>for</strong> dissatisfaction related<br />
to pessary use included de novo<br />
stress incontinence, a pre-existing<br />
strong desire <strong>for</strong> surgical<br />
repair, <strong>and</strong> more advanced prolapse<br />
(where the leading edge of<br />
the prolapse is halfway beyond<br />
the hymen or more) (Clemons,<br />
Aguilar, Tillinghast et al., 2004b).<br />
Potential distress may be re -<br />
duced if women considering pessary<br />
use are aware of common<br />
uses, benefits, <strong>and</strong> potential risks<br />
prior to their initial pessary fitting.<br />

Surgical Avoidance or<br />
Scheduling Convenience<br />
Conservative management<br />
with a pessary, either on a temporary<br />
or long-term basis, may be<br />
the optimum choice <strong>for</strong> many<br />
women <strong>for</strong> a variety of reasons.<br />
Although evidence is sparse,<br />
clinical examples of indications<br />
include fear of surgery or anesthesia,<br />
significant co-morbidities<br />
that preclude surgery, or prior<br />
failed surgery with resultant<br />
higher risk of poor surgical outcome.<br />
Temporary use of a support<br />
pessary may improve com<strong>for</strong>t<br />
<strong>for</strong> women delaying surgery<br />
due to career or family priorities,<br />
or <strong>for</strong> women who have been<br />
advised to defer vaginal reconstruction<br />
until child bearing is<br />
completed.<br />
Diagnostic Assessment<br />
And Prediction of Surgical<br />
Outcomes<br />
A pessary trial can provide<br />
an opportunity to explore likely<br />
symptom improvement or the<br />
potential <strong>for</strong> onset of new<br />
adverse effects, <strong>and</strong> help women<br />
develop realistic expectations<br />
during pre-operative treatment<br />
planning. In a classic study,<br />
researchers used a trial with a<br />
lever pessary to successfully<br />
predict surgical cure of stress<br />
incontinence via retropubic urethropexy.<br />
In this trial, 24 of 26<br />
women with stress UI became<br />
continent with a supine stress<br />
test after pessary insertion, <strong>and</strong><br />
all patients remained continent<br />
after a retropubic urethropexy<br />
was per<strong>for</strong>med (Bhatia &<br />
Bergman, 1985). In another<br />
study, de novo stress incontinence,<br />
which can occur when an<br />
otherwise deficient urethra is<br />
straightened during repair of the<br />
prolapsed anterior compartment,<br />
was shown to be a major<br />
reason <strong>for</strong> post-treatment dissatisfaction<br />
(Clemons, Aguilar,<br />
Tillinghast et al., 2004a).<br />
Post-surgical expectations<br />
have also been explored with<br />
women reporting two common<br />
symptoms often attributed to<br />
POP – lower abdominal pressure<br />
<strong>and</strong> low back pain (Heit,<br />
Culligan, Rosenquist, & Shott,<br />
2002). In that study, participantrated<br />
symptom severity using<br />
visual analog scales, (n = 152)<br />
was compared with objective<br />
prolapse determination <strong>and</strong><br />
demonstrated no significant<br />
association. There<strong>for</strong>e, because<br />
prolapse may not be the cause of<br />
some symptoms, a pessary trial<br />
can play a role in clarifying<br />
treatment expectations during<br />
pre-operative decision-making.<br />
<strong>Pessaries</strong> have also been<br />
useful in predicting successful<br />
outcomes in cases of pre-operative<br />
elevated post-void residual<br />
(PVR) due to urethral obstruction.<br />
A retrospective chart<br />
review of women with pre-operative<br />
PVR greater than 100 cc (n<br />
= 24) found that pessary use normalized<br />
PVR in 75% (n = 19) of<br />
the women, with only one<br />
woman subsequently experiencing<br />
elevated PVR three months<br />
post-operatively. A trial pessary<br />
reduction was found to be a reliable<br />
tool in predicting improvement<br />
in urinary retention<br />
(Lazarou, Scotti, Mikhail, Zhou,<br />
& Powers, 2004).<br />
Prevention of Progressive<br />
Prolapse<br />
Emerging evidence also suggests<br />
a potential preventive role<br />
<strong>for</strong> pessaries. H<strong>and</strong>a <strong>and</strong> Jones<br />
(2002) observed a significant<br />
improvement in stage of POP in<br />
19 women following one year of<br />
successful pessary use, suggesting<br />
a therapeutic effect associated<br />
with the use of a supportive<br />
pessary. In addition, in an observational<br />
cohort study of women<br />
using pessaries <strong>for</strong> three months<br />
(n = 90), measurement of the genital<br />
hiatus decreased, leading the<br />
authors to postulate that pessary<br />
use allows recovery of the levator<br />
ani muscles (Jones et al., 2008).<br />
In another small case series (n =<br />
6), prolapse regressed to normal<br />
after a median duration of pessary<br />
use of 27.5 months <strong>and</strong><br />
remained resolved <strong>for</strong> a median<br />
of 42.0 months of follow up<br />
(Matsubara & Ohki, 2010).<br />
Whether this observed prolapse<br />
improvement is due to temporary<br />
physiologic tissue response to<br />
reduced strain <strong>and</strong>/or has potential<br />
long-term preventive ramifications<br />
is currently unclear.<br />
Pessary Selection<br />
Modern silicone pessaries<br />
come in a variety of shapes <strong>and</strong><br />
sizes; there<strong>for</strong>e, selection is primarily<br />
determined by the<br />
lifestyle of the potential wearer,<br />
as well as findings on physical<br />
