Acute kidney failure is the rapid loss your kidneys' ability to remove waste and help balance fluids and electrolytes in your body. In this case, rapid means less than 2 days.
Acute kidney failure, also called acute renal failure or acute kidney injury develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care.
Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal kidney function.
