目的:探讨标准通道经皮肾镜碎石清石术(PCNL)对肾内血流动力学影响。方法:应用彩色多普勒血流显像测量100例采用标准通道经皮肾镜碎石清石术患者术前、术后即时、术后1周、术后3个月肾脏主动脉、段间动脉、叶间动脉收缩期峰值流速(V_(max))及收缩期峰值(S)与舒张期末流速(D)的比值(S/D)和阻力指数(resistant index,RI)。结果:术后即时的肾主动脉、段间动脉、叶间动脉的V_(max)、S/D、RI值与术前比较,均P<0.05,差异有统计学意义;但术后1周的肾主动脉、段间动脉、叶间动脉的V_(max)、S/D、RI值与术前比较,均P<0.05;并且术后3个月的肾主动脉、段间动脉、叶间动脉的RI值与术前比较,均P<0.05。结论:标准通道经皮肾镜碎石清石术对肾脏血流灌注有短暂影响,但术后1周左右可以恢复,术后3个月肾脏血流灌注有所改善。
Objective: To investigate the effect of standard channel percutaneous nephrolithotomy (PCNL) on intrarenal hemodynamics. Methods: 100 cases of percutaneous nephrolithotomy using standard channel percutaneous nephrolithotomy were measured preoperatively, immediately after operation, 1 week after operation, 3 months after operation, Arterial and interlobar artery peak systolic velocity (V_ (max)) and systolic peak (S) and end diastolic velocity (D) ratio (S / D) and resistance index (RI). Results: The V max, S / D and RI of the immediately postoperative renal aorta, inter-segmental arteries and interlobar arteries were all significantly lower than those before surgery (P <0.05), but the difference was statistically significant Of V_ (max), S / D, RI of renal artery, interstitial artery and interlobar artery were all significantly lower than those before operation, both P <0.05; and renal artery, interphase artery, The RI value of inter-arteries was compared with those before operation, both P <0.05. Conclusion: The standard channel percutaneous nephrolithotomy lithotripsy has a transient effect on the renal perfusion, but it can be recovered about 1 week after operation. The renal blood perfusion is improved at 3 months.
