Preoperatively Dilated Ureters are a Specific Risk Factor for the Development of Ureteroenteric Strictures after Open Radical Cystectomy and Ileal Neobladder

Preoperatively obstructed ureters are at significantly higher risk for benign ureteroenteric anastomosis strictures during the postoperative course after ileal neobladder diversion. Most such Le Duc strictures are bilateral and most such Wallace type strictures are unilateral. The risk of ureteroenteric anastomosis stricture after ureteroenterostomy using the nonrefluxing technique is threefold the risk of the refluxing technique. There was no preponderance of left ureteroenteric anastomosis strictures after each technique.
