摘　　要：目的 分析超声引导下经皮肾镜碎石术建立经皮肾通道过程中出现的困难及原因,探讨提高成功率的技术细节.方法 记录45例超声引导下经皮肾镜碎石术的手术过程,对建立经皮肾通道过程中出现的困难现象进行总结,对困难原因及技术不足进行分析.结果 建立经皮肾通.道过程中发生困难60例次,穿刺/扩张深度为最常见原因,达41.7％（25/60）,18.3％（11/60）为穿刺/扩张方向原因,15.0％（9/60）为集合系统无扩张,13.3％（8/60）为超声观察不清.结论 建立经皮肾通道最常发生穿刺/扩张深度的误差,其次容易出现穿刺/扩张方向的偏离,针对这些问题提高技术细节能够提高手术成功率.Objective To investigate the difficulties of building channel in ultrasound-guided percutaneous nephrolithotomy （PCNL）.Methods Surgical processes of 45 patients underwent PCNL were recorded.The difficulties and causes in building channel were analyzed.Results In the process of building channel in PCNL,60 cases of difficulties happened,41.7％ （25/60） because of depth inaccuracy of puncture and dilation,18.3％（11/60） because of angle deviation of tract dilation,15.0％（9/60） result from nondilated collecting system,13.3％（8/60） because of lacking experience in ultrasound observation.Conclusions The most often encountered difficulties is depth inaccuracy of puncture and dilation in building channel,next is angle deviation of tract dilation.To improve technique detailes is the key to gain success.
