Salvage of renal transplant allograft with complete duplication of collectory system by end-to-end and end-to-side pyelo-ureterostomy.

Secondary, ureteroneocystostomy is the procedure most commonly used for repair of ureteral stenosis or necrosis in renal transplant patient. However, when the transplant ureter, the viable part thereof, is too short, uretero-pyelostomy or ureteroureterostomy is the standard procedure. Another option is pyelopyelostomy which is used infrequently. We present a case of a patient with renal allograft with complete duplication of the collectory system, who required reintervention for urinary leak, due to extensive necrosis of both ureters of the allograft. End-to-end and end-to-side pyelo-ureterostomies were performed as rescue procedure for this particular case.
