Acute Kidney Injury (AKI) is seen in 15% of hospitalized patients and a renal ultrasound (RUS) is often ordered to exclude an obstructive cause in the initial evaluation of AKI. This study was done to evaluate the usefulness of a RUS in patients with AKI in a developing country.
We thus recommend doing a renal ultrasound in all cases of AKI due to the fact that most of the time in a developing country, an accurate history is not available, and the prevalence of stone disease and obstructive uropathy is high.
