摘要目的：评价封堵取石导管在输尿管镜上段碎石术中的应用价值。方法回顾性分析使用封堵取石导管行输尿管镜上段碎石治疗62例（ A组）及单纯行输尿管镜上段碎石治疗58例（ B组）的临床资料，就两组结石清除率、手术时间、术中出血量、住院天数及并发症等指标进行比较。结果两组结石清除率有显著性差异（ P ＜0．05）；在手术时间、术中出血量、住院天数及并发症等方面差异无统计学意义（ P ＞0．05）。结论输尿管镜上段碎石术中联合使用封堵取石导管能增加结石清除率，提高手术成功率，增加患者满意度，不增加手术时间、出血量、住院天数及手术并发症，值得临床推广。

abstractsObjectives To evaluate the clinical value of ureteral occlusion device in ureteroscope lithotrip-sy for upper ureteral calculi.Methods The clinical data of 120 cases of patients with upper ureteral calculus were analyzed retrospectively.Among them,62 cases( group A) were treated by ureteroscope lithotripsy combined with ure-teral occlusion device and 58 cases(group B) were treated by ureteroscope lithotripsy.The stone-free rate, operat-ing time, blood loss during operation, the hospital stay, and complications were compared between group A and group B.Results n group A the stone-free rate was better than that in group B( P <0.05);The differences in operating time, blood loss during operation, the hospital stay, and complications were not statistically significant( P>0.05).Conclusions Ureteroscopy lithotripsy combined with ureteral occlusion device deserves clinical appli-cation because it can increase stone-free rate, improve success rate of lithotripsy and increase patients satisfaction . Meanwhile,It does not increase the operating time, blood loss during operation, the hospital stay and complications.
