为探寻一种预测肾积水肾功能恢复的方法,应用一侧可复性输尿管部分梗阻模型,利用高分辨彩色多普勒显像(CDFI)测定肾动脉血流频谱,分析阻力指数(RI)在肾积水肾功能可复性预测中的价值。结果显示:RI对预测肾功能的可复性有较好的指导作用,当RI<0.7,肾功能正常;0.7<RI<0.8,肾功能可部分或完全恢复;当RI>0.8,肾功能不能恢复。RI还可用于肾积水的术后随访。认为CDFI可预测肾积水肾功能恢复情况,为临床选择治疗方法提供可靠依据。
In order to explore a method of predicting renal function recovery of hydronephrosis, the renal refraction index (RI) was analyzed by using one-sided refolding ureteral obstruction model and high-resolution color Doppler imaging (CDFI) The value of renal function refolding in hydronephrosis. The results showed that: RI is a good guide for predicting the refolding of renal function. When RI <0.7, normal renal function, 0.7 0.8, renal function can not be restored. RI can also be used for postoperative follow-up of hydronephrosis. That CDFI can predict the recovery of renal hydronephrosis, to provide a reliable basis for clinical choice of treatment.
