title: Adenomatous polyp in defunctionalized colonic segment used as a urinary bladder.
abstract: For transitional cell carcinoma of the urinary bladder, an eighty-two-year-old man underwent cystoprostatectomy. His urine was diverted to a defunctionalized right colonic segment used to replace his bladder. Four months after the surgery, gross hematuria appeared; endoscopy disclosed an adenomatous polyp in the substitute bladder. We review the incidence and origin of neoplasia in colonic segments used for urinary diversion.
