Unfortunately this leads to imbalanced levels of waste accumulated in the blood, making this a very serious problem. This condition can be fatal and requires intensive treatment. Fortunately, however, this may be reversible. Prerenal kidney failure occurs suddenly when a reduction in blood flow to the kidneys causes loss of kidney function. Prerenal renal failure is the most common type of acute renal failure. This complication is the product of many diseases, conditions, and medications that reduce the normal amount of fluid and blood, especially in the body. Some examples of these drugs are ACE inhibitors and NSAIDs, severe dehydration and burns. Another type of renal failure is intrarenal. This condition occurs when direct damage to the kidneys causes a sudden loss of kidney function. Acute tubular nerosis is a very common cause of intrarenal renal failure, a condition in which the small filtering tubes of the kidney become damaged. Other causes are complicated surgeries ACUTE KIDNEY FAILURE 3 (cardiovascular or abdominal), severe b...... middle of sheet ......
