Arrangement of dialysis for kidney failure patients
Dialysis is a type of treatment that helps your body remove extra fluid and waste products from your blood when the kidneys are not able to. Dialysis was first used successfully in the 1940's and became a standard treatment for kidney failure starting in the 1970s.

Acute kidney injury (AKI): a sudden episode of kidney failure or kidney damage that happens within a few hours or days. AKI is usually treated in a hospital setting with intravenous fluids (given through the vein). In severe cases, dialysis may also be needed for a short time until the kidneys get better.

Kidney failure: when 10-15% of your kidney function remains, measured by an estimated glomerular filtration rate (eGFR) of less than 15 mL/mi .
