输尿管镜下气压弹道碎石术治疗输尿管结石850例效果观察

Analysis on ureteroscopic swiss lithoclast in treatment for ureteral calculi （attached with report of 850 cases）

目的研究输尿管镜下气压弹道碎石术（URSL）对输尿管结石的治疗效果。方法对2006年至2011年来我院就诊的输尿管结石患者850例采用输尿管镜下气压弹道碎石术进行治疗，对患者手术时间，治愈率，并发症，排石时间等指标进行统计和分析。结果850例患者手术成功率98．1％，结石总清除率91．1％，并发症发生率3．29％，手术时间（38±7）min，住院时间（4．5±1．4）d，排石时间（21±5）d，其中5例转为开放式手术，11例转为体外冲击波碎石。结论输尿管镜下气压弹道碎石术能有效清除输尿管结石，手术操作简 便安全，治愈率高，并发症少，是一种较为理想的治疗手段。

ObJective To study the clinical effectiveness of ureteroscopic swiss lithoclast（ URSL ） in treatment for ureteral calculi. Methods The 850 patients we accepted from 2006 to 2011 were treated with URSL. We observed the clearance, operation time, success rate and complication of the patients. Results The patients had a clearance of 91.1%, complication rate of 3.29%, operation time of （38 ± 7） minutes, hospital time of （4.5 ± 1.4） days and calculi removing time of （21 ± 5） days. The success rate of the URSL operation was 98.1% while 16 patients couldn＇ t be cured by URSL. 5 patients of them were transferred to opened technique and 11 patients were transferred to extracorporeal shock wave lithotripsy （ESWL）.Conclusion The URSL can effectively eliminate the ureteral calculi, which is easy and safe for operation with higher cure rate and less complication, and it＇s an ideal treating method.
