Dialysis is a treatment for kidney failure that helps filter
waste products from the blood when the kidneys are not working properly. The
two main types of dialysis are hemodialysis and peritoneal dialysis.
Hemodialysis uses a man-made membrane
(dialyzer) to filter wastes and remove extra fluid from the blood. It is
usually done in a hospital or outpatient dialysis center 3 times a week.
Some types of hemodialysis
are done at home.
Peritoneal dialysis uses the lining of the abdomen
(peritoneal membrane) and a solution (dialysate) to remove wastes and
extra fluid from the body. Treatment can be done at home over several sessions
each day or for several hours at night.
