Medical Technology: Kidney Dialysis

Year 8 Science

National Kidney Foundation

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.

This Action Plan aims to provide a blueprint for transforming kidney disease in Australia over the next 10 ten years with over 30 actions across 3 priority areas designed to address the most pressing needs in kidney disease.

Dialysis is a treatment for individuals whose kidneys are failing. There are two types of dialysis, hemodialysis and peritoneal dialysis, that both perform normal kidney functions, filtering waste and excess fluid from the blood.


Lifesaver dialysis: More than 3 million people worldwide need to regularly undergo this vital blood-cleansing procedure. When kidneys fail, dialysis takes over and performs their most important functions, removing waste products, toxins, and excessive salt and fluids from the patient’s body.

Hemodialysis is the process of cleaning the patient’s blood outside the body. Learn more about this renal replacement therapy option.


CKD (Chronic Kidney Disease) is mostly diagnosed at more advanced stages when symptoms become more apparent. Kidney failure occurs when the kidneys can no longer function adequately, at which point people require kidney replacement therapy (KRT) – a kidney transplant or dialysis – to survive.


The artificial kidney, or hemodialyzer, is a machine that provides a means for removing certain undesirable substances from the blood or of adding needed components to it.

A type of low-carb, high-fat diet that's typically used to manage seizures for children with epilepsy could reverse kidney disease in Type 1 and Type 2 diabetics, a new animal study suggests.

If successful in humans, the so-called ketogenic diet could have the potential to replace dialysis, which is a procedure that artificially filters blood in place of a damaged or failed kidney.