examination. Both providers <strong>and</strong><br />
patients are likely to benefit if<br />
pessary success could be predicted<br />
because counseling would be<br />
improved, time would be saved,<br />
<strong>and</strong> needless discom<strong>for</strong>t would<br />
be eliminated; however, predictive<br />
parameters <strong>for</strong> pessary<br />
choice <strong>and</strong> fitting success have<br />
proven difficult to quantify<br />
(Cundiff et al., 2007). For that<br />
reason, expert opinion from clinical<br />
observation continues to<br />
in<strong>for</strong>m both patient <strong>and</strong> pessary<br />
selection <strong>and</strong> is included here <strong>for</strong><br />
the potential benefit of novice<br />
providers.<br />
Patient-Specific Factors<br />
Several recent studies concluded<br />
that the majority of<br />
women can be successfully fitted<br />
with a pessary, with POP-reduction<br />
success rates ranging from<br />
63% to 86% (Clemons, Aguilar,<br />
Tillinghast et al., 2004b; Hanson,<br />
Schulz, Flood, Cooley, & Tam,<br />
2006; Maito, Quam, Craig,<br />
Danner, & Rogers, 2006; Mutone,<br />
Terry, Hale, & Benson, 2005;<br />
Nyguyen & Jones, 2005; Wu,<br />
Farrell, Baskett, & Flowerdew,<br />
1997). However, specific factors<br />
that might predict successful fitting<br />
have not been consistently<br />
identified. Some studies have<br />
suggested that patient satisfaction<br />
is higher in women who are<br />
older, have had no prior pelvic<br />
surgery (including hysterectomy),<br />
have higher parity or less<br />
severe prolapse, <strong>and</strong> have no UI<br />
116 UROLOGIC NURSING / May-June 2012 / Volume 32 Number 3
SERIES<br />
(Maito et al., 2006; Nyguyen &<br />
Jones, 2005; Wu et al., 1997).<br />
Hanson et al. (2006) assessed the<br />
importance of estrogen therapy<br />
to successful pessary fitting,<br />
reporting that women using vaginal<br />
estrogen, with or without systemic<br />
hormone replacement therapy<br />
(HRT), had higher fitting success<br />
compared to both systemiconly<br />
<strong>and</strong> non-HRT users. Maito<br />
et al. (2006) reported presence of<br />
mild posterior compartment prolapse<br />
as a positive predictor of<br />
fitting success, <strong>and</strong> history of a<br />
prior prolapse procedure or hysterectomy<br />
as negative predictors.<br />
Clemons, Aguilar, Tillinghast et<br />
al. (2004b) also found a shortened<br />
vaginal length (≤ 6 cm) <strong>and</strong><br />
wide genital hiatus (4 fingerbreadths)<br />
to be predictive of<br />
unsuccessful pessary fitting.<br />
Other researchers have reported<br />
no significant predictive value<br />
regarding age, weight, vaginal<br />
length, size of genital hiatus,<br />
compartment of prolapse, stage<br />
of prolapse, or hormone use<br />
(Maito et al., 2006; Mutone et al.,<br />
2005; Nyguyen & Jones, 2005;<br />
Wu et al., 1997). Because of this<br />
lack of consistent predictors, a<br />
pessary trial may be appropriate<br />
<strong>for</strong> any woman seeking treatment<br />
<strong>for</strong> prolapse-related symptoms<br />
(ACOG, 2007; Clemons, Aguilar,<br />
Sokol et al., 2004).<br />
Factors related to patient<br />
preference, lifestyle, <strong>and</strong> ability<br />
may guide pessary choice. For<br />
example, some pessaries may be<br />
easier to self-remove <strong>and</strong> selfinsert.<br />
This may affect choice<br />
related to patient com<strong>for</strong>t with<br />
self-touch, interest in per<strong>for</strong>ming<br />
self-care, <strong>and</strong> desire to have vaginal<br />
intercourse. Clinical experience<br />
suggests that arthritis,<br />
mobility impairment, <strong>and</strong> obesity<br />
may limit successful self-care,<br />
even in very motivated women.<br />
Women who are not doing selfcare<br />
will need to wear their pessary<br />
continuously between the<br />
periodic office visits <strong>for</strong> removal<br />
<strong>and</strong> cleaning.<br />
With the appropriate pessary,<br />
a sexually active woman has a few<br />
options. The pessary can be re -<br />
moved <strong>for</strong> intercourse either by<br />
the woman or her partner. If she<br />
prefers leaving the pessary in<br />
place, some styles (<strong>for</strong> example,<br />
Ring pessaries) are more likely to<br />
be com<strong>for</strong>table <strong>for</strong> both partners<br />
during intercourse. However,<br />
there is little research to assess this<br />
specifically, <strong>and</strong> clinical reports<br />
from individual couples vary<br />
greatly. Overall, sexual function<br />
has been shown to improve with<br />
pessary use, including frequency<br />
<strong>and</strong> satisfaction (Fern<strong>and</strong>o et al.,<br />
2006), desire, orgasm, <strong>and</strong> lubrication<br />
(Kuhn, Bapst, Stadlmayr, Vits,<br />
& Mueller, 2009). Additionally,<br />
one study found sexually active<br />
women were more likely to continue<br />
pessary use compared to<br />
women who were not sexually<br />
active (Brincat, Kenton, Fitzgerald,<br />
& Brubaker, 2004). Overall, pessary<br />
use may be acceptable to<br />
many sexually active women.<br />
Pessary-Related Factors<br />
Many pessary styles <strong>and</strong><br />
sizes are available, <strong>and</strong> new<br />
styles continue to be designed.<br />
Figure 1 displays a variety of current<br />
pessaries. While successfully<br />
fitted pessaries offer a high<br />
Figure 1.<br />
Pessary Shapes<br />
Note: The large variety of pessary shapes can be categorized as pessaries that<br />
