Abstract:
We present a case of urethral mucosa prolapse in a postmenopausal woman. Transperineal gray-scale sonograms revealed a clover-shaped, hypoechoic mass protruding from the urethral meatus. Doppler studies revealed blood flow within the protruding mass. Detection of feeding arteries and draining veins contributed to exclude the possibility of necrosis and gangrene, thus allowing conservative medical treatment to be tried. The mucosal prolapse regressed after 1 week's treatment with topical estrogen and antibiotics and sitz baths. Follow-up sonograms showed a normal urethral configuration and diminished vascular flow when compared with the initial study.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
