Benign ureteral stricture refers to a urinary tract obstruction caused by a partial or full ureteral lumen that is less normal than normal. It can lead to urinary dilatation, water accumulation, and renal colic in the upper segment of the stenosis. If treat not in time, it will affect renal function and even causes irreversible kidney failure.In recent years, with the development of endoscopic techniques, it provides a cost-effective and less invasive treatment for the treatment of ureteral stricture. In recent years, with the development of endoscopic techniques, it has provided a cost-effective and less invasive treatment for the treatment of ureteral stricture, and has achieved satisfactory results. Therefore, more and more urologists choose to treat ureteral stricture under endoscopy. The techniques of urinary endoscopic treatment of benign ureteral stricture include ureteral balloon dilatation, ureteral holmium laser incision, and ureteral stent implantation. Among them, the ureteral balloon dilatation technique is characterized by the use of a balloon to uniformly force the ureteral wall, tearing the narrow scar tissue, expanding the inner diameter of the ureter, recanalizing the urinary tract, and alleviating hydronephrosis. It have been reported with less complications and simple procedure. However, there's still no consensus on its treatment indication，procedure standards and curative effect. This study is designed to treat benign ureteral stricture with balloon dilatation through prospective multicenter studies. It aims to indications, procedure standards, and therapeutic effects of balloon dilation, and provide further guidance for endoscopic treatment of benign ureteral stricture.
