Peritoneal dialysis uses a membrane
inside your body (peritoneal membrane) as a filter to clear wastes and
extra fluid from your body and to return electrolyte levels to normal. Unlike
in-center hemodialysis, you do not need to travel to a dialysis
center for your treatment. Instead, after being trained at a dialysis center,
you will do your treatment at home on your own schedule. Peritoneal dialysis
can often be done at night, while you are sleeping.
You will need to have a
catheter placed in your belly (dialysis access) before you begin
dialysis. Placement is usually done 10 to 14 days before dialysis starts. Some
peritoneal dialysis catheters may be used immediately (acute-use catheters).
But because of a high risk of complications, these catheters are not commonly
The process of doing peritoneal dialysis is called an

There are different types of peritoneal dialysis. Discuss these

Peritoneal dialysis replaces the work
of the kidneys after complications of
kidney failure develop.
Peritoneal dialysis provides
approximately 10% of normal kidney function. It does not reverse chronic kidney
disease or kidney failure.
The most common complications from peritoneal
dialysis include infection around the catheter site or infection of the lining
of the abdominal wall (peritonitis).
Less commonly, there may be problems related to the catheter. But most
complications can be managed or prevented.
Peritoneal dialysis is
not recommended when any of the following conditions are present:
Peritoneal dialysis is a good
treatment option for people who have kidney failure. Advantages include:
