Acute kidney injury (AKI), is the sudden decrease in kidney function. This can happen over a period of hours, days or, in some cases, weeks. AKI used to be called acute renal failure, but kidney failure doesn't always happen with AKI. Common causes of AKI are dehydration, blood loss, and medicines.
When AKI happens, the kidneys have trouble removing waste and excess fluids from the body. The waste and fluids build up and become harmful.
Kidney function may return to normal if the cause of AKI is treated quickly. Your chance of a full recovery depends on what caused the problem, how quickly the cause was treated, and what other medical problems you have. A machine may be used to help your kidneys remove waste and fluids for a short period of time. This is called dialysis.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
