Urethral recurrence of transitional cell carcinoma of the bladder. Predictive value of preoperative latero-montanal biopsies and urethral frozen sections during prostatocystectomy.

The urethral frozen section was the only guideline used for simultaneously performing the urethrectomy. All male patients with negative frozen cut sections should be considered candidates for bladder substitution. A prophylactic urethrectomy is only indicated in patients with carcinoma (minimum carcinoma in situ) in the frozen urethral margin section during cystectomy.