require significant introital support (top row), pessaries that are relatively selfsupporting<br />
(seond row), <strong>and</strong> pessaries with an incontinence support (third row).<br />
likelihood of symptom <strong>and</strong> quality-of-life<br />
improvement <strong>for</strong> most<br />
users, no specific shape of pessary<br />
is best <strong>for</strong> all women. In one<br />
crossover study comparing two<br />
different pessaries (Ring <strong>and</strong><br />
Gellhorn), both shapes were<br />
effective <strong>for</strong> the majority of<br />
women <strong>and</strong> significantly im -<br />
proved urinary, bowel, <strong>and</strong> prolapse<br />
symptoms (n = 134, mean<br />
age 61 years, median prolapse<br />
Stage 3 – descent halfway<br />
beyond the hymen, satisfaction<br />
rates – Ring 80%, Gellhorn 76%)<br />
(Cundiff et al., 2007).<br />
Because no quantitative mea -<br />
sures have been identified to<br />
direct pessary choice <strong>and</strong> fitting,<br />
providers must continue to rely<br />
on manufacturer guidelines,<br />
expert opinion, product availability,<br />
clinical judgment, <strong>and</strong><br />
provider or patient preferences<br />
when choosing initial pessary<br />
shape <strong>and</strong> style.<br />
One way to conceptualize<br />
support pessary options is to categorize<br />
them by their functional<br />
design. Using that paradigm,<br />
flexible silicone pessaries fall<br />
into three categories: those that<br />
need some support from the<br />
woman’s own introital integrity<br />

to stay in place (basic support pessaries), pessaries<br />
with concavities that make them relatively selfretaining<br />
(self-retaining pessaries), <strong>and</strong> pessaries<br />
with additional urethral support designed to<br />
improve stress incontinence (incontinence pessaries).<br />
<strong>Use</strong> of these classifications to guide initial<br />
choice is summarized in Table 2.<br />
In the authors’ experience, pessaries retained by<br />
introital integrity can be folded or deflated to ease<br />
insertion through the introitus. Examples include<br />
the Ring (see Figure 2), Donut (see Figure 3), <strong>and</strong><br />
Inflatable Donut (see Figure 4), <strong>and</strong> the Shaatz <strong>and</strong><br />
lever pessaries (not pictured separately). Those that<br />
have a relatively slim profile <strong>and</strong> fit along the length<br />
of the vaginal shaft, such as the Ring pessary, are<br />
most likely to be com<strong>for</strong>table when left in place during<br />
vaginal intercourse. Others, such as Donut pessaries,<br />
which are sometimes referred to as space-filling<br />
pessaries because they occupy more of the vaginal<br />
width, may preclude intercourse when in situ.<br />
<strong>Pessaries</strong> designed to easily fold or deflate may also<br />
be most amenable to self-insertion <strong>and</strong> removal.<br />
In contrast, self-retaining pessaries are generally<br />
concave in shape. The vaginal walls con<strong>for</strong>m to<br />
these areas, allowing the pessaries to stay in place in<br />
women with minimal or no introital strength. These<br />
include the Gellhorn (see Figure 5) <strong>and</strong> Cube pessaries<br />
(see Figure 6). These are traditionally considered<br />
more likely to support advanced POP but may<br />
also increase the risk of mechanical injury to the<br />
vaginal epithelium. They may also be more difficult<br />
<strong>for</strong> both the patient <strong>and</strong> provider to remove <strong>and</strong> reinsert.<br />
Incont inence pessaries include a knob that fits<br />
behind the pubic symphysis, supporting the urethra<br />
during times of increased abdominal pressure to<br />
diminish stress incontinence (see Figure 7).<br />
Although the topic is not well studied, when a<br />
pessary is worn over time (longer than 24 hours),<br />

presence of drainage holes should<br />
allow continuous drainage of normal<br />
vaginal epithelial shedding<br />
<strong>and</strong> discharge. Retained discharge<br />
may act as a medium <strong>for</strong> bacterial<br />
overgrowth, increasing infection<br />
risk, <strong>and</strong>/or odor. For this reason,<br />
pessary styles with optional<br />
drainage holes (such as Cube pessaries)<br />
are typically preferred<br />
whenever possible.<br />
Providers often prefer to use a<br />
limited selection of available pessaries.<br />
For example, in a survey of<br />
urogynecologists, the majority<br />
reported using Ring pessaries <strong>for</strong><br />
anterior <strong>and</strong> apical defects, spacefilling<br />
pessaries (such as a Donut)<br />
<strong>for</strong> women who have introital<br />
integrity <strong>and</strong> posterior defects, <strong>and</strong><br />
self-retaining pessaries (such as the<br />
Gellhorn) <strong>for</strong> severe prolapse<br />
(Cundiff, Weidner, Visco, Bump, &<br />
Addison, 2000). General gynecologists<br />
reportedly also used Ring pessaries<br />
most frequently, deeming<br />
them easiest to use, with Gellhorn<br />
pessaries used most commonly <strong>for</strong><br />
advanced prolapse (Pott-Grinstein<br />
& Newcomer, 2001). The latter<br />
respondents rated Donut pessaries<br />
the least easy to wear <strong>and</strong> Gellhorn<br />
pessaries most difficult to remove.<br />
Generally, providers’ choice of<br />
styles of pessary to stock <strong>and</strong> fit<br />
appears to be based on the individual’s<br />
