URETEROENTERIC ANASTOMOSIS IN CONTINENT URINARY DIVERSION: LONG-TERM RESULTS AND COMPLICATIONS OF DIRECT VERSUS NONREFLUXING TECHNIQUES

Abstract

Nonrefluxing methods of ureterointestinal reimplantation resulted in a statistically significant higher rate of anastomotic stricture than the end-to-side direct anastomosis. This finding appears to outweigh any theoretical benefits of preventing pyelonephritis, stones or azotemia. For patients undergoing large volume, low pressure continent diversion the refluxing ureterointestinal anastomosis may be the technique of choice since it preserves renal function as well as the nonrefluxing method, is technically easier to perform and poses less risk of stricture. Delayed stricture formation years after surgery underscores the necessity for long-term radiological followup in patients following continent diversion.
