目的:探讨肾结石采用钬激光碎石取石术在微通道以及标准通道经皮肾镜下的治疗效果,并对两者进行比较。方法:将肾结石患者209例随机分为观察组和对照组,两组都采用钬激光碎石取石术进行治疗,对照组借助微通道经皮肾镜,观察组借助标准通道经皮肾镜。结果:平均手术时间,对照组为136min,观察组为82min,观察组短于对照组,比较具有统计学差异(P<0.05)。一期结石清除率,观察组为92.5%,对照组为71.5%,观察组好于对照组(P<0.05)。平均住院时间,观察组为8.1d,对照组为7.8d比较没有统计学差异(P>0.05)。两组手术后血红蛋白下降率,观察组和对照组分别为7.5%、7.2%(P>0.05)。结论:钬激光碎石取石术,标准通道同微通道经皮输尿管镜相比,手术时间更短、结石清除率更高,值得在肾结石治疗中应用。
OBJECTIVE: To investigate the therapeutic effect of renal calculus with holmium laser lithotripsy on microchannels and standard channels percutaneous nephrolithotomy, and to compare the two. Methods: 209 patients with kidney stones were randomly divided into observation group and control group. Both groups were treated by holmium laser lithotripsy. Microcirculation percutaneous nephrolithotomy was used in the control group and percutaneous nephrolithotomy was used in the observation group. Results: The average operative time was 136 minutes in the control group and 82 minutes in the observation group. The observation group was shorter than the control group (P <0.05). A stage of stone clearance, the observation group was 92.5%, 71.5% in the control group, the observation group was better than the control group (P <0.05). The average length of hospital stay was 8.1 days in the observation group and 7.8 days in the control group, with no significant difference (P> 0.05). The hemoglobin decline rate of the two groups after operation was 7.5% and 7.2% in the observation group and the control group respectively (P> 0.05). Conclusion: Holmium laser lithotripsy, the standard channel with micro-channel percutaneous ureteroscopy, shorter operation time, higher stone clearance, it is worth in the treatment of kidney stones.