training, experience, <strong>and</strong><br />
product availability.<br />
Pessary size selection is also<br />
currently guided by experience<br />
because no specific vaginal measures<br />
have predicted successful fit.<br />
In one study, Pelvic Organ<br />
Prolapse Quantification (POP-Q),<br />
parameters were tested as a potential<br />
objective predictor but were<br />
not found to predict pessary size;<br />
however, women with a shorter<br />
total vaginal length were less likely<br />
to be successfully fitted (Nager<br />
et al., 2009). Thus, pessary fitting<br />
remains an art, with some reliance<br />
on trial <strong>and</strong> error.<br />
Pessary <strong>Fitting</strong><br />
Because there has been little<br />
success in identifying objective<br />
evidence to improve pessary<br />
choice, new providers must rely<br />
on expert opinion <strong>and</strong> mentorship.<br />
Pessary manufacturers provide<br />
recommendations to help the<br />
novice match pessary styles with<br />
patient findings (Bioteque of<br />
America, 2011). Successful fitting<br />
also depends on clinician experience<br />
<strong>and</strong> training. Few nursing or<br />
medical programs spend time<br />
teaching pessary use (Pott-<br />
Grinstein & Newcomer, 2001).<br />
However, with a sound general<br />
background of women’s health<br />
care, even in the absence of optimal<br />
mentorship, clinicians can<br />
educate themselves to become<br />
competent <strong>and</strong> safe providers of<br />
this low-risk intervention.<br />
The goal of fitting is to find a<br />
pessary that improves the target<br />
pelvic floor symptoms, is com<strong>for</strong>table<br />
<strong>for</strong> the patient, is retained<br />
during activity <strong>and</strong> toileting, <strong>and</strong><br />
does not obstruct voiding or defecation,<br />
or cause vaginal irritation.<br />
Suggestions <strong>for</strong> improving fitting<br />
outcomes are listed in Table 3.<br />

Table 3.<br />
Pessary Selection <strong>and</strong> <strong>Fitting</strong> Tips<br />
Assess <strong>for</strong> <strong>and</strong> treat causes of vaginal tenderness prior to fitting (infection, lesions,<br />
or tension myalgia).<br />
Familiarize the woman with the pessary be<strong>for</strong>e fitting (let her see, feel, <strong>and</strong> fold it; use<br />
visual aids, such as pelvic models or charts, to show how it will stay in her vagina).<br />
<strong>Fitting</strong> will be more com<strong>for</strong>table if the woman has an empty bladder <strong>and</strong> bowel;<br />
however, to test <strong>for</strong> stress incontinence, fitting with the bladder full will facilitate<br />
assessment. If the bowel is full <strong>and</strong> cannot be emptied voluntarily, an enema onsite<br />
or rescheduling the appointment may be most helpful.<br />
Autoclavable fitting kits are available, but keeping a small stock of silicone pessaries<br />
in commonly used sizes <strong>and</strong> shapes may offer a more true-to-life fitting experience.<br />
<strong>Fitting</strong> com<strong>for</strong>t may be improved <strong>for</strong> women who are very apprehensive or sensitive<br />
by the use of lidocaine gel applied to the introitus 5 minutes be<strong>for</strong>e fitting. If genital<br />
tissue is very atrophic or non-elastic, several weeks of topical estrogen therapy prior<br />
to fitting may be optimal.<br />
Refitting may be necessary after weight loss or weight gain, any period of temporary<br />
removal, or during long-term use if atrophic tissue change continues (increased<br />
stenosis or decreased support).<br />
During post-fitting pessary testing, placement of a urine receptacle (“Hat”) in the<br />
commode will ease retrieval if the pessary is expelled. Otherwise, instruct the woman<br />
not to flush the pessary into the plumbing system.<br />
A pessary that is com<strong>for</strong>table <strong>and</strong> retained except during bowel movements may be<br />
a success if the woman chooses to either remove the pessary <strong>for</strong> defecation or<br />
support it digitally during evacuation.<br />
If the pessary is easily expelled, try a larger size or different style. If the pessary is<br />
uncom<strong>for</strong>table or the patient feels pressure, try a smaller size or different style.<br />
Successfully sized, the pessary should be com<strong>for</strong>table; women often say, “I can’t<br />
even tell it’s there!”<br />
Make sure a system is in place to identify missed pessary follow-up visits to avoid<br />
potential problems related to pessary neglect.<br />
Figure 8.<br />
Illustration of Digital Measurement of the Vagina, a Potential Aid to<br />
Initial Pessary Choice<br />
Notes: Line A: The vaginal length from posterior symphysis to apex or posterior<br />
<strong>for</strong>nix can be useful <strong>for</strong> sizing Ring <strong>and</strong> Donut pessaries, or the length of a Gellhorn<br />
neck. Line B: The vaginal width at the apex can be useful when considering the<br />
diameter of the Gellhorn dish. Line C: The diameter of the introitus <strong>and</strong> vaginal shaft<br />
can help in making an initial Cube choice.<br />
Although definitive measurements<br />
have not been identified to<br />
aid size <strong>and</strong> style choice, experienced<br />
providers typically note<br />
several digital measurements <strong>and</strong><br />
assess pelvic muscle tone <strong>and</strong><br />
support during pelvic examination<br />
(see Figure 8). These determinations<br />
can help the provider<br />
