Overview
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
- Other Renal Artery Duplex
Renal artery duplex will be performed to all patients in terms of renal resistivity index (RRI).
Primary outcome measures
- Renal resistivity index (RRI) [Time frame: 1 week post-procedure]
Eligibility criteria
Inclusion criteria
- Patients age >18 years.
- Both sexes.
- Patients within 24 hours after intensive care unit (ICU) admission.
Exclusion criteria
- Patients presented with poor abdominal echogenicity.
- Chronic kidney disease, especially with estimated creatinine clearance less than 30 ml/min/1.73m.
- Patients with dialysis dependency.
- Patients with renal transplantation.
- Patients with known renal artery stenosis.
- If there is a pregnancy.
- Patients with any congenital kidney diseases as mono-kidney, anatomic kidney abnormalities.
