Critically Ill Acute Kidney Injury, Renal Artery Duplex, Validity

Brief summary

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).

Detailed 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.

Interventions

OTHERRenal Artery Duplex

Renal artery duplex will be performed to all patients in terms of renal resistivity index (RRI).
