Renal Doppler ultrasound to predict acute kidney injury in critically ill patients with acute circulatory failure
Authors' conclusion
To conclude, renal Doppler parameters (RRI, PDU, and RRI/PDU) on day 1 through day 3 can predict the development of AKI by day 5 in critically ill adults with acute circulatory failure.