develop a mental image of the<br />
vaginal size, shape, <strong>and</strong> support.<br />
The initial pessary attempt can<br />
then be made using the pessary<br />
that fits this visual image. Table 4<br />
lists suggested steps in pessary fitting<br />
based on clinical experience<br />
<strong>and</strong> expert opinion.<br />
The average number of pessaries<br />
tried during a successful<br />
pessary fitting is two to three, typically<br />
at a single session; however,<br />
up to two follow-up fitting sessions<br />
have been reported prior to<br />
successful fitting (Jones et al.,<br />
2008; Komesu et al., 2007; Maito<br />
et al., 2006; Robert & Mainprize,<br />
2002; Wu et al., 1997). Women<br />
unable to retain a pessary at an<br />
initial fitting are less likely to be<br />
successful at subsequent fittings<br />
(Maito et al., 2006), but persistence<br />
may pay off. Clemons,<br />
Aguilar, Tillinghast et al. (2004b)<br />
found 22 of 49 women who could<br />
not be fit at the first visit were successfully<br />
fit on the second visit. In<br />
that study, a Gellhorn pessary was<br />
more likely to require refitting<br />
than a Ring, suggesting Ring pessaries<br />
are easier <strong>for</strong> providers to<br />
size correctly. For women who prefer<br />
pessary treatment but have difficulty<br />
retaining any single pessary,<br />
occasional use of double pessaries,<br />
including a Donut with Gellhorn<br />
or double Ring, has been reported<br />
(Myers, LaSala, & Murphy, 1998;<br />
Singh & Reid, 2002).<br />
Prior to fitting, women should<br />
be in<strong>for</strong>med that the risk of a pessary<br />
trial is minimal, while the<br />
potential symptom-relief can be<br />
great. It may be helpful to be optimistic,<br />
normalizing the fitting situation,<br />
while in<strong>for</strong>ming the woman<br />
prior to fitting that an appropriate<br />
pessary may not be identified.<br />
Clinicians also need to remember<br />
that successful fitting after three or<br />
120 UROLOGIC NURSING / May-June 2012 / Volume 32 Number 3
SERIES<br />
four attempts is less likely. To aid<br />
underst<strong>and</strong>ing of current pessary<br />
choices, the following sections<br />
look more specifically at commonly<br />
used pessary options.<br />
Table 4.<br />
Steps to Pessary <strong>Fitting</strong><br />
1. Review treatment goals <strong>and</strong> expectations.<br />
2. Ask the woman to empty her bladder <strong>and</strong> bowels.<br />
3. Ask the woman to assume Semi-Fowler position, a position that is generally<br />
com<strong>for</strong>table <strong>and</strong> offers her a view of the fitting if desired.<br />
4. Gently replace any vault eversion or procidentia prior to sizing.<br />
5. After amply applying water-based lubricant to the vaginal introitus, digitally<br />
assess vaginal size, shape, <strong>and</strong> support, <strong>and</strong> <strong>for</strong> any relative contraindications<br />
to the fitting (pain with palpation, vaginal infection or lesions, full rectum).<br />
6. Select the appropriate stocked pessary or fitting kit model, <strong>and</strong> clean it with<br />
soap, rinsing well with water.<br />
7. Apply additional water-based lubricant to the leading edge of the pessary if<br />
needed.<br />
8. Insert the pessary, applying pressure gently toward the posterior vaginal wall<br />
<strong>and</strong>/or obliquely (at 11:00 <strong>and</strong> 5:00 positions related to the introitus) in the<br />
largest diameter, avoiding pressure on the sensitive urethra.<br />
9. To check initial fit, ask the woman to Valsalva <strong>and</strong> cough (in lithotomy <strong>and</strong><br />
st<strong>and</strong>ing postions) – the correct pessary should be com<strong>for</strong>table <strong>and</strong> may<br />
advance toward the introitus with pressure <strong>and</strong> recede with relaxation, but it<br />
should not pass through the introitus. The examiner should be able to gently<br />
rock the pessary in place, demonstrating that it is not pressing too tightly on the<br />
vaginal walls.<br />
10. Ask the woman to st<strong>and</strong>, move about the examination room, <strong>and</strong> simulate<br />
activities she would normally do (walking, bending to pick up objects on the<br />
floor, changing from st<strong>and</strong>ing to sitting) <strong>and</strong> report any discom<strong>for</strong>t.<br />
11. Ask the woman to sit on the toilet, void, <strong>and</strong> Valsalva gently, simulating<br />
defecation. For actual defecation, it may be helpful <strong>for</strong> her to support the<br />
pessary digitally.<br />
12. If the fitting is successful to this point, review expectations <strong>and</strong> schedule a<br />
return visit. If the pessary is expelled or uncom<strong>for</strong>table, start the fitting process<br />
again.<br />
13. Whether or not the fitting is successful, document any shape <strong>and</strong> size of<br />
pessary used to avoid repeat attempts at subsequent visits.<br />
Insertion <strong>and</strong> Removal of<br />
Specific <strong>Pessaries</strong> <strong>for</strong> Women<br />
With Introital <strong>Support</strong><br />
Ring with <strong>and</strong> without support<br />
membrane. The Ring pessary<br />
<strong>and</strong> Ring with support membrane<br />
(see Figure 2) are common<br />
first-line choices <strong>for</strong> most types<br />
of POP. They typically include a<br />
rigid, hinged nylon ring that fits<br />
into the length of the vagina, providing<br />
support <strong>for</strong> the anterior,<br />
