The use of contralateral native pelvis and ureter for total transplant ureteric reconstruction

Ureteric strictures after transplantation are infrequent and may result in failure of the allograft. The treatments of choice are ureteroneocystostomy or an endourological procedure [1,2], but when the stricture is too long to reimplant, ipsilateral pyeloureterostomy or pyelopyelostomy, joining the distal portion of the ipsilateral native ureter or pelvis to the pelvis of the renal graft, constitutes the standard ureteric reconstruction [3]. Pyelopyelostomy was described first by Carpus et al. in 1968 and then by Wagner and Dieckmann in 1994 [4]. We report the result of a different kind of pyelopyelostomy, joining the contralateral pelvis to the pelvis of the renal graft [5] in two patients.
