Giant Posterior Urethral Calculus Associated with Fournier's Gangrene: Case Report

Urethral calculi are rare and most of them originate in the upper urinary tract or in the bladder. A review of the literature reveals that less than 2% of urinary tract stones are primarily located in the urethra. Urethral calculi are usually associated with urethral stricture or urethral diverticulum and may be lodged in the urethra during their passage. Calculi in the urethral diveticulum may cause recurrent urinary tract infections and a possible Fournier's gangrene. Fournier's gangrene is a form of necrotizing fasciitis affecting the male genitalia. Infection most commonly arises from the skin, urethra or rectal region. Herein, to our knowledge, the first case of an enormously large stone (4.8 x 8.9 x 9.2 cm) in the proximal urethra presenting with Fournier's gangrene is reported.