posterior, <strong>and</strong> apical walls. The<br />
optional support membrane may<br />
add additional support if anterior<br />
or posterior compartment prolapse<br />
are present (such as cystocele<br />
or rectocele). The position of<br />
the hinge is marked either by<br />
notches in a Ring or finger-sized<br />
holes in the Ring with support<br />
membrane. To retain this type of<br />
pessary, the introitus <strong>and</strong>/or<br />
pelvic floor must provide enough<br />
support to contain the pessary.<br />
Ring pessaries tend to be easiest<br />
<strong>for</strong> both clinicians <strong>and</strong><br />
patients to use. Many women are<br />
able to remove <strong>and</strong> replace a Ring<br />
pessary without difficulty. Even<br />
when a Ring pessary is in place,<br />
coitus may be com<strong>for</strong>table <strong>for</strong><br />
both partners. Ring pessaries with<br />
or without support are also available<br />
with a urethral support knob<br />
<strong>for</strong> the treatment of stress UI.<br />
To fit a Ring pessary, the vagina<br />
is measured digitally or with a<br />
vaginal measuring instrument to<br />
assess the depth, obtaining a general<br />
idea of the shape <strong>and</strong> size of<br />
the intra-vaginal space (see Figure<br />
8). To insert the pessary, lubrication<br />
of the vagina or a hinged edge<br />
of the pessary <strong>and</strong> not the gloved<br />
exam fingers will facilitate a grip<br />
on the folded pessary. The pessary<br />
is folded in half at the hinge <strong>and</strong><br />
inserted through the introital<br />
opening, while applying gentle<br />
downward posterior or perineal<br />
pressure to avoid the sensitive<br />
urethral area. Once inside the<br />
vagina, the pessary will open<br />
spontaneously. This pessary follows<br />
the length of the vagina,<br />
from loosely behind the symphysis<br />
to the vaginal apex or posterior<br />
<strong>for</strong>nix. A Ring pessary can be<br />
rotated 90 degrees while in-place,<br />
which may help prevent spontaneous<br />
expulsion by placing the<br />
hinge transversely to the introitus.<br />
A well-fit Ring pessary will stay<br />
in place without applying undue<br />
pressure on the sidewalls, apex,<br />
or introitus, <strong>and</strong> will not be<br />
noticeable by the patient. If the<br />
woman describes discom<strong>for</strong>t from<br />
the pessary fitting too near the<br />
introitus during movement, it is<br />
either too large or there is insufficient<br />
introital support to hold the<br />
pessary in place. Removal <strong>and</strong><br />
digital re-sizing may suggest<br />
whether a larger or smaller pessary<br />
may work better. If two or<br />
three tries are not effective, a selfretaining<br />
pessary, such as a<br />
Gellhorn or Cube, may be a better<br />
option.<br />
To remove a Ring pessary,<br />
lubricate the introitus, put an<br />
examining finger through the finger-size<br />
hole or at a hinge notch,<br />
rotate the pessary to bring the<br />
hinge anteriorally to the introi-<br />

tus, <strong>and</strong> gently pull downward,<br />
diagonally, <strong>and</strong> out. The vaginal<br />
walls will help to fold the pessary<br />
as it exits. Atrophic or<br />
scarred tissue may fissure at the<br />
posterior <strong>for</strong>nix with removal.<br />
Increased lubrication, moisturization,<br />
or estrogenation may<br />
ease future use. The most common<br />
sizes of Ring pessary are 2<br />
through 5 (whole numbers).<br />
Donut <strong>and</strong> Inflatable-Donut<br />
pessaries. If a Ring pessary is not<br />
successful, but there is some<br />
introital support, a Donut or<br />
Inflatable-Donut pessary may be an<br />
option (see Figures 3 <strong>and</strong> 4). Donut<br />
pessaries are essentially thicker<br />
Rings <strong>and</strong> may fill a vagina<br />
enlarged by loss of elasticity more<br />
completely; however, these pessaries<br />
are in more complete contact<br />
with the vaginal epithelium, which<br />
may increase the risk of mechanical<br />
tissue injury or discharge production<br />
<strong>and</strong> retention. Some<br />
women may be able to remove <strong>and</strong><br />
replace traditional Donut pessaries<br />
themselves, but com<strong>for</strong>table vaginal<br />
intercourse is unlikely. Infla -<br />
table Donut pessaries, which are a<br />
silicone variation of an older latex<br />
inflatable pessary called the Inflatoball,<br />
have a stem <strong>and</strong> valve <strong>for</strong><br />
inflation <strong>and</strong> deflation like a balloon,<br />
<strong>and</strong> are designed to be inserted<br />
<strong>and</strong> removed at frequent intervals<br />
(within 48 hours). Manu -<br />
facturer instructions should be<br />
reviewed be<strong>for</strong>e attempting to autoclave<br />
Donut pessaries because of<br />
their air-filled core.<br />
During fitting, digital examination<br />
is used to assess both the<br />
depth <strong>and</strong> width of the vagina.<br />
Introital stretching <strong>and</strong> discom<strong>for</strong>t<br />
is more likely with a traditional<br />
Donut, <strong>and</strong> with either type, adequate<br />
lubrication is essential.<br />
With firm digital pressure, a traditional<br />
Donut pessary may be compressed<br />
somewhat to slip through<br />
the introitus more com<strong>for</strong>tably.<br />
Additionally, some Donut pessaries<br />
can be deflated using a needle<br />
<strong>and</strong> syringe to remove air.<br />
After pessary insertion, it can then<br />
