[Clinical analysis of fifteen transplant ureteral stricture cases].

This research aims to explore the clinical characteristics and treatment of transplant ureteral strictures. We retrospectively analyzed the clinical data from fifteen patients diagnosed with transplant ureteral stricture. Of the fifteen patients, five underwent regular ureteral stent or nephrostomy tube exchanges, while ten underwent open surgery. There were no significant differences in basic clinical characteristics between the two groups. The median follow-up time for regular ureteral stent or nephrostomy tube exchanges and open surgery group was 36.8 (11.8-56.0) months and 25.0 (4.5-31.2) months, respectively. Among patients who underwent regular exchanges, one required regular dialysis. Nine patients in the open surgery group had successful removal of the ureteral stent. Our findings suggest that regular ureteral stent or nephrostomy tube exchanges, as well as open surgery, are effective treatment options for transplant ureteral strictures.本文探讨了移植肾输尿管狭窄的临床特点及处理方式。回顾性分析2015年7月至2021年7月首都医科大学附属北京友谊医院收治的15例移植肾输尿管狭窄患者的临床资料。其中5例患者接受定期更换输尿管支架/肾造瘘管治疗，10例患者行开放手术治疗。两组患者在基本临床资料上差异均无统计学意义（均P>0.05）。更换输尿管支架/肾造瘘管和开放手术患者中位随访时间分别为36.8（11.8~56.0）和25.0（4.5~31.2）个月。定期更换输尿管支架/肾造瘘管组中，1例（1/5）患者出现移植肾失功。开放手术组中，9例（9/10）患者成功拔除输尿管支架。结果说明定期更换移植肾输尿管支架/肾造瘘、开放手术均是治疗移植肾输尿管狭窄的有效方式。.
