ENDOURETEROTOMY BY INTRALUMINAL INVAGINATION FOR NONMALIGNANT URETEROINTESTINAL ANASTOMOTIC STRICTURES: DESCRIPTION OF A NEW SURGICAL TECHNIQUE AND LONG-TERM FOLLOWUP

This new endoureterotomy technique for ureterointestinal strictures following urinary diversion can be applied to any type of urinary diversion. It allows direct visualization of the stricture and stricture tissue biopsy. Intraluminal invagination makes it possible to increase the distance between the stricture, and the retroperitoneal vessels and bowels. The technique provides the control required to ensure full-thickness and full-length stricture incision. The success rate is high and it persists after long-term followup.
