Home hemodialysis is also an option for some patients. Peritoneal dialysis is another type of dialysis that removes waste products from the blood when your kidneys are not functioning properly. The biggest difference in hemodialysis vs peritoneal dialysis is that hemodialysis requires an artificial kidney machine to filter blood while peritoneal dialysis does not. Rather than using a machine, peritoneal dialysis uses the lining on the inside of the belly as a natural filter for blood.
During peritoneal dialysis, the dialysate flows through a catheter into part of the abdomen. The peritoneum, which is the lining of your abdomen, acts as a natural filter and removes the waste products from your blood.
However, this type of dialysis is not ideal for all patients. There are two types of peritoneal dialysis: continuous ambulatory peritoneal dialysis CAPD and automated peritoneal dialysis. With continuous ambulatory peritoneal dialysis CAPD , the abdomen is filled with dialysate. The patient lets it stay in the abdomen for a prescribed dwell time before draining the fluid.
Gravity moves the fluid through the catheter without machine assistance. Exchanges can be done pretty much anywhere that is clean and sanitized. Patients can continue their activities while the dialysate dwells in the abdomen.
Automated peritoneal dialysis is also known as continuous cycling peritoneal dialysis CCPD. This type of dialysis uses a machine that cycles through multiple exchanges at night while you sleep. The machine fills your abdomen with dialysate and allows it to dwell there for a while before draining into a sterile bag.

Hemodialysis vs. November 21, pm. If your kidneys are unable to function on their own, you will need dialysis to help flush toxins from your blood to keep your body healthy. Dialysis replaces the function of your kidneys by removing waste and excess fluid from your bloodstream.
Dialysis can be conducted at home or at a treatment center. Although both types of dialysis can effectively filter your blood, the benefits of peritoneal dialysis compared with hemodialysis include:. Talk with your doctor about which type of dialysis might be best for you. Factors to consider include:. It's also likely that people using peritoneal dialysis will eventually have a decline in kidney function that requires hemodialysis or a kidney transplant.
You'll need an operation to insert the catheter that carries the dialysate in and out of your abdomen. The insertion might be done under local or general anesthesia. The tube is usually inserted near your bellybutton. After the tube is inserted, your doctor will probably recommend waiting up to a month before starting peritoneal dialysis treatments to give the catheter site time to heal.
The process of filling and then draining your abdomen is called an exchange. Different methods of peritoneal dialysis have different schedules of exchange. The two main schedules are:. You fill your abdomen with dialysate, let it remain there for a prescribed dwell time, then drain the fluid.
Gravity moves the fluid through the catheter and into and out of your abdomen. Also known as automated peritoneal dialysis APD , this method uses a machine automated cycler that performs multiple exchanges at night while you sleep.
The cycler automatically fills your abdomen with dialysate, allows it to dwell there and then drains it to a sterile bag that you empty in the morning. To determine the method of exchange that's best for you, your doctor will consider your medical condition, lifestyle and personal preferences. Your doctor might suggest certain modifications to individualize your program.
Many factors affect how well peritoneal dialysis works in removing wastes and extra fluid from your blood. These factors include:.
To check if your dialysis is removing enough waste products, your doctor is likely to recommend tests, such as:. If the test results show that your dialysis schedule is not removing enough wastes, your doctor might change your dialysis routine to:. You can improve your dialysis results and your overall health by eating the right foods, including foods low in sodium and phosphorus.
