(Top) Transverse transabdominal grayscale ultrasound shows the suprapubic region at the uterine body level. The transducer must be
angled caudally to image the urinary bladder, especially when it is not well distended and assumes a retropubic location. (Middle)
Longitudinal transabdominal grayscale ultrasound at the suprapubic region shows a well-distended urinary bladder with a posteriorly
located uterus. Note the anechoic appearance of the urinary bladder due to its fluid-filled state, which acts as an acoustic window,
permitting through transmission of the ultrasound beam and optimal visualization of posterior pelvic structures. (Bottom) Transverse
color Doppler ultrasound of the bladder in the suprapubic region shows ureteral jets.
