输尿管镜气压弹道碎石术治疗尿道结石

Clinical Analysis about Treatment of Urethral Calculi with Ballistic Lithotripsy under Ureteroscope

[目的]探讨应用输尿管镜直视下气压弹道碎石术治疗前、后尿道结石的效果。[方法]回顾性分析96例尿道结石的诊治经过,其中应用直接钳夹法治疗18例前尿道结石患者;采用输尿管镜直视下气压弹道碎石术对20例前尿道结石患者及58例后尿道结石患者进行治疗。[结果]前尿道结石经直接钳夹取出率94.4%,应用输尿管镜直视下气压弹道碎石术治疗结石取出率100%;直接钳夹法致尿道狭窄率16.7%,经输尿管镜下气压弹道碎石治疗未出现尿道狭窄。后尿道结石采用输尿管镜直视下气压弹道碎石术治疗一次原位碎石成功54例,成功率为93.1%、碎石时间为30～50min。并发症发生率为3.4%。[结论]输尿管镜下气压弹道碎石术治疗无论在治疗前尿道结石还是后尿道结石中均其有微创,安全,高效,容易操作的特点,值得推广。

[Objective] To evaluate the therapeutic effects of ballistic lithotripsy for the anterior urethral calculi and posterior urethral calculi . [Method]The treatment of 96 cases of urethral calculi was retrospectively analyzed. 20 patients of anterior urethral calculi were treated by ballisticl ithbtripsy under uretemscope and compared with 18 counterparts. Treat 58 patients of posterior urethral calculi by ballistiel ithbtripsy under uretemscope occurred. [Results] The success rate of adopting ballisticl ithbtripsy was 100% and didn＇t have complication in the cases operated anterior urethral calculi in contrast to 94.4% in ring clamping group and 16.7% with urethrostenosis. 54 patients suffered from posterior urethral calculi were treated successfuly in a single procedure by ballistict ithbtripsy under uretemscope. The duration of lithotripsy was 30- 50 minutes. Urethral stricture occurred in 3.4% patients. [Conclusion] Ballisticl ithotripsy under ureteropyeloscopy is an effective and simple treatment for the urethral calculi.