be re-inflated by carefully inserting<br />
the needle into the Donut <strong>and</strong><br />
injecting air with the syringe. All<br />
Donut pessaries are typically fit<br />
either like a Ring pessary – along<br />
the length of the vagina – or may<br />
stay in place if fitted snugly into<br />
the circumference of the vaginal<br />
apex with appropriate intrinsic<br />
support.<br />
To remove a traditional Donut<br />
pessary, the introitus is lubricated,<br />
<strong>and</strong> with the examination finger<br />
in the Donut center, the pessary is<br />
pulled gently downward at a diagonal<br />
angle. Some Donut pessaries<br />
can be carefully deflated in situ<br />
using a needle <strong>and</strong> syringe to ease<br />
removal, <strong>and</strong> the Inflatable Donut<br />
pessary should also be deflated<br />
prior to removal.<br />
Other support pessaries re -<br />
quire introital integrity, with indications<br />
based on clinical experience.<br />
They include the Oval<br />
(which may be useful with a narrow<br />
vaginal width); the Hodge <strong>and</strong><br />
Smith Lever pessary (which may<br />
be more com<strong>for</strong>table in women<br />
with a narrow vaginal introitus);<br />
the Gehrung Arch (which may be<br />
effective in women who have an<br />
isolated anterior or posterior wall<br />
prolapse), <strong>and</strong> the Shaatz (which is<br />
a disc, similar to the Ring, but may<br />
offer firmer support). <strong>Fitting</strong> <strong>for</strong><br />
these pessaries is very similar to fitting<br />
of the Ring pessary. Manu -<br />
facturers typically include fitting<br />
instructions with each pessary. If<br />
these types of pessaries cannot be<br />
retained, a self-retaining pessary<br />
may be appropriate.<br />
Insertion <strong>and</strong> Removal<br />
Of Self-Retaining <strong>Pessaries</strong><br />
Gellhorn. The flexible Gellhorn<br />
pessary is an option in women who<br />
cannot retain Ring or similar pessaries<br />
due to introital laxity (see<br />
Figure 5). The shape of the<br />
Gellhorn pessary allows the lateral<br />
vaginal walls to in-fold under<br />
the top dish, while the concave<br />
dish itself may create a suctionlike<br />
action against the proximal<br />
vagina, facilitating pessary retention.<br />
The stem of the Gellhorn follows<br />
the shaft of the vagina, maintaining<br />
correct alignment. The<br />
option of two different stem<br />
lengths (short <strong>and</strong> long) allows<br />
optimal fitting even in women<br />
with a shortened vagina, such as<br />
post-hysterectomy wo men.<br />
Although the ability of the<br />
Gellhorn to be somewhat selfretaining<br />
can be a considerable<br />
advantage, it also makes this pessary<br />
more difficult <strong>for</strong> clinicians<br />
<strong>and</strong> patients to remove. In addition,<br />
the Gellhorn pessary may be<br />
more likely to cause mechanical<br />
trauma to the vaginal tissue. As<br />
with other pessaries, Gellhorn fitting<br />
involves measurement of the<br />
vagina, in this case, assessing both<br />
the diameter of the introitus <strong>and</strong><br />
the apex to approximate the correct<br />
size of the dish <strong>and</strong> of the<br />
vaginal length to determine<br />
whether a long or short neck is<br />
appropriate (see Figure 8).<br />
To insert the flexible Gellhorn,<br />
the stem can be bent down to the<br />
dish <strong>and</strong> the dish folded, with the<br />
edge of the dish inserted first. The<br />
pessary is then corkscrewed gently<br />
down toward the perineum to<br />
avoid the urethra, then upward to<br />
bring the dish perpendicular to<br />
the vaginal vault. The pessary can<br />
then be pushed gently upward<br />
using the index finger on the knob<br />
at the end of the neck, placing the<br />
dish into the vaginal apex. The<br />
woman can then bear down as an<br />
initial assessment of the likelihood<br />
of retention. If two to three<br />
adjustments in the size of the pessary<br />
do not work, a Cube pessary<br />
may be an option.<br />
Removal of a flexible Gellhorn<br />
is generally achieved by lubricating<br />
the introitus, pulling the knob<br />
at the end of the pessary neck gently<br />
downward (toward the introitus)<br />
<strong>and</strong> laterally (toward a thigh),<br />
<strong>and</strong> using the index finger to hook<br />
<strong>and</strong> bend down the edge of the<br />
dish. When the knob cannot be<br />
easily grasped, a carefully placed<br />
tenaculum or ring <strong>for</strong>ceps may be<br />
helpful to assist removal. Gellhorn<br />
pessaries are sized in quarter-inch<br />
intervals by the dish diameter,<br />
with common sizes generally ranging<br />
from 1.75 to 3 inches.<br />
Cube. The Cube pessary can<br />
also be considered self-retaining<br />
122 UROLOGIC NURSING / May-June 2012 / Volume 32 Number 3
SERIES<br />
(see Figure 6). Compared to a<br />
Gellhorn pessary, a smaller size<br />
can be used; however, Cube use<br />
may also result in mechanical tissue<br />
injury. Cube pessaries are<br />
held in place because the concavities<br />
in the six sides allow vaginal<br />
tissue to con<strong>for</strong>m to the pessary<br />
shape. Because large amounts of<br />
epithelium are in contact with the<br />
pessary, drainage holes are important<br />
to allow desquamated cells<br />
<strong>and</strong> vaginal discharge to drain.<br />
The Cube is designed <strong>for</strong> self-care,<br />
but like the Gellhorn, some<br />
