Normally, the kidneys filter the blood and remove waste and excess salt and water. Acute kidney failure is when the kidneys suddenly stop working. Acute renal failure can be due to many different causes. Generally these causes can be divided into three categories. Pre-renal means the cause is before the kidney or glomerulus.
