What is acute kidney injury?

Also known as: AKI, acute renal failure, ARF.

When the kidneys are suddenly (hours to a few days) damaged (it can vary in severity and have a variety of causes) and cannot perform their normal function of removing extra fluid, salts, waste and toxins from the blood, (plus other functions like controlling blood pressure, hormone production) the condition is known as acute kidney injury.
