Retroperitoneal urothelial carcinoma arising after bladder diverticulectomy: a case report.

ABSTRACT:

Background

Urothelial carcinoma arises from the inner urothelial membrane of the renal pelvis, ureter, and bladder and often causes macrohematuria. Here, we report a rare case in which the patient developed non-symptomatic urothelial carcinoma anatomically outside the bladder wall 17 years after bladder diverticulectomy.
