Acute kidney injury, also called acute renal failure, is the
sudden loss of kidney function. When acute kidney injury occurs, the kidneys are unable
to remove waste products and excess fluids, which then build up in the body and upset
the body's normal chemical balance.
The most common causes of acute kidney injury
are dehydration, blood loss from major surgery or injury, or medicines such as nonsteroidal
anti-inflammatory drugs (NSAIDs), antibiotics, or the dyes (contrast agents) used
in X-ray tests.
Symptoms depend on the cause of the problem and can include:
or no urine output.
Dizziness upon standing.
of the legs and feet.
Loss of appetite, nausea, and vomiting.
confused, anxious and restless, or sleepy.
Pain in the flank, which is felt
just below the rib cage and above the waist on one or both sides of the back.
treatment of acute kidney injury includes correcting the cause and supporting the
kidneys with dialysis until proper functioning is restored. Most people who develop
acute kidney injury are already in the hospital.
