Five Types of Kidney Failure

There are five different types of kidney failure:

1. Acute Prerenal Kidney Failure

Insufficient blood flow to the kidneys can cause acute prerenal kidney failure. The kidneys can’t filter toxins from the blood without enough blood flow. This type of kidney failure can usually be cured once the cause of the decreased blood flow is determined.

2. Acute Intrinsic Kidney Failure

Acute intrinsic kidney failure can be caused by direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys. Ischemia may be caused by:

• severe bleeding
• shock
• renal blood vessel obstruction
• glomerulonephritis:- which is an inflammation of the tiny filters in your kidneys

3. Chronic Prerenal Kidney Failure

When there isn’t enough blood flowing to the kidneys for an extended period of time, the kidneys begin to shrink and lose the ability to function.

4. Chronic Intrinsic Kidney Failure

This happens when there is long-term damage to the kidneys due to intrinsic kidney disease. Intrinsic kidney disease is caused by a direct trauma to the kidneys, such as severe bleeding or a lack of oxygen.

Chronic Post-Renal Kidney Failure

A long-term blockage of the urinary tract prevents urination, which causes pressure and eventual kidney damage.
