两种不同能量钬激光在治疗输尿管上段结石中的临床效果对比

Comparison of clinical effect of two different energy holmium laser in the treatment of upper ureteral calculi

目的 探讨比较两种不同能量钬激光在治疗输尿管上段结石中的临床效果.方法 选择于2010年1月～2012年5月分别采用60W钬激光和40W钬激光碎石术治疗输尿管上段结石患者（各63例）,并比较两种不同能量钬激光碎石术在治疗输尿管上段结石的临床疗效.结果 40W钬激光组患者的结石清除率明显高于60W钬激光组,且差异具有统计学意义（X2=5.24,P＜0.05）.而两组患者的手术时间及平均住院时间比较则无明显差异（t =0.76、0.65,P＞0.05）.结论 对于输尿管上段结石,使用经皮肾镜碎石术治疗时,使用能量较小的激光,碎石成功率更高,可以有效提高碎石率,减少患者术后再次处理的风险.

Objectives To investigate the clinical effect of two different energy holmium laser in the treatment of upper ureteral calculi.Methods This study in 2010 January 2012 year in May by 60 W and 40 W holmium：YAG laser lithotripsy holmium：YAG laser lithotripsy for upper ureteral calculi,and compare the two kinds of different energy holmium laser lithotripsy in treatment of ureteral calculi.Results 40 w holmium laser were stone -free rate was higher than 60 who：YAG laser group,and the difference was statistically significant （x2 =5.24,P＜ 0.05）.But the operation time of two groups of patients and the average hospitalization time compared with no significant difference （t =0.76,0.65,P ＞ 0.05）.Conclusions For the upper ureteral calculi,using percutaneous nephrolithotomy treatment,laser energy is smaller,the successful rate of lithotripsy is higher,can effectively improve the aggregate rate,reduce postoperative treatment risk again.
