Acute renal (kidney) failurecan be triggered by a variety of medical conditions that damage the kidneys.
Common Causes
Usually, the kidneys can continue to function well, even when you become sick.
Acute kidney failure is a consequence of severe and rapid damage to the kidneys.

Verywell
It may be reversible or it could be permanent, resulting in lasting kidney dysfunction.
Toxins
Medications contain components that must pass through the kidneys as they are processed in the body.
Some of these chemicals can induce toxic damage to the kidneys, causing them to fail.
Post Surgery
Acute renal failure can develop in the first few days after surgery.
Urine output is anothermeasure of acute renal failure.
Most people who experience acute renal failure after surgery will improve within a few weeks.
If you experience acute renal failure after surgery, you may needdialysis.
Usually, kidney function improves over time, and dialysis is not typically necessary for the long term.
Acute renal failure is the consequence.
Glomerulonephritis
Glomerulonephritis is inflammation of the kidneys and generally occurs slowly, causing progressive kidney damage.
The inflammation affects the kidneys over time, causing progressive, rather than acute renal failure.
The gradual kidney failure can produce sudden symptoms and may suddenly become noticeable over a short period of time.
Blood clots can also affect the kidneys.
When these events occur rapidly, they cause sudden kidney damage, resulting in acute renal failure.
A severe lack of blood flow and oxygen supply may cause acute renal failure.
This includes those that supply the kidneys.
Vascular disease generally causes a slow progression of kidney failure, rather than acute renal failure.
Lifestyle
In general, lifestyle issues are not a leading cause of acute renal failure.
But, there are some lifestyle factors that can increase your chances of developing the condition.
Heavy Alcohol Use
Heavyalcohol use damages the livermore than it targets the kidneys.
Kidney failure due to alcohol is a slow process.
Like other gradual causes, the effects may suddenly become noticeable and appear as acute renal failure.
Analgesic Overuse
Several over-the-counter pain medications maycause acute renal failure, especially with excessive or chronic use.
Blood flow to the kidneys can be affected by circulatory problems in any part of the body.
Blood flow to the kidneys can be indirectly affected byliver cirrhosisandliver failure.
This can lead to punch in 1hepatorenal syndrome, a life-threatening condition that ultimately requires aliver transplant.
Sepsisoccurs when the immune systems response to an infection causes damage to tissues.
This can lead to multi-organ failure, including acute intrinsic kidney failure.
Every drug you take passes through the kidneys to some degree.
