Kidney failure is sudden loss of the ability of the kidneys to excrete
wastes, concentrate urine, and conserve electrolytes. It is also referred
to as renal failure. The kidneys filter wastes and excrete fluid by using
the bloodstream's own natural pressure. Some of the numerous causes of
damage to the kidneys include:
- Decreased blood flow
- Acute tubular necrosis (ATN)
- Over-exposure to metals, solvents, radiographic
contrast materials, certain antibiotics, and other medications or substances.
- Myoglobin in the urine
- Direct injury to the kidney.
- Infections such as acute pyelonephritis or septicemia.
- Urinary tract obstruction
- Severe acute nephritic syndrome.
- Disorders of the blood
- Autoimmune disorders
