补充性体外冲击碎石术治疗钬激光碎石术后残余结石

Complementary ESWL treatment for residual stones after holmium laser lithotripsy

目的探讨补充性体外冲击碎石(ESWL)术治疗钬激光碎石术后残余结石的临床疗效和治疗价值。方法 2006年1月至2009年10月,上海市嘉定区中心医院对输尿管镜下钬激光碎石术中发生结石漂移或术后存在≥6 mm残余结石的86例患者进行了补充性ESWL术,取得了满意的疗效。结果 78例(90.6%)患者ESWL后B超下观察碎石成功,2个月后B超和腹部平片+静脉肾盂造影证实无残余结石;8例(9.4%)患者仍存在≤5 mm残余结石。结论补充性ESWL术是治疗输尿管镜下钬激光碎石术出现残余结石和结石漂移的主要选择之一,可明显提高结石排尽率。

Objective To investigate the clinical efficacy and therapeutic value of complementary ESWL treatment for residu- al stones after holmium laser lithotripsy. Methods From January 2006 to October 2009, 86 cases who happened stone drift dur- ing holmium laser lithotripsy under ureteroscopic or had residual stones which I〉6 mm in Jiading district central hospital were un- derwent complementary ESWL procedure, and the effect was satisfactory. Results Seventy-eight eases （ 90. 6% ） after ESWL were successful observed by B ultrasound. Two months later, B ultrasound and KUB ＋ IVP confirmed that therer was no residual stone. Eight eases （9.4%） remained ≤ 5 mm residual stones. Conclusion Complementary ESWL procedure is the main choice in treating residual stones and stone drifting occured after complementary ureteroscopic holmium laser lithotripsy. It can improve the stone free rate.
