[Ureteral stenoses after renal transplantation]

Out of 953 kidney transplantations performed in Lyon up to the end of 1984, we observed 28 (2.9%) post-operative ureteral stenoses. Most of them were diagnosed during the first year post-transplantation. Surgical reparation of the stenosis involved either ureterovesical reimplantation or pyeloureteral anastomosis with the patients' own ureter. Return to normal renal function was observed in 64.2% of our patients while in 10.7% renal function was stabilized. Actuarial postoperative graft survival was 66% at one year and 58% at two years of follow-up.
