Abstract：Objective To investigate the diagnostic significance of color Doppler ultrasonography for detecting renal artery hemodynamics of hypertension.Methods The patients with hypertension were chosen as observation group (n=96) and the objects with physical examinations were chosen as control group (n=98) from the Department of Ultrasonography of Sixth People’s Hospital of Kunshan City in Jiangsu Province. All objects were given the detections of color Doppler ultrasonography, and some indexes including renal length, renal parenchymal thickness, thickness of renal sinus and ratio of parenchymal thickness to sinus thickness, and hemodynamic parameters of middle segment of sinus renal artery (SRA) and segment of interlobular renal artery (IRA) at cortex-medulla junction were compared in 2 groups.Results The indexes of renal length, renal parenchymal thickness, thickness of renal sinus and ratio of parenchymal thickness to sinus thickness were all higher in observation group than those in control group (P<0.05). The maximum systolic flow velocity (Vmax), minimum diastolic flow velocity (Vmin) and resistance index (RI) were all lower in observation group than those in control group (P<0.05). The values of Vmax, Vmin and RI of IRA were all lower in observation group than those in control group (P<0.05).Conclusion Color Doppler ultrasonography can be used for detecting hemodynamic parameters of hypertensive renal arteries, which can reflect the changes in secondary renal perfusion and provide important evidence in diagnosis of early renal damage in patients with hypertension.
