Sonographic Venous Doppler Imaging in Acute Kidney Injury

Diagnostic Accuracy of Sonographic Venous Doppler Imaging in Acute Kidney Injury

The first presentations of patients with acute kidney injury (AKI) are usually to the emergency departments. While the mortality rate is 5-10% in uncomplicated AKI, it is between 40-90% in patients hospitalized in the intensive care unit. Therefore early diagnosis and treatment of AKI in the emergency department is important in terms of morbidity and mortality.

Sonographic evaluation of the venous system (hepatic, portal and renal vein) may be useful for diagnosis. Studies conducted so far have generally been based on predicting cardiorenal AKI and renal poor outcomes and have been designed in general ICU conditions.

In this study, the investigators aimed to determine the diagnostic value of sonographic venous Doppler imaging in terms of distinguishing subgroups of AKI in patients presented to the emergency department with AKI.

Inclusion Criteria:

• AKI diagnosis

Exclusion Criteria:

Patients

• with end-stage renal failure (stage 4),
• who received 500 mL IV fluid or 40 mg diuretics,
• who are pregnant,
• with renal transplantation,
• with cirrhosis and liver malignancy,
• with postrenal AKI,
• who were referred from another center after starting treatment,
• who do not give consent for the study.
