两种不同方法对输尿管结石碎石成功率及并发症的影响

目的探讨输尿管镜下钬激光和气压弹道碎石对输尿管结石碎石成功率及并发症的影响。方法选择2011年5；1～2012年5月大庆油田总医院确诊的输尿管结石患者160例，按照随机数字表法分为治钬激光组和气压弹道组，每组各80例。钬激光组给予输尿管镜下钬激光处理输尿管结石，气压弹道组给予气压弹道治疗结石。对比分析两组治疗后碎石成功率及手术相关指标、并发症。结果钬激光组单次腔内碎石成功率为95．0％．气压弹道碎石组单次腔内成功率为72．5％，两组比较，差异有统计学意义（P〈0．05）。两组手术时间比较，差异无统计学意义（P〉0．05）；两组并发症发生率比较，差异有统计学意义（P〈0．05）。经过治疗，钬激光组1～3个月的结石排净率（92．50％）均优于气压弹道组（71．25％），差异有统计学意义（P〈0．05）。结论对于输尿管结石患者，钬激光较气压弹道碎石具有单次手术成功率高、结石排净率高、并发症少等优点，值得临床推广应用。

Clinical effect of two different methods of ureteral calculi gravel success rate and complications

Objective To discuss the clinical effect on holmium laser lithotripsy and pneumatic lithotripsy with ureteroseope in the treatment of ureteral calculi. Methods 180 patients with ureteral calculi in Daqing Oil Field Gen- eral Hospital from May 2011 to May 2012 were selected and divided into holmium laser group and pneumatic lithotripsy group according to random number table, each group had 80 cases. Holmium laser group was given treat- ment of holmium laser while pneumatic lithotripsy group was given treatment of pneumatic lithotripsy. The gravel suc- cess rate and the related surgery indicators, complications after treatment in the two groups were compared and ana- lyzed. Results Single lumen gravel success rate of holmium laser group was 95.0% while that of pneumatic lithotripsy group was 72.5%, there was a significant difference between two groups （P 〈 0.05）. There was no significant difference between two groups on the operation time （P 〉 0.05）. There was a significant difference between two groups on the complication probability （P 〈 0.05）. After treatment, calculus exhaust net rate of holmium laser group （92.50%） after operation of 1-3 months were higher than those of pneumatic lithotripsy group （71.25%） （P 〈 0.05）. Conclusion Holmi- um laser has some advantages such as high single lumen gravel success rate, high calculus exhaust net rate and less complication, so it is worthy of promotion in clinic.
