Diverticula may take their origin from any part of the urinary bladder, although by far the majority spring from the lateral walls, not far from the ureters. Their pathogenesis is still unknown. That some are congenital is evidenced by an analogous condition in fetal bladders, as shown by Watson.1 However, it is generally believed that they are acquired secondary to some congenital defect in the bladder wall.
The possibility of encountering bladder tissue in the performance of inguinal hernia has been frequently stressed. In a fairly exhaustive review of the literature, I have failed to find a case report of a bladder diverticulum in the inguinal canal.
