目的探讨微创经皮肾镜取石术(min-PCNL)治疗肾盏憩室结石的安全性及有效性。方法对接受微创经皮肾镜取石术治疗的8例肾盏憩室并肾结石患者的临床资料进行回顾性分析。结果所有患者均行一期单通道穿刺取石。术中利用钬激光烧灼肾盏憩室开口。肾造瘘管平均留置时间5d,平均住院时间8d。其中1例min-PCNL术中改开放手术、输血。有1例憩室结石复发。无其他重大并发症。结论微创经皮肾镜取石术治疗肾盏憩室结石安全,可行,疗效确切,但要注意适应证的选择(肾盏憩室位于中下极)。与开放手术相比,能减少术中、术后出血及并发症。具有创伤小、恢复快、可反复操作等优点。
Objective To investigate the safety and efficacy of minimally invasive percutaneous nephrolithotomy (min-PCNL) in the treatment of calyceal diverticula calculus. Methods The clinical data of 8 patients with calyceal diverticulum and nephrolithiasis underwent minimally invasive percutaneous nephrolithotomy were retrospectively analyzed. Results All patients underwent a single-pass puncture. Intraoperative use of holmium laser burn calyceal diverticulum openings. Renal fistula average retention time 5d, the average length of stay 8d. One case of min-PCNL surgery to open surgery, blood transfusions. One case of diverticulum stones recurrence. No other major complications. Conclusions Minimally invasive percutaneous nephrolithotomy lithotripsy for calyceal diverticulum stones is safe, feasible and effective, but should pay attention to the choice of indications (calyceal diverticulum located in the middle and lower pole). Compared with open surgery, can reduce intraoperative and postoperative bleeding and complications. With trauma, rapid recovery, can be repeated operation and so on.
