Intradiverticular tumors of the bladder: surgical implications--an eleven-year review.

Abstract

An 11-year review of all vesical diverticula and bladder tumors was undertaken. Fourteen patients were found to have primary neoplasms arising in the diverticula. The most common type was transitional cell. Hematuria was the most common presentation. Diagnosis is relatively difficult and treatment is not well defined. Lack or thinness of muscular layer of the diverticulum also potentiates early peridiverticular invasion and results in poor prognosis. Early diagnosis and adequate treatment are indicated.
