Resources - Kidney Dialysis
What do my kidneys do?
Your kidneys clean waste and extra fluid from your blood. This makes up your urine (pee). They also do many other jobs that you need in order to live. Your kidneys:
- Control chemicals and fluid in your body
- Help control your blood pressure
- Help keep your bones healthy
- Help you make red blood cells
Where are my kidneys?
Your kidneys are part of your urinary tract. They are located on either side of your spine, just below your rib cage. Each kidney is connected to your bladder by a thin tube called a ureter.
What is kidney disease?
The term "chronic kidney disease" (CKD) means lasting damage to the kidneys that can get worse over time. If the damage is very bad, your kidneys may stop working. This is called kidney failure. If your kidneys fail, you will need dialysis or a kidney transplant in order to live.
CKD can be caused by many different diseases. The most common causes of CKD are diabetes and high blood pressure. Some infections, inherited diseases and injuries can also cause CKD.
Treating Kidney Disease
Treating kidney disease in its earlier stages can help slow it down and prevent related problems like anemia, bone disease and heart disease. But even with the best care, some people will develop kidney failure. This is when your kidneys are not working well enough to keep you alive on their own. When your kidneys fail, you need dialysis or a kidney transplant in order to live.
There are a few different treatment options that you will need to consider. Work with your healthcare team to find the option that works best for you.
Dialysis is a treatment for kidney failure. It helps replace the work of the kidneys when they have stopped working. Hemodialysis is a type of dialysis.
What is hemodialysis?
Hemodialysis is a way of cleaning wastes and extra fluids from your blood using a machine.
In hemodialysis, blood goes through a tube from your body to a special filter called a dialyzer. The dialyzer filters waste and extra fluid from your blood. Then, the "clean" blood travels through another tube and back into your body.
Where can I get hemodialysis treatments?
In most cases, hemodialysis is done at a dialysis center. This is sometimes called "in-center hemodialysis." Your doctor will decide how often you need treatment, but most people have in-center hemodialysis treatments three times per week. Each treatment usually lasts about three to five hours.
Some things to consider about in-center hemodialysis are:
- You may need help getting to and from the dialysis center.
- Some centers have more flexible hours than others.
- Your doctor may only work with a few dialysis centers in your area.
- During your hemodialysis treatments, you can do several activities. Many people use their time at the dialysis center to:
- Read a book
- Listen to music
- Play hand-held video games
- Do crossword puzzles
- Take a nap
In some cases, hemodialysis can be done at home. This means that you (and usually a partner) would need to be trained on how to insert needles and run the machine. Many dialysis centers have staff that can train you to do home hemodialysis.
What is an access?
For hemodialysis, blood is taken from your body, cleaned and returned to your body. This happens through a place on your body called an access (or vascular access). There are three types of access:
A fistula (also called an AV fistula) is a place where one of your arteries connects to one of your veins. Your fistula would be created during a minor surgery and would need time to heal and "mature" before it can be used. Then, during dialysis treatments, needles will be put into your matured fistula.
In most cases, your fistula will be placed in your non-dominant arm. This means that if you are right-handed, your fistula would likely be in your left arm.
A fistula is the best kind of access. It is the least likely to get clots or infections. Fistulas also tend to last longer than other types of access. But, because fistulas can take longer to heal, it is important to plan ahead. Talk to your doctor about your options and whether a fistula is right for you.
A graft (also called an AV graft) is a special tube that connects an artery and a vein in your arm. Like with a fistula, a graft would be placed under your skin during a minor surgery. Your graft will need time to heal, too, but it probably won't take as long as a fistula to be ready. During dialysis treatments, needles will be put into the graft.
In most cases, your graft will be placed in your non-dominant arm. This means that if you are right handed, your graft would likely be in your left arm.
Grafts are not as safe as fistulas. They are a little more likely to have infections or get clots. Still, many people do well with grafts. Talk to your doctor about your options and whether a graft is right for you.
A catheter is a tube that goes directly into a vein in your neck or leg. During dialysis treatments, the machine takes blood from your catheter and returns blood to your catheter. This means that you won't have needle sticks at each treatment, like you would have with a fistula or a graft. But catheters are more likely to get infected or have clots. For this reason, catheters are only recommended in emergencies or for short-term use.
How should I care for my access?
Caring for your access is very important! Your access lets you have the treatment you need in order to live. Take good care of your access, no matter which kind you have.
To care for fistulas and grafts:
- Keep the area clean
- Use your access only for dialysis
- Do not have blood tests or check blood pressure on your access arm
- Avoid having tight clothing or jewelry near your access
- Protect your access from bumps and cuts
- Avoid lifting heavy objects
- Try not to lay or sleep on your access
- Learn how your needles will be placed for dialysis (The staff at your dialysis center can help you with this.)
- Make sure that the staff at your dialysis center checks your access at each treatment
- Tell your doctor right away if you notice any swelling, redness or other changes in your access
To care for a catheter:
- Make sure that all clamps are closed and caps are on tight
- Protect the area from water and dirt as much as possible
- Keep the area clean, dry and bandaged
- Clean and re-bandage the area at each treatment (The staff at your dialysis center can help, but make sure that you know how to do this at home in case the bandage becomes wet or dirty between treatments.)
- Tell your doctor right away if you have a fever or notice any swelling, redness or other changes around the access
Peritoneal Dialysis (PD)
Dialysis is a treatment for kidney failure. It helps replace the work of the kidneys when they have stopped working. Peritoneal dialysis (also called PD) is a type of dialysis.
What is PD?
