Vesical diverticula: etiology, diagnosis, tumorigenesis, and treatment. Analysis of 74 cases.

A thirteen-year review of bladder diverticula was undertaken and 74 cases were identified. In 8 patients primary neoplasms arose in the diverticula, and their treatment included diverticulectomy or partial cystectomy with or without postoperative irradiation, irradiation only, and transurethral resection of the tumor combined with fulguration of the diverticular wall and postoperative bladder instillations with doxorubicin or thiotepa solutions. Early diagnosis with additional visualization of the interior of vesical diverticulum is mandatory, since carcinoma arising in it has a poor prognosis.
