About

This study aims to assess the clinical relevance of renal artery duplex ultrasound in critically ill patients with acute kidney injury (AKI) in terms of the renal resistive index (RRI).

Full description

Diagnosis of acute kidney injury (AKI) is based on rising creatinine as late phenomenon. Intrarenal vasoconstriction occurs earlier, so measuring flow resistance in the renal circulation, renal resistive index (RRI), could become part of vital organ function assessment using Doppler ultrasound.
