Comparative Evaluation of Changes in Renal Blood Flow in Different Types of Acute Kidney Injury
This article presents data of Doppler examination of the kidneys in patients with different types of acute kidney injury (AKI) under oligoanuria and diuresis restoration. In all patients at baseline, at admission we revealed impaired renal hemodynamics, severity of which was different depending on the type of AKI. During the treatment, at diuresis restoration, renal blood flow parameters improved. Speed and completeness of hemodynamics recovery were defined both by type (etiology) and the severity of renal damage. With the transformation of AKI into chronic renal failure, blood flow velocity remained low, resistive index did not decrease even when diuresis and nitrogen excretion renal function restored.
