Ureteral complications are one of the most common complications after kidney transplant. Although these complications have been treated surgically in the past, almost all can be successfully treated with interventional methods today. In this study, we assessed the interventional treatment of ureteral complications after kidney transplants performed in our center and the long-term results of these treatments. We performed a retrospective analysis of 2223 kidney transplant recipients seen between January 1, 2000, and May 1, 2020. Among these, 70 kidney transplant recipients who experienced ureteral leakage or ureteral obstruction in the early or late posttransplant period were included in the study. Complications within the first 2 months posttransplant were classified as early complications, whereas those occurring after 2 months were considered late complications. We treated all patients with interventional methods. In review of patients, 44 patients were diagnosed with ureteral obstruction (22 patients were early obstruction, 22 were late obstruction) and 26 patients with ureteral anastomosis leakage. All patients with early and late ureteral obstruction were successfully treated with percutaneous methods. In the group of patients with ureteral leakage, all patients except 2 patients were treated with interventional methods. For 2 patients with ureteral leakage, surgical treatment was necessary because of persistent leakage despite percutaneous treatment methods. Ureteral complications after kidney transplant can be successfully treated with interventional methods in experienced centers without the need for surgery.
