Causes
By Mayo Clinic staffAcute kidney failure occurs when your kidneys suddenly become unable to filter wastes from your blood. Acute kidney failure can occur when something damages your kidneys, or it can occur when another condition slows blood flow to your kidneys. Acute kidney failure can also occur when the wastes filtered by your kidneys aren't able to leave your body through your urine.
Diseases and conditions that slow blood flow to the kidneys
Diseases and conditions that may slow blood flow to the kidneys and can lead to kidney failure include:
- Blood loss
- Blood pressure medications
- Heart attack
- Heart disease
- Infection
- Liver cirrhosis
- Nonsteroidal anti-inflammatory drugs, such as aspirin, ibuprofen and naproxen
- Severe allergic reaction (anaphylaxis)
- Severe burns
- Severe dehydration
Diseases and conditions that may damage the kidneys
These diseases, conditions and agents may damage the kidneys and lead to acute kidney failure:
- Blood clots in the veins and arteries in and around the kidneys
- Cholesterol deposits that block blood flow in the kidneys
- Glomerulonephritis
- Hemolytic uremic syndrome
- Infection
- Lupus
- Medications, such as certain chemotherapy drugs, antibiotics, dyes used during imaging tests and zoledronic acid (Reclast, Zometa), used to treat osteoporosis and elevated blood calcium levels (hypercalcemia)
- Multiple myeloma
- Scleroderma
- Thrombotic thrombocytopenic purpura
- Toxins, such as alcohol, heavy metals and cocaine
