Answer

Diverticular cancers comprise 1.5-10% of all bladder cancers and are more likely to penetrate the bladder wall because of the relatively thin nature of the wall and its lack of thick muscular layers. Transurethral resection of the tumor may be an option; however, inadvertent perforation is possible because of the paucity of muscle fibers in the diverticulum, which may lead to dissemination of urothelial cancer cells. Urothelial carcinoma in a bladder diverticulum is a common reason for performing partial cystectomy. Historical series suggested a high rate of recurrence and poor prognosis for diverticular tumors, but more contemporary data suggest that complete tumor resection with partial cystectomy results in 5-year disease-specific survival rates of around 70%.