PD is a way of cleaning waste and extra fluid from your blood. PD uses a special fluid called dialysate and the lining of your belly to do this.
The organs in your belly are inside a special lining called the peritoneum. This natural lining is thin and acts like a filter. It lets some things through and keeps others out.
For PD, you will have a soft flexible tube (called a catheter) that goes from outside your body to inside your peritoneum. This catheter is placed during a minor surgery. Then, you will:
- Put dialysate fluid into your belly through your catheter
- Let the dialysate sit in your belly for several hours
- During this time, the dialysate fluid pulls waste and extra fluid out of your blood. This is called the "dwell time."
- Drain the dialysate, along with the waste and extra fluid, out through your catheter
- Put new dialysate fluid into your belly and repeat the process
This process is called an exchange. Your doctor will tell you how many exchanges to do each day. Your doctor will also tell you what kind of dialysate to use.
Where can I do PD treatments?
PD treatments are usually done at home in a clean, dry place. Because PD is fairly portable, you may also do it while traveling. This makes it a more flexible treatment option.
While you do not need to go to a dialysis center for your treatments, you will still need to work with a center to learn how to do your PD exchanges and to get your supplies.
How can I stay healthy on PD?
One of the most common problems with PD is the risk of peritonitis. This is when your peritoneum, that natural lining in your belly, gets infected. This might happen if germs get into your belly through your catheter.
Bad infections can keep you from being able to do the PD treatments you need. To help prevent an infection:
- Learn the right way to do your exchanges
- The staff at your dialysis center can help. Don't be afraid to ask questions.
- Keep all of your PD supplies in a clean, dry place
- Do all of your exchanges in a clean, dry place
- Always wash your hands before doing an exchange
- Wear a surgical mask when you do exchanges
If you think you do have an infection, get treatment quickly. Tell your doctor right away if:
- You see pink or red around your catheter
- You have pain around your catheter
- Your catheter shifts or starts to come out
- Any of the clamps on your catheter break
- Your dialysate looks cloudy
- You have a fever
- You feel very sick or throw up
How long can a person live on dialysis?
There is no limit to how long a person can live on dialysis. On average, the life expectancy for someone on dialysis is between five and six years, but this can vary a lot depending on a person's age, other health concerns and how well he/she follows his/her treatment plan. With good care, it is very possible for a person to live for many years on dialysis.
What should I do if I have a complaint about my dialysis center?
Any problems that you have with your dialysis center should be taken up the chain of command. If you can't work out the problem with the person directly involved, talk with the Charge Nurse. If the problem continues, talk with the Director of Nursing, then the Administrator. Also let your doctor know about any problems you are having. If you are still having trouble with your dialysis center, contact the ESRD Network for your area or your state health inspector.
A dialysis diet controls the amount of potassium, phosphorus, sodium and liquid in your diet. The dialysis diet also provides you with enough calories and protein to be healthy. Your caregiver will help you plan a diet with the right amount of phosphorus, potassium, sodium, fluid, and other nutrients for you. If you need peritoneal (per-I-toh-NEE-al) dialysis, your diet may not be as limited as a person who needs hemodialysis (he-mo-deye-AL-I-sis). Your diet may need to change over time based on your weight, blood test results, and other reasons.
You may also need to make other diet changes if you have other health problems. These health problems may include diabetes, heart disease, high blood pressure and other health conditions.
What can I do to make a dialysis diet part of my lifestyle?
Changing what you eat and drink may be hard at first. Following a dialysis diet may help you feel better. Think of these changes as "lifestyle" changes, not just "diet" changes. You will need to make these changes part of your daily routine.
- Choose a variety of foods on this diet to avoid getting tired of having the same foods every day. Keep a list of items allowed on this diet in your kitchen to remind you about the diet.
- Carry a list of items allowed on this diet to remind you about the diet when you are away from home. Tell your family or friends about this diet so that they can help you follow the diet.
- Ask your caregiver, a dietitian, or a nutritionist any questions you may have about your diet plan. A dietitian or nutritionist works with you to find the right diet plan for you.

What other diet guidelines should I follow?
- Any food that contains liquid, such as soup, must be added in the amount of liquid that you may have each day. Any food that melts when it is not cold, such as gelatin or ice cream, must also be counted.
- Ask your caregiver if you should make other diet changes because of other health problems you may have. You may need to take a vitamin and mineral supplement (pill). Your caregiver will recommend the right vitamin and mineral supplement for you if you need one.
- You may need to stop using salt substitutes because they also contain potassium.
- Eat high fiber foods to avoid becoming constipated. Constipation is having dry, hard stools that are difficult to pass. High fiber foods include vegetables and fruits, whole grains (whole wheat bread and bran cereals) and legumes (beans, lentils). Eat only the amounts of high fiber foods suggested by your caregiver to avoid getting too much potassium, phosphorus and sodium.
- Following a dialysis diet may cause you to lose interest in eating. This may happen because foods may taste different than they used to. It may also happen because you will not be able to eat certain favorite foods. If you do not eat enough food, your body may not get the calories, protein, and other nutrients you need to be healthy. Talk to your caregiver if you lose interest in eating.
- Not following a dialysis diet may cause malnutrition (your body does not get the right amount of nutrients to work properly). You may have trouble controlling your blood pressure and balancing blood chemicals and fluids. You may also develop other health problems.
- Some over-the-counter vitamin and mineral supplements can be harmful if you are on dialysis. Take only the vitamin and mineral supplements suggested or ordered by your doctor.
You have the right to help plan your care. To help with this plan, you must learn about your diet. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
