摘要
目的：探讨NGage取石网篮联合输尿管镜下气压弹道碎石在治疗上段输尿管结石中的临床应用价值。方法：上段输尿管结石129例，随机分为2组：对照组73例，行单纯输尿管镜下气压弹道碎石；网篮组56例，NGage取石网篮联合输尿管镜下气压弹道碎石。结果：对照组成功碎石并安置D-J管60例，一次碎石成功率82．19％，术后残留结石12例：网篮组一次碎石成功并安置D-J管53例，一次碎石成功率94．64％，明显高于对照组（r=4．522，P=0．033）。术后4～8周复查尿路平片（plainfilmofkidneyureterandbladder，KUB）无残留结石，结石残留率明显低于对照组（χ^2=10．150，P=0．001）。2组手术时间（t=1．847，P=0．067）、术后并发症发生率（r=0．000，P=1．000）、住院时间（t=0．331，P=0．741）差异无统计学意义。结论：NGage取石网篮配合输尿管镜下气压弹道碎石治疗上段输尿管结石可有效防止术中结石移位，提高一次碎石成功率，降低术后结石残留率。
Objective：To investigate the clinical application value of ureteroscope pneumatic lithotripsy（URSL） with NGage extraction basket in the treatment of upper ureteral calculi. Methods ：Totally 129 patients with upper ureteral calculi were randomly divided into two groups,73 patients in control group were treated by URSL,56 patients in Ngage group were treated by URSL combined with NGage. Results：Sixty patients were treated and placed double J （D-J） stents successfully in control group,with the success rate of primary lithotripsy being 82.19%;12 patients had residual fragments after operation. Fifteen-three patients were treated and placed D-J stents successfully in NGage group with the success rate of primary lithotripsy in NGage group being 94.64% ,higher than that of control group（χ^2=4.522,P=0.033）;residual calculi was not found at 4-8 weeks after operation by plain film of kidney ureter and bladder. Rate of residual calculi in N Gage group was significantly lower than that in control group （χ^2=10.150,P=0.001）. There was no significant difference between two groups in the operation time（t=1.847,P=0.067）, complication rate（χ^2=0.000,P=1.000） and hos- pitalization time（t=0.331 ,P=0.741）. Conclusions：URSL with NGage extraction basket can efficaciously prevent calculi from moving upward in the treatment of upper ureteral calculi,which can achieve higher success rate and lower residual calculi rate.
