Acute renal failure is a syndrome caused by many causes, which can be extra-renal or renal, causing temporary and acute collapse and loss of function of both kidneys, due to rapid cessation or decrease in glomerular filtration rate.

Acute renal failure is a dangerous disease. There are many causes of acute renal failure. These causes are divided into: Pre-renal causes of acute renal failure, intra-renal causes of renal failure, and post-renal causes of renal failure.

Hypertension and kidney disease are two closely linked disease states, persistent hypertension can lead to deterioration of kidney function and deterioration of kidney function can lead to deterioration of blood pressure control.

Acute kidney failure occurs when the kidneys lose their ability to filter waste products from the blood, causing toxic substances to build up and causing an imbalance in blood chemistry. Acute kidney failure is common in people being treated in the hospital, especially those who are seriously ill and need special care. Acute kidney failure can be fatal and requires intensive treatment.

High blood pressure can cause kidney failure and vice versa, kidney failure can cause high blood pressure. Because of the relationship, patients with kidney failure need to be treated to prevent high blood pressure, just as people with high blood pressure need to be controlled to avoid dangerous complications of chronic kidney failure.
