Acute renal failure is an exceptional condition that befalls when the kidney loses the ability to eradicate salts, waste material and fluid from the blood. Since waste elimination is the core function of the kidney, failure to do so results in body fluids rising to dangerous levels. Acute renal failure is often witnessed by people who are already under medical supervision. The condition can aggravate in a matter of few days to few weeks. It is potentially a life-threatening condition and requires expert medical care under supervision.

Some of the common ones include conditions that slow down the flow of blood to the kidney, kidney gets directly damage, the uterus gets blocked and the waste can t leave the body through the urine etc. Here is more on the causes:
