微通道经皮肾输尿管镜钬激光碎石术治疗复杂性输尿管上段结石

The safety and efficacy of ultrasound-guided minimally invasive percutaneous nephrolithotomy for the patients with complicated upper ureteral calculus

目的探讨超声引导下微通道经皮肾输尿管镜钬激光碎石术治疗复杂性输尿管上段结石的有效性和安全性。方法回顾性总结超声引导下微通道经皮肾输尿管镜钬激光碎石术治疗复杂性输尿管上段结石48例临床资料,分析手术时间、结石清除率、拔管时间、术后平均住院日、手术并发症等指标。结果 48例均I期成功建立16F皮肾通道并成功碎石,平均手术时间24min,估计平均出血量60ml。术后复查超声、KUB,一次结石清除率100%,无大出血,无胸膜、结肠损伤等并发症。结论超声引导下微通道经皮肾输尿管镜钬激光碎石术是一种治疗复杂性输尿管上段结石比较安全、有效的方式。

Objective The purpose of the study was to evaluate the safety and efficacy of ultra- sound-guided minimally invasive percutaneous nephrolithotomy （mini-PCNL） for the patients with compli- cated upper ureteral calculus. Methods The clinical data of forty-eight patients with complicated upper ureteral calculus was retrospectively analyzed, all of the patients had undergone uhrasound-guided mini- PCNL. The parameters include operative time, the stone-free rate, the retention time of nephrostomy tube, the average postoperative hospital stay and the complications. Results In all the 48 cases, the 16F nephrostomy tract was established and the calculus were cleared successfully in one stage. The average op- erative time was 24 minutes, the average estimate intraoperative blood loss was 60ml. The stone-free rate is 100% according to the uhrasonography or KUB after the surgery. There were no complications such as bleeding, the damage to pleura or intestines. Conclusions As the preferred treatment of complicated upper ureteral calculus, ultrasound-guided mini-PCNL is a safe and effective procedure.
