目的　总结腔内泌尿外科技术治疗输尿管狭窄的疗效。　方法　对 182例采用腔内泌尿外科技术治疗的输尿管狭窄病人资料进行回顾性分析。　结果　 33例炎症和息肉引起狭窄的病人 ,采用激光或电凝等治疗 2 7例 ,成功率 82 %。手术损伤导致狭窄 149例 ,采用输尿管镜直视下扩张术 10 8例 ,气囊扩张 17例 ,输尿管导管扩张术 11例 ,输尿管镜直视下冷刀切开术 13例 ,成功率分别为 80 % ,71% ,6 4% ,85 %。　结论　输尿管镜直视下扩张术结合双J管引流 ,对创伤引起的输尿管狭窄具有较满意的疗效。输尿管镜直视下冷刀切开术疗效更好 ,但需要一定经验 ,并发症也较多 Objective To summarize the curative effect of endourology on ureteral stricture. Methods A retrospective analysis was performed on 182 patients with ureteral stricture treated with endourology. Results Twenty-seven patients with inflammation and polyps caused by stenosis were treated with laser or electrocoagulation. The success rate was 82%. Surgical injury led to stenosis in 149 cases, ureteroscopic direct use under the dilation of 108 cases, balloon dilatation in 17 cases, ureteral catheterization in 11 cases, ureteroscopy under cold knife in 13 cases, the success rates were 80% , 71%, 64%, 85%. Conclusions Ureteroscopic dilatation combined with double J-tube drainage has satisfactory therapeutic effect on trauma-induced ureteral stricture. Ureteroscopy cold knife incision under curative effect is better, but requires some experience, complications are more
