acute kidney injury (AKI), (which used to be called acute renal failure), occurs when a sudden
reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of
kidney function. In prerenal acute kidney injury, there is nothing wrong with
the kidney itself.
Prerenal acute kidney injury is the most common type of acute kidney injury. It can be a complication of almost any disease, condition, or
medicine that causes a decrease in the normal amount of blood and fluid in
Causes of prerenal acute kidney injury include:
Treatment focuses on correcting the cause of the prerenal acute kidney injury. Depending on the cause, the condition often reverses itself within a
couple of days after normal blood flow to the kidneys has been restored.
But if it is not reversed or treated successfully and quickly, prerenal
acute kidney injury can cause tissue death in the kidneys and lead to intrinsic
(intrarenal) acute kidney injury.
