Purpose To compare long-term graft and patient survival after percutaneous angioplasty (PTA) or stent placement for transplant renal artery stenosis (TRAS) with a control cohort without TRAS. Materials and Methods This is a retrospective matched cohort study of 41 patients (median age, 49 years; range, 18-72 years), including 27 male patients (median age, 48 years; range, 18-67 years) and 14 female patients (median age, 52 years; range, 24-68 years), with TRAS from December 1995 through 2016. Primary end points were death-censored graft and patient survival, compared by using log-rank test and Cox proportional regression.

Materials and Methods An ethical waiver was obtained for this 23-year retrospective matched cohort study of 52 of 1476 consecutive kidney transplant recipients who developed postoperative ureteric stenosis. Data were collected between January 1990 and December 2012.

Materials And Methods: Radiologic and clinical databases were used to identify all adult patients who underwent renal transplantation from January 1994 through December 2012. Patients who underwent transplant percutaneous nephrostomy catheter insertion for the immediate management of ureteric obstruction or leak were identified, and the 30-day outcomes were recorded.
