- Dialysis of the kidney
- Is the artificial process of eliminating waste (diffusion), and unwanted water (unfiltration) from the blood.
- Dialysis is necessary as blood is filtered each day, we could live if waste products are not removed from the body.
- Two types of dialysis.
- Hemodialysis
- Blood goes through, and goes through a machine that filters the blood and into the catheter which is inserted into the vein, which is inserted into an artificial kidney.
- Usually takes 3-4 hours, but the duration of each session depends on how well the patients kidney works.

- Peritoneal dialysis.
- A sterile (dialysate) solution rich in minerals and glucose is run through a tube into the peritoneal cavity, the abdominal body cavity around the intestine, where the peritoneal membrane acts as a semi-permeable membrane.
- Two principles:
- 1. Continuous ambulatory peritoneal dialysis (CAPD): Which does not require any machinery which is done by the patient or caregiver.
- 2. Continuous cylic peritoneal dialysis (CCPD): A machine does the dialysis exchange, generally done at night whilst the patient is sleeping.

- Hemodialysis
- When your kidneys fail, dialysis keeps your body in balance by:
- 1. Removing waste, salt and extra water to avoid them building up in the body.
- 2. Keeping a safe level of certain chemicals in your blood e.g. potassium.
- 3. Helping to control blood pressure.