women <strong>and</strong> providers find it difficult<br />
to remove due to the suction.<br />
Softness <strong>and</strong> compressibility of<br />
the silicone used vary by manufacturer.<br />
Softer Cubes can be easier<br />
to insert, but firmer devices<br />
may be more likely to be retained,<br />
<strong>and</strong> choice is typically based on<br />
provider experience. The Cube<br />
pessary can be placed at different<br />
depths in the vagina, which may<br />
offer an advantage when a woman<br />
has an isolated or site-specific<br />
prolapse.<br />
Size is estimated by digitally<br />
measuring the diameter of the<br />
vaginal shaft <strong>and</strong> vault. To insert,<br />
lubricate the pessary <strong>and</strong> introitus,<br />
compress the pessary, part the<br />
introitus gently, <strong>and</strong> insert the pessary<br />
to the depth that best corrects<br />
the bulge <strong>and</strong> is most com<strong>for</strong>table<br />
<strong>for</strong> the patient. Com monly used<br />
sizes range from 1 to 4.<br />
To remove, lubricate the in -<br />
troitus, apply gentle traction on<br />
the pessary cord to stabilize <strong>and</strong><br />
bring the device toward the introitus,<br />
<strong>and</strong> then insert the tip of the<br />
index finger up above the Cube to<br />
release it <strong>and</strong> pull it gently out of<br />
the vagina. Pulling too hard on the<br />
cord alone will break the cord. If<br />
removal is difficult, a tenaculum,<br />
ring <strong>for</strong>ceps, pessary remover or<br />
crochet hook, or dental tape tied<br />
through several holes can be used<br />
to facilitate bringing the Cube to<br />
the introitus.<br />
Incontinence Pessary Options<br />
Incontinence pessaries help<br />
stabilize the urethra <strong>and</strong> the urethral<br />
vesicle junction to prevent<br />
leakage during times of increased<br />
abdominal pressure. Options<br />
include the Incontinence Ring or<br />
Dish, which are similar to regular<br />
Ring pessaries but offer less vaginal<br />
support; <strong>and</strong> st<strong>and</strong>ard Ring,<br />
Arch (Gehrung), or Lever (Smith-<br />
Hodge) pessaries with an optional<br />
incontinence support knob. Most<br />
of these pessaries are fitted similarly<br />
to a st<strong>and</strong>ard Ring pessary.<br />
While some women use incontinence<br />
pessaries only during exercise,<br />
others use them continuously.<br />
Generally, the incontinence<br />
knob pessaries are fitted more<br />
snugly behind the symphysis,<br />
beneath the urethra. A pessary<br />
that is too loose will not decrease<br />
stress UI <strong>and</strong> may rotate in the<br />
vagina. Too much pressure may<br />
cause discom<strong>for</strong>t, epithelial in -<br />
jury, <strong>and</strong> urinary retention. If the<br />
woman plans to use the pessary<br />
only intermittently or during<br />
exercise, it may be fitted more<br />
snugly to retain urine. Although<br />
pessaries are typically fitted with<br />
an empty bladder, fitting an<br />
incontinence pessary in a woman<br />
with a full bladder may facilitate<br />
testing of both stress UI treatment<br />
during exercise <strong>and</strong> voiding adequacy.<br />
Suggestions <strong>for</strong> Future Research<br />
Although the evidence base<br />
<strong>for</strong> pessary use has been building<br />
in recent years, much of practice<br />
continues to be based predominantly<br />
on expert-opinion. Prac -<br />
ticing providers may fill some of<br />
these gaps through their own<br />
observations <strong>and</strong> inventiveness,<br />
as well as in <strong>for</strong>mal clinical trials<br />
in their own practice. Nurses<br />
involved in pessary care may be<br />
interested in studying ways to<br />
improve patient satisfaction <strong>and</strong><br />
experience. Questions may in -<br />
clude looking at changes in sexual<br />
function; testing appropriate<br />
pre-trial, goal-setting models;<br />
comparing methods of providing<br />
in<strong>for</strong>mation about pessary op tions<br />
<strong>for</strong> individuals <strong>and</strong> lay groups;<br />
<strong>and</strong> evaluating symptom relief<br />
when pessaries are used in conjunction<br />
with other modalities,<br />
such as anticholinergic medications<br />
or urethral bulking agents.<br />
Expert opinion regarding indications<br />
<strong>for</strong> specific pessary types<br />
should be tested in additional<br />
crossover or head-to-head clinical<br />
pessary trials. Cost analyses related<br />
to different aspects of pessary<br />
use are needed. For example,<br />
comparison of costs of pessary use<br />
over time versus surgery, <strong>and</strong><br />
analysis of potential savings from<br />
morbidity prevention may be useful<br />
both to in<strong>for</strong>m individuals<br />
making treatment choices <strong>and</strong><br />
public policy related to reimbursement.<br />
Conclusion<br />
<strong>Support</strong> pessaries are an<br />
important option <strong>for</strong> treatment of<br />
many pelvic floor symptoms.<br />
Currently, providers new to the<br />
field continue to learn pessary<br />
indications, selection, <strong>and</strong> fitting<br />
strategies from a relatively small<br />
evidence base, <strong>and</strong> occasionally,<br />
from conflicting expert opinion.<br />
This article has summarized basic<br />
concepts related to initiating pessary<br />
use. Other articles in this<br />
series will discuss pessary follow<br />
up <strong>and</strong> business strategies.<br />
