Diagnostic Ultrasound - Abdomen and Pelvis

Ureterocele
(Left) Transabdominal
longitudinal ultrasound shows
a small ureterocele st with
upstream ureteral dilation .
(Right) Transverse oblique
transabdominal ultrasound
shows an echogenic stone
impacted at the right
ureterovesical junction
with upstream ureteral
dilation . Focal bulge at the
intramural segment of the
ureter is compatible with
pseudoureterocele .
Diagnoses: Urinary Tract
(Left) Voiding
cystourethrogram shows a
round filling defect within
the urinary bladder
compatible with a ureterocele.
(Right) Coronal heavily T2-
weighted MR shows left renal
duplex collecting system with
dilated upper moiety and
decompressed lower moiety
. The upper moiety is seen
continuous with significantly
dilated and tortuous ureter
seen terminating in an
intravesical ureterocele .
(Left) Axial CT urogram
through the pelvis shows left
duplex system with the upper
moiety terminating in a
ureterocele that contained
calculi. The lower moiety
ureter is nondilated and seen
terminating adjacent to the
ureterocele . Note the
prostatic impression at the
bladder base . (Right) 3D
reformatted MIP image of the
CT Urogram (posterior view)
shows the duplicated left
collecting system with calculi
in the ureteropelvic junction
and in the ureterocele of
upper moiety.
