Prerenal Acute Renal Failure
Prerenal acute renal failure (ARF) occurs when a sudden reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of kidney function. In prerenal acute renal failure, there is nothing wrong with the kidney itself.
Prerenal acute renal failure is the most common type of acute renal failure, accounting for about 55 out of 100 acute renal failure cases.1 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 the body.
Causes of prerenal acute renal failure include:
Treatment focuses on correcting the cause of the prerenal acute renal failure. 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 renal failure can cause tissue death in the kidneys and lead to intrinsic (intrarenal) acute renal failure.
