Diverticula and Valves of the Anterior Male Urethra
Valves of the male urethra usually start as diverticula due to a defect in the wall of the corpus spongiosum. With further ballooning of the diverticulum, the distal edge becomes obstructive and acts as a valve. The obstruction and the damage to the urinary tract may be as severe as in posterior urethral valves, but it is less likely.
The diagnosis is made by a voiding cysturethrogram (VCUG), retrograde urethrography and cystoscopy. Initial treatment in severe urinary tract damage is done with a vesicostomy. Definite treatment consists of either transurethral incision of the distal edge or open urethral reconstruction.
