External ureteroneocystostomy in renal transplantation.
The urologic complications of 184 consecutive renal transplants (68 living-related and 116 cadaveric) performed at Walter Reed Army Medical Center are reviewed. An anterior extravesical technique modified from Witzel, Sampson, and Lich was used to reimplant the ureter. Urologic complications occurred in 11 patients (6%): urine leak (4), obstruction (3), stricture (3), and total ureteral necrosis (1). These complications occurred in the first 115 patients; no complications have been documented in the last 69 patients. The several advantages of extravesical ureteroneocystostomy include: less operative time, avoidance of a separate cystotomy, virtually no hematuria, ability to use short ureters, no need for splints or stents, shortened Foley catheter drainage, and no interference with native ureteral function. Complications are few and become uncommon with practice.
