目的 探讨微创经皮肾镜钬激光碎石术治疗肾结石的临床疗效及安全性.方法 794例肾结石患者按随机数字表法分为对照组和观察组各397例,对照组予体外冲击波碎石进行治疗,观察组以经皮肾镜钬激光碎石术治疗.结果 观察组结石总取净率97.48％,一次取净率87.15％,均高于对照组(x2=14.72、24.78,均P＜0.05)；与对照组比较,观察组手术时间缩短(t=2.36,P＜0.05),出血量减少(=3.27,P ＜0.05),住院时间亦缩短(t=1.28,P＜0.05),并发症发生率低(x2=17.06,P＜0.05).结论 微创经皮肾镜钬激光碎石术治疗肾结石安全有效,并发症少、恢复快,值得临床推广应用.

Objective To investigate the clinical efficacy and safety of kidney stones minimally invasive percutaneous nephrolithotomy holmium laser lithotripsy.Methods 397 cases patients with kidney stones were randomly divided into the control group and the experimental group,the control group were treated with the extracorporeal shock wave lithotripsy treatment,and the later group were treated with holmium laser lithotripsy for percutaneous nephrolithotomy.Results The experimental group of taking the net rate was 97.48％,and the time of taking the net rate was 87.15 ％,higher than those of the control group(x2 =14.72,24.78,all P ＜ 0.05).Compared with the control group,the shortened operation time,(t =2.36,P ＜ 0.05),the reducing amount of bleeding (t =3.27,P ＜ 0.05),the shortened length of stay hospital (t =1.28,P ＜ 0.05),low complication rate (x2 =17.06,P ＜ 0.05) took place in the experimental group.Conclusion Minimally invasive percutaneous nephrolithotomy holmium laser lithotripsy treatment of kidney stones is safe and effective,fewer complications,faster recovery,which is worthy of promotion.
