title: Medial deviation of the pelvic ureters after abdominoperineal resection of the rectum.
abstract: Pre- and postoperative urograms of 47 patients undergoing abdominoperineal resection were reviewed for ureteral deviation and obstruction. Postoperative medial deviation occurred in 11 patients (23.4%). Both ureters were involved in six of these patients. Ureteral deviation was identified as early as 3 days after surgery. Obstruction of the ureters occurred in four patients and was due to tumor in three of these.
