气压弹道碎石术与钬激光碎石术治疗膀胱结石的比较

Comparative study of pneumatic lithotripsy and holmium:YAG laser lithotripsy for vesical calculi

目的比较经膀胱镜气压弹道碎石术与钬激光碎石术治疗膀胱结石的疗效和实用性。方法采用膀胱镜气压弹道碎石术治疗膀胱结石患者162例,钬激光碎石术76例。比较两组手术时间、手术并发症的发生率。结石排净率的差异。结果钬激光碎石术手术时间平均为31.5分,少于气压弹道碎石术47.1分,P<0.01;钬激光碎石术结石排净率为97.4%,与气压弹道碎石术的96.9%无显著差异。钬激光碎石组无明显并发症发生,气压弹道碎石组有5例中转开放手术。结论钬激光碎石术的疗效和实用性优于气压弹道碎石术。

[Objective] To compare the efficacy and practicability of endoscopic pneumatic lithotripsy （PL） and endoscopic holmium：YAG laser lithotripsy （LL） for vesical calculi. [Methods] 162 patients underwent endoscopy with pneumatic lithotripsy ,76 patients underwent endoscopic with holmium：YAG laser lithotripsy. The operation time, stone-free rate and incidence rate of complications were compared between the 2 groups. [Results] The mean operation time of vesicoscope with holmium：YAG laser lithotripsy for vesical calculi was shorter than that with pneumatic lithotripsy. The stone-free rate with pneumatic lithotripsy and holmium：YAG laser lithotripsy were 96.9% and 97.4%, respectively （P 〉0.05）. No major complication has been observed in LL whereas 5 perforations were encountered in PL. [Conclusions] Endoscopic holmium：YAG laser lithotripsy for vesical calculi is more effective and safe than endoscopic pneumatic lithotripsy.
