目的:探讨微造瘘经皮肾穿刺取石术(mPCNL)治疗肾及输尿管上段结石的疗效。方法:采用mPCNL治疗24例肾及输尿管上段结石患者,结石长径1.8~3.0 cm,单发性结石16例,多发性结石8例,其中鹿角形结石4例;肾结石20例,输尿管上段结石4例。结果:21例行一期穿刺取石,3例因合并脓肾行二期取石,结石清除率95.8%,手术平均时间2 h,术中及术后均无明显出血。结论:mPCNL是一种有效的治疗肾及输尿管上段结石的方法,创伤小,恢复时间短。
Objective: To investigate the effect of percutaneous nephrolithotomy (mPCNL) in the treatment of renal and upper ureteral calculi. Methods: Twenty-four patients with renal and upper ureteral calculi under mPCNL were treated with mPCNL. The long diameter of the stone was 1.8-3.0 cm, the solitary stone was 16, the multiple stone was 8, the antler was 4, the renal stone was 20, the upper ureteral calculi 4 cases. Results: Twenty-one patients underwent primary puncture and stone removal. Three patients had secondary stone removal due to complicated pyrimonosis. The stone clearance rate was 95.8%. The mean operation time was 2 h. There was no obvious bleeding during and after operation. Conclusion: mPCNL is an effective method for the treatment of renal and upper ureteral calculi, with less trauma and shorter recovery time.
