镍钛合金泌尿系统取石网在输尿管镜碎石术中的临床应用

Clinical application of Stone Cone for ureteral stone in ureteroscopic lithotripsy

目的探讨镍钛合金泌尿系统取石网在输尿管镜碎石术中的手术治疗效果和临床应用价值。方法回顾性分析2014年6月至2015年6月在输尿管镜下应用镍钛合金泌尿系统取石网配合双频双脉冲激光、钬激光或气压弹道超声碎石术治疗30例输尿管结石患者的临床资料。结果30例手术患者平均手术时间（20±11）min。29例患者成功粉碎结石，结石清除率达到96．7％。其中1例结石粉碎后结石碎片漂移至肾盂。所有患者均未发生输尿管撕裂或穿孔等并发症。结论在输尿管镜下碎石术中，镍钛合金泌尿系统取石网能够明显降低粉碎后结石的漂移发生率，提高结石完整清除率。

Objective To explore the therapeutic efficacy of Stone Cone under ureteroscopic lithotripsy and its clinical value in the treatment of ureteral stone. Methods A retrospective analysis of the clinical data of 30 cases of ureteral stone was made in the patients treated with ureteroscopic lithotripsy combined with Stone Cone, and holmium laser or EMS from June 2014 to June 2015 in our hospital. Results The mean surgical time for all the patients that underwent surgery was （20 ± 11 ） min. Ureteral stone was successfully removed in 29 cases, with the stone removal rate of 96.7%. There was 1 case of stone migration to renal pelvis following ureteroscopic lithotripsy. No cases of ureteral laceration or perforation or other complications were found in all the patients following treatment. Conclusions In ureteroscopie lithotripsy, Stone Cone could obviously decrease the rate of stone migration of ureteral stone and increase stone-free rate.
