Acute Renal Failure

Postrenal Acute Renal Failure

Acute renal failure (acute kidney injury) occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance.

It is not as common as intrinsic acute kidney injury (AKI) or acute tubular necrosis (ATN).
