Dialysis is a treatment that replaces some kidney function by removing excess waste and build up in the body.

There are different types of dialysis:

Hemodialysis (HD) is a medical treatment where blood is removed from the body and filtered through a machine to remove waste, toxins and fluids.     

There are different kinds of hemodialysis:

In-Center Hemodialysis

The patient goes to a dialysis clinic three times every week to connect to a dialysis machine for 3-5 hours per session.

Home Hemodialysis

The patient and caregiver(s) are trained to safely perform dialysis treatments at home throughout the day or at night.

Peritoneal dialysis (PD) is a treatment where the inside lining of the belly acts as a filter to remove waste from the body.  A fluid called dialysate is put into the belly through a permanent catheter.  The fluid is left inside the body for a period of time, pulling waste through the belly lining.  Then the fluid is removed through the catheter again and disposed of.  This process is called an exchange.


There are different kinds of peritoneal dialysis:

Continuous Ambulatory Peritoneal Dialysis

This is the most common type of peritoneal dialysis. The patient does 4-6 exchanges throughout the day in a clean room.

Continuous Cycling Peritoneal Dialysis

The patient does exchanges at night while the patient sleeps using a machine called a "cycler."
