目的总结输尿管鞘在输尿管中下段>1.5cm结石中的应用经验。方法回顾分析2015年10月至2016年10月我院采用输尿管鞘建立工作通道后,行钬激光碎石治疗输尿管中下段>1.5cm结石的28例患者临床资料。结果所有患者术后均未见临床有意义的残石,且无输尿管穿孔、狭窄及大出血等并发症发生。结论通过输尿管鞘建立工作通道,处理输尿管中下段>1.5cm结石,可以最大程度地避免由于输尿管镜频繁进出输尿管而引起的损伤,并且缩短手术时间,提高结石清除率,降低手术风险。
Objective To summarize the experience of application of ureteral sheath in> 1.5cm stones in the lower ureter. Methods The clinical data of 28 patients who underwent ureteral sheath in our hospital from October 2015 to October 2016 were treated with holmium laser lithotripsy for> 1.5cm stones in the lower ureter. Results All patients had no clinically significant residual stone after surgery, and no complications such as ureter perforation, stenosis and hemorrhage occurred. Conclusion Through the ureteral sheath to establish the working channel, the treatment of ureteral stones in the lower middle> 1.5cm, ureteral mirror can be avoided as much as possible to enter and exit the ureteral injury, and shorten the operation time, improve the stone clearance rate and reduce the surgical risk.
