Evaluation of anterior extravesical ureteroneocystostomy in kidney transplantation

We evaluated the anterior extravesical ureteroneocystostomy technique in 184 consecutive renal transplants done in 2 consecutive calendar years. Complications included 5 cases of ureteral and 1 of pelvic necrosis, and 2 of ureteral obstruction, with a ureteral complication rate of <4 per cent. All cases of pelvic or ureteral necrosis except 1 were seen in cadaver donor kidneys that were imported from other centers. No bladder complications were seen. Pelvioureteral obstruction, presumably of congenital origin in the cadaver donor, was discovered in the kidney after transplantation in 2 cases and was corrected successfully by pyeloureterostomy to the native ureter. The extraordinary simplicity of this technique, coupled with improvement in the complication rate, makes it our procedure of choice.
