微创经皮肾镜钬激光碎石术治疗上尿路结石

Treatment of Upper Urinary Calculi with Ho:YAG Laser Lithotripter by Minimally Invasive Percutaneous Nephrolithotomy

目的:探讨微创经皮肾镜钬激光碎石术治疗上尿路结石的临床疗效。方法:应用钬激光经皮肾穿刺微造瘘对31例肾结石,11例输尿管上段结石患者实施治疗。结果:肾结石一期粉碎排净23例,输尿管结石均一期排净。结石一期粉碎排净率81%(34/42),患者术后均恢复顺利,无严重并发症。结论:微创经皮肾镜钬激光碎石术是治疗肾及输尿管上段结石的有效方法。

Objective： To investigate the clinical outcomes of Ho：YAG laser lithotripter with minimally invasive percutaneous mephrolithotomy in upper urinary calculi treatment . Methods：Totally 11 cases of patients with upper ureteral calculi and 31 cases of renal calculi patients were treated with Ho：YAG laser lithotripter by minimally invasive percutaneous nephrolithotomy. Result：All the upper ureteral calculi patients achieved stone-free at 1 session. Of 31 cases with renal calculi, 25 achieved stone free at 1 session. The overall successful stone fragmentation rate with stone-free expectoration of the ureteral and renal calculi was 81% （34/42）. All the patients recovered well postoperatively and no major complications observed. Conclusions：The technique of Ho：YAG laser lithotripter with minimally invasive percutaneous nephrolithotomy is safe and effective for the treatment of upper urinary calculi.
