Ectopic ureter presenting in midline urethral diverticulum.

A rare case of an ectopic ureter terminating in a urethral diverticulum is presented. While numerous cases of extravesical ectopic ureters draining directly into the urethra or uterovaginal canal have been reported, the termination of a ureter as a diverticular sac is extremely unusual. Moreover, only rarely has a urethral diverticulum been documented to arise congenitally due to any cause. The history and management of this new case are detailed, and the general subjects of ectopic ureter and urethral diverticulum are discussed with particular reference to etiology and continence.
