To conduct a prospective, multi-center study to observe the long-term efficacy and safety of self expanding ureteral stent for treating participants with refractory ureteral stricture.
The aim of the study is to conduct a prospective, multi-center study to observe the long-term efficacy and safety of self expanding ureteral stent for treating participants with refractory ureteral stricture. About 200 participants with refractory ureteral stricture will be enrolled in four hospitals. After the allium ureteral stents are placed, renal function, renal echo, images and associated complications will be recorded.
