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).

Conditions

Validity; Renal Artery Duplex; Critically Ill Acute Kidney Injury

Outcome Measures

Primary Outcomes (1)

• Renal 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.

  1 week post-procedure

Study Arms (1)

Study group
