输尿管镜钬激光碎石与气压弹道碎石的比较

Comparative study of ureteroscope pneumatic lithotripsy and ureteroscope holmium laser lithotripsy for ureteral calculi

目的:比较输尿管镜下钬激光碎石术与气压弹道碎石术治疗输尿管结石的疗效与安全性。方法:回顾性分析输尿管镜下治疗76例输尿管结石患者的临床资料,其中采用钬激光碎石治疗36例(钬激光组),气压弹道碎石治疗40例(气压弹道组)。结果:钬激光组平均术中碎石时间为8min,明显短于气压弹道组15min(P<0.01)。钬激光组碎石成功率为97.2%,明显高于气压弹道碎石组的87.5%(P<0.01)。两组手术均较安全,无明显相关并发症出现。结论:钬激光碎石术的有效性优于气压弹道碎石术,是一种治疗输尿管结石安全、高效的方法。

Objective： To compare the efficacy and safety of ureteroscope pneumatic lithotripsy and uretero scope laser lithotripsy for ureteral calculi. Methods： Retrospectively analyse 76 consecutive patients underwent ureteroscope lithotripsy either with the Swiss Lithoclast pneumatic lithotripter （40 cases） or with Holmium laser lithotripter （36 cases） for the treatment of ureteral calculi. Results： The successful rate of calculi fragmentation of ULLwas higher than that of UPL （97.2% vs 87.5%, P〈0.01）. The average litbotripsy time for ULL was shorter than that of UPL （8 rain vs 15 min, P〈0.01）. No major complication has been observed in both ULL and UPL. Conclusions：ULL. has its advantage over UPL in high efficiency of calculi fragmentation and is an effective and safe treatment modality for ureteral calculi.
