Urothelial carcinoma in a urinary bladder diverticulum: A case report and review of the literature

Abstract

Bladder diverticula are defined as an outpouching of the mucosa into the muscle layer of the bladder wall. There is a well-known link between urinary bladder diverticula and tumors arising within the diverticula. They are rare with an incidence rate of 0.8%-10%. We report an intradiverticular urothelial carcinoma in a 72-year-old man with a known history of multiple episodes of acute urinary retention and urinary tract infections, followed by transurethral resection of the benign prostatic hyperplasia.
