Late Ureteral Stenosis After Kidney Transplantation: A Single-Center Experience

Abstract In a retrospective study, we analyzed 1419 consecutive kidney transplantation procedures performed at a single center to identify potential predictive factors of ureteral stenosis. Only stenosis observed after the first month posttransplantation was considered. The Cox proportional hazard r...

Description
Summary:Abstract In a retrospective study, we analyzed 1419 consecutive kidney transplantation procedures performed at a single center to identify potential predictive factors of ureteral stenosis. Only stenosis observed after the first month posttransplantation was considered. The Cox proportional hazard regression model was used to analyze donor age and serum creatinine concentration before procurement, recipient age, cold ischemia time, delayed graft function, number of renal arteries, and presence of a double-J stent. Follow-up evaluation included number and timing of acute rejection episodes, cytomegalovirus infection, acute pyelonephritis, renal function, and patient death. Ureteral stenosis developed in 45 patients (3.17%), and was correlated with donor age older than 65 years ( P = .001), kidneys with more than 2 arteries ( P = .009), and delayed graft function ( P = .02). The data suggest a potential protective role of donor age, number of renal arteries, and delayed graft function in development of ureteral stenosis after kidney transplantation.
