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).
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.

RECRUITINGRenal resistivity index (RRI)
The renal resistivity index (RRI) will be assessed in patients with acute kidney injury (AKI) who require intensive care unit (ICU) admission within 24 hours.
