Urologic complications following abdominoperineal resection.

In a retrospective study we analyzed the high incidence of 75 urological complications after abdominoperineal resection in 52 patients. A prospective study was done also to anticipate as well as to minimize or eliminate these highly significant complications. Direct injury leading to obstruction and fistula formation was avoided. Obstructive uropathy in 10 of 25 male patients was found as a direct result of preoperative evaluation. Same day prostatectomies in 5 patients made no appreciable difference in the urological management, complication rate or end results. Neurogenic bladder dysfunction of various degrees was found in 50 per cent of all patients but represented a long-term problem in only 10 per cent.
