目的：探讨经输尿管镜碎石术治疗输尿管中、下段结石术后留置输尿管支架的必要性。方法将112例输尿管中、下段结石患者分为两组，A组（未留置支架）56例，B组（留置支架）56例，比较两组患者间手术时间、结石清除率、支架相关疼痛评分（VAS）、尿路症状评分（USSQ）、肉眼血尿发生率、泌尿系感染率及输尿管狭窄发生率。结果两组患者手术时间、结石清除率、泌尿系感染率比较，差异无统计学意义（P＞0．05）；A组患者术后 VAS评分、USSQ、肉眼血尿发生率均明显低于 B组，差异有统计学意义（P＜0．05），两组均未出现输尿管狭窄。结论经输尿管镜碎石术治疗单纯输尿管中、下段结石不必留置输尿管支架。

Objective To investigate the necessity of indwelling ureteral stent after ureteroscopic lithotripsy for treating middle-lower ureteral calculi.Methods 1 1 2 patients with middle-lower ureteral calculi were divided into 2 groups.The group A(non-indwelling stent,n=56)and the group B(indwelling stent,n=56).The operative time,stone clearance rate,stent-related pain scores(VAS),urinary tract symptom scores (USSQ),gross hematuria,urinary tract infection and occurrence rate of postoperative ureteral stenosis were compared between the two groups.Results The operative time,stone clearance rate and urinary infection had no statistical difference between the two groups(P>0.05).The postoperative VAS scores,USSQ scores and occurrence rate of gross hematuria in the group A were significantly lower than those in the group B(P<0.05),no ureterostenosis happened in both groups.Conclusion Indwelling ureteral stenting is unnecessary in ureteroscopic lithotripsy for treating simple middle-lower ure-teral calculi.
