经皮肾穿刺微造瘘输尿管镜治疗肾结石

目的：探讨经皮肾穿刺微造瘘输尿管镜治疗肾结石的方法及疗效。方法：对30例接受经皮肾穿刺微造瘘输尿管镜下气压弹道碎石取石治疗的。肾结石患者临床资料进行回顾性分析。结果：30例肾结石患者均Ⅰ期手术取石，单通道取石26例，双通道取石4例；其中1次取石28例，2次取石2例。28例结石全部取尽，余2例有少许残留，术后行ESWL，结石基本排出。平均手术时间90min，术后平均住院时间8天，造瘘管平均留置时间6天，术中均未输血，所有病例均无明显并发症。结论：经皮肾穿刺微造瘘输尿管镜治疗肾结石安全、高效，具有对患者创伤小、恢复快、并发症少等优点，值得推广应用。

Treatment of renal calculi with minimally invasive percutaneous nephrolithotomy

Objective： To evaluate the method and efficiency of minimally invasive percutaneous nephrolithotomy in treating renal calculi. Methods：30 patients with renal calculi were managed by minimally invasive PCNL under ureteroscopy and APL lithoclast. Results：All cases underwent one-stage PCNL. 26 eases were treated with single-access PCNL, 4 with two-access PCNL, with one session in 28 cases, tow in 2 cases. The stones in 28 cases were completely removed, and the other 2 cases were treated with ESWL. The average operation time was 90 minutes ,the average hospitalization 8 days, and the mean time of the nephrostomy tube was 6 days. No one needed intraoperative blood transfusion. No obvious complications were observed. Conclusion：Minimally invasive PCNL to renal calculi was claimed to be safe and a high success rate. Minimally invasive PCNL has advantages of less trauma, fewer complications, and quick recovery. It is worthy of widespread applications
