title: Ureteral stenosis after kidney transplantation: true incidence and long-term followup after surgical correction.
abstract: Between March 1965 and December 31, 1982, 421 kidney transplantations were performed in our department. The over-all incidence of ureteral stenosis was 5.5 per cent. However, when the number of patients at risk at various times after transplantation was considered the probability for ureteral stenosis to develop was 4.6 per cent at 1 year, 7.7 per cent at 2 years and 9.7 per cent at 5 years. Preoperative and postoperative complications were frequent. The wound infection rate was 21.9 per cent and 2 of the 24 patients died of septic shock. Graft survival rate after definitive surgical correction of ureteral stenosis was 71 per cent at 1 and 2 years, and 65 per cent at 3 years. Late results justify the efforts to re-establish correct urinary drainage of the graft.
