彩超引导建立经皮肾镜钬激光碎石术前通道的临床应用价值

目的：探讨彩超引导下建立经皮肾镜术前通道在微创经皮肾穿刺取石术（minimally invasive percutaneous nephrolithotomy，MPCNL）中的临床应用价值，并评价其安全性及疗效。方法：选取2012年1月-2014年4月本院收治的91例上尿路结石患者，在彩超引导下根据结石的具体分布情况选择穿刺点并建立术前工作通道，行经皮肾镜联合钬激光碎石取石术，观察其疗效。结果：本组91例患者在彩超引导下均一次性穿刺成功，成功建立经皮肾盂通道，无大出血等并发症产生。结论：采用彩超引导穿刺建立经皮肾镜工作通道成功率高，创伤小，安全性好，具有较高的临床应用价值。

Clinical Application Value of Establishing Renal Channel in Percutaneous Nephrolithotomy with Holmium laser Under Ultrasound-guided

Objective：To discuss the clinical application value of establishing renal channel in minimally invasive percutaneous nephrolithotomy（MPCNL）with ultrasound-guided,and to evaluate the safety and feasibility.Method：91 patients with upper urinary tract calculus in our hospital from January 2012 to April 2014 were selected,they were treated with MPCNL with holmium laser,puncture points were selected and then channels were established under ultrasound-guided according to the distributions of calculi before MPCNL,and the effect was observed.Result：Reliable percutaneous access into the pelvicaliceal system was established successfully in all 91 patients under ultrasound-guided.No massive hemorrhage or other severe complications occurred.Conclusion：Establishing channel under ultrasound-guided in MPCNL is safe and minimally invasive with a high success rate.It has high value in clinical application.
