超声引导下经皮肾镜取石术肾脏通道的建立与应用

目的 评估在超声引导下建立经皮肾镜取石术（PNL）肾脏通道的方法及效果。方法在超声引导下对上尿路结石患者建立经皮肾镜工作通道后，行碎石取石术。结果35例均能准确进入肾盏目标位置，建立取石通道。16例患者一次取净。7例症状不明显的残余结石，PNL术后自然排出体外，12例需要其它辅助方式治疗，手术平均时间158min，无工作通道建立过程中常见的严重并发症发生。结论超声引导穿刺可以为PNL提供安全、准确的工作通道，对PNL有重要的临床应用价值。

Clinical application of establishing renal channel in Percutaneous nephrolithotomy with ultrasound-guided

Objective To evaluate the feasibility and availability of establishing renal channel in Percutaneous nephrolithotomy with ultrasound - guided. Methods Mter the renal channels of 35 patients suffering from renal calculi and up - per ureteral calculi were established under the guide of ultrasound, they were treated with PNL. Results In this group, all cases were punctured successfully and optimal working channels were established. 16 patients were primarily stone - free, 7 patients had clinically insignificant residual stones that passed spontaneously after PNL, and 12 patients needed auxiliary measures. Average operative duration was 158 minutes. No major complications were discovered. Conclusion The working channel established under the guide of ultrasound is safe and exact in PNL. It is of great value of clinical application for PNL.
