[Urethral diverticula surrounding the urethra in women: report of 2 cases]
1Department of Urology, Izumi City Hospital.
Abstract:
We report two cases of female urethral diverticula. A 49-year-old woman (case 1) complained of perineal pain when she voided urine. A 36-year-old woman (case 2) complained of perineal pain. In both cases, intravenous pyerography and urethrography revealed diverticula around their urethra, and we diagnosed them with urethral diverticula which surrounded their urethra by magnetic resonance imaging. We treated them by transvaginal diverticulectomy. Case 2 was successfully treated, but the diverticulum recurred after one year in case 1. There are over 200 reported cases of female diverticula in the Japanese literature, but a urethral diverticulum surrounding the urethra is rare.
