We carried out a trial to evaluate the complication rate of intravesical (LP) versus extravesical (Lich) ureteroneocystostomy in recipients of renal transplantation. Ureteric stenosis was the predominant complication in the LP technique, which was more difficult to correct. Complications by the Lich technique were urinary leaks, which were managed successfully by prolonged bladder drainage. We conclude that the Lich technique is simpler to perform and avoids the complication of ureteric stenosis, and should therefore be the procedure of choice for ureteric implantation in recipients of renal transplants.
