Abstract Objective: To evaluate how fistulation affect the renal blood flow in hydronephrotic patients by color Doppler. To explore the clinical significance of recovering renal function. Method: Fifty-three patients with 67 hydronephrosis were collected. All of them were taken the color Doppler test of resistent index(RI) of kidney artery, renal parenchyma before and after fistulation. The correlation between RI and the thickness of renal parenchyma were analyzed. Result: RI and the thickenss of the three groups had statistical significance. There was correlation between the renal function and the thickness of renal parenchyma. When the thickness of renal parenchyma was less than 3mm or RI>0.81, the sensitivity to evaluate the irreversibility was 90.5% and the specificity was 96.0%. Conclusion: When the thickness of renal parenchyma was less than 3mm or RI>0.81, it can be used as an clinical marker to evaluate the reversibility for it can reflect how the renal function were injured and how the renal blood flow changed.
