目的：使用彩色多普勒超声评估微创经皮肾镜取石术对肾血流灌注的影响。方法：选择行微创经皮肾镜取石术的62例患者为研究对象，观察其肾动脉血流彩色多普勒超声表现，分析和比较手术前后收缩期峰值流速（PSV）、舒张末期流速（EDV）及阻力指数（RI）等参数的变化情况。结果：与术前相比，术后肾叶间动脉、段动脉PSV、EDV明显较高，差异有统计学意义（P＜0.05），术后RI比较差异无统计学意义（P＞0.05）；术后肾主动脉远心端PSV、EDV与术前比较差异无统计学意义（P＞0.05），RI明显低于术前，差异有统计学意义（P＜0.05），肾主动脉近心端PSV、EDV、RI与术前比较差异无统计学意义（P＞0.05）。结论：微创经皮肾镜取石术能明显改善肾内血流灌注，彩色多普勒超声是评估其改善情况的敏感指标，在制定治疗方案、评估疗效等方面具有重要的临床意义。

Objective Using color doppler ultrasound assessment of minimally invasive percutaneous nephrolithotomy on renal perfusion. Methods 62 cases of percutaneous nephrolithotomy minimally invasive patients as the research object,observethe renal artery hemodynamics with color Doppler ultrasonography before and after operation,the analysis and comparison of the peak systolic velocity(PSV),end diastolic velocity(EDV) and resistance index(RI) changes in parameters such as.Results Compared with the preoperative,postoperative renal leaf and segmental artery between PSV and EDV significantly higher,statistically significant difference(P<0.05),postoperative RI comparative difference was not significant,no statistical significance(P>0.05);Postoperative renal aorta telecentric side PSV,EDV compared with preoperative no significant difference(P>0.05),and RI were significantly lower than the preoperative,statistically significant difference(P<0.05),renal near heart aorta PSV,EDV,RI were no obvious difference compared with preoperative,no statistical significance(P>0.05).Conclusion Minimally invasive percutaneous nephrolithotomy can significantly improve renal blood perfusion,color doppler ultrasound is sensitive index for evaluate the improvement,in making treatment plan,evaluation of curative effect and so on has important clinical significance.
