[Treatment of complex fistula and urinary stenosis in renal transplantation].
OBJECTIVE
Urological complications in renal transplantation occasionally denote the failure of a technique intended to provide the patient on hemodialysis a significant improvement of quality of life. Our experience in the management of these complicated cases which could not be resolved by conventional measures is described.


METHODS
Since the transplantation program began, our department has performed 530 renal transplants. There have been 40 fistulae (7.5%) and 23 stenoses (4.3%) of graft urinary tract. All the foregoing complications had been treated by endourological procedures (nephrostomy or ureteral stent) and/or simple ureteral reinsertion. There were 5 unresolved or recurrent fistulae (0.9%) and 2 stenoses (0.4%) that were repaired using the recipient's ipsilateral urinary tract (6 pyeloureterostomies and 1 pyelopyelostomy).


RESULTS
Good results were achieved in all of the cases with adequate urinary tract function.


CONCLUSIONS
Urological complications following renal transplantation can be successfully treated by surgical correction (pyeloureterostomy or pyelopyelostomy).
