结石拦截网在输尿管镜气压弹道碎石术中的应用

The application of calculus interception net in the ureteroscopic pneumatic lithotripsy

目的探讨结石拦截网在输尿管镜气压弹道碎石治疗输尿管中下段结石术中的应用价值。方法输尿管镜气压弹道碎石术中联合应用结石拦截网治疗输尿管中下段结石48例,其中输尿管中段结石18例,下段结石30例,男32例,女16例,结石长径0.7～2.0cm,左侧输尿管结石22例,右侧26例,其中双侧输尿管结石6例,合并膀胱结石4例。结果46例拦截成功并完成碎石,2例结石上移至肾内,拦截成功率为95.8%(46/48)。术中无输尿管穿孔和黏膜撕脱等并发症发生。结论结石拦截网可有效防止输尿管镜气压弹道碎石过程中结石移位,提高碎石成功率,其操作简单,值得临床应用推广。

Objectives To study the application value of calculus interception net in the ureteroscopic pneumatic lithotripsy for the treatment of upper and middle ureteral calculus. Medthods 48 （32 males and 16 females） patients with upper and middle ureteral calculus underwent transureteroscopic pneumatic lithotripsy with calculus interception net, among which, 32 were male and 16 were female. The diameter of ureteral calculus were 0.7-2.0 cm. There were 18 upper ureteral calculus and 30 middle ureteral calculus; 22 leftside ureteral calculus and 26 right side ureteral calculus. There were 6 both-sides crinosity calculus accompartied with 4 cases of vesical calculus. Results Among 48 cases, there were 17 cases of successful macadam of upper ureteral calculus （94.4%） and 1 case of upward calculus; 29 cases of middle ureteral calculus（96.6%） and 1 case of ineffective calculus interception. Conclusions Calculus Interception Net could effectively prevent calculus upward during ureteroscopic pneumatic lithotripsy process, with the advantages of conveniency, safety and high-efficiency, which is worth to be promoted in clinical application.
