title: Secondary urinoma mimicking recurrent tumor as a cause of bilateral ureteral obstruction.
abstract: A case is reported of a previously resected adenocarcinoma of the rectum presenting with recurrent tumor in the pelvis and an abdominal mass that was found to be a large urinoma. Dialysis was discontinued after drainage of the extravasated urine, and the patient's condition became stable. A review of the literature is also discussed.
