The successful transplantation of a cadaver kidney with ureteral duplication employed ureteroneocystostomy to reestablish urinary tract continuity. Cadaver kidneys with ureteral duplication can be satisfactory renal allografts if care is taken to preserve the branches of the renal artery which provide the arterial blood supply to the allograft ureter, if the double ureters are dissected en bloc within their common adventitial sheath, and if the bladder serosa and muscularis incisions are generous enough to easily accommodate the double ureter. Donor kidney ureteroureterostomy followed by an anastomosis to the recipient ureter provides an alternative if the blood supply to the double ureters has been jeopardized.
