KIDNEY FAILURE: CHOOSING A TREATMENT THAT'S RIGHT FOR YOU
On this page:
Introduction Your kidneys filter wastes from your blood and regulate other functions of your body. When your kidneys fail, you need treatment to replace the work your kidneys normally perform. Developing kidney failure means that you have some decisions to make about your treatment. If you choose to receive treatment, your choices are hemodialysis, peritoneal dialysis, and kidney transplantation. Each of them has advantages and disadvantages. You may also choose to forgo treatment. By learning about your choices, you can work with your doctor to decide what's best for you. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of your health care team, family, and friends, you can lead a full, active life [Top] When Your Kidneys Fail Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, harmful wastes build up in your body, your blood pressure may rise, and your body may retain excess fluid and not make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys. [Top] Treatment Choice: Hemodialysis Purpose Hemodialysis cleans and filters your blood using a machine to temporarily rid your body of harmful wastes, extra salt, and extra water. Hemodialysis helps control blood pressure and helps your body keep the proper balance of important chemicals such as potassium, sodium, calcium, and bicarbonate. How It Works Hemodialysis uses a special filter called a dialyzer that functions as an artificial kidney to clean your blood. During treatment, your blood travels through tubes into the dialyzer, which filters out wastes and extra water. Then the cleaned blood flows through another set of tubes back into your body. The dialyzer is connected to a machine that monitors blood flow and removes wastes from the blood.  Hemodialysis. Hemodialysis is usually needed three times a week. Each treatment lasts from 3 to 5 or more hours. During treatment, you can read, write, sleep, talk, or watch TV. Getting Ready If you choose hemodialysis, several months before your first treatment, an access to your bloodstream will need to be created. You may need to stay overnight in the hospital, but many patients have their access placed on an outpatient basis. This access provides an efficient way for blood to be carried from your body to the dialyzer and back without causing discomfort. The two main types of access are a fistula and a graft.
 Arteriovenous fistula. Before dialysis, needles are placed into the access to draw out the blood. You'll be given a local anesthetic to minimize any pain  Graft. If your kidney disease has progressed quickly, you may not have time to get a permanent vascular access before you start hemodialysis treatments. You may need to use a catheter, a tube inserted into a vein in your neck, chest, or leg near the groin, as a temporary access. Some people use a catheter for long-term access as well. Catheters that will be needed for more than about 3 weeks are designed to be placed under the skin to increase comfort and reduce complications.  Catheter for temporary access. For more information about vascular access, see the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) fact sheet Vascular Access for Hemodialysis. Who Performs It Hemodialysis is usually done in a dialysis center by nurses and trained technicians. In some parts of the country, it can be done at home with the help of a partner, usually a family member or friend. If you decide to do home dialysis, you and your partner will receive special training. Possible Complications Vascular access problems are the most common reason for hospitalization among people on hemodialysis. Common problems include infection, blockage from clotting, and poor blood flow. These problems can keep your treatments from working. You may need to undergo repeated surgeries in order to get a properly functioning access. Other problems can be caused by rapid changes in your body's water and chemical balance during treatment. Muscle cramps and hypotension–a sudden drop in blood pressure–are two common side effects. Hypotension can make you feel weak, dizzy, or sick to your stomach. You'll probably need a few months to adjust to hemodialysis. Side effects can often be treated quickly and easily, so you should always report them to your doctor and dialysis staff. You can avoid many side effects if you follow a proper diet, limit your liquid intake, and take your medicines as directed. Diet for Hemodialysis Hemodialysis and a proper diet help reduce the wastes that build up in your blood. A dietitian is available at all dialysis centers to help you plan meals according to your doctor's orders. When choosing foods, remember to

[Top] Treatment Choice: Peritoneal Dialysis Purpose Peritoneal dialysis is another procedure that removes extra water, wastes, and chemicals from your body. This type of dialysis uses the lining of your abdomen to filter your blood. This lining is called the peritoneal membrane and acts as the artificial kidney. How It Works A mixture of minerals and sugar dissolved in water, called dialysis solution, travels through a soft tube into your abdomen. The sugar, called dextrose, draws wastes, chemicals, and extra water from the tiny blood vessels in your peritoneal membrane into the dialysis solution. After several hours, the used solution is drained from your abdomen through the tube, taking the wastes from your blood with it. Then you fill your abdomen with fresh dialysis solution, and the cycle is repeated. The process of draining and refilling is called an exchange.  Peritoneal Dialysis. Getting Ready Before your first treatment, a surgeon places a small, soft tube called a catheter into your abdomen. The catheter tends to work better if there is adequate time–usually from 10 days to 2 or 3 weeks–for the insertion site to heal. Planning your dialysis access can improve treatment success. This catheter stays there permanently to help transport the dialysis solution to and from your abdomen. Types of Peritoneal Dialysis Three types of peritoneal dialysis are available. CAPD requires no machine and can be done in any clean, well-lit place. With CAPD, your blood is always being cleaned. The dialysis solution passes from a plastic bag through the catheter and into your abdomen, where it stays for several hours with the catheter sealed. The time period that dialysis solution is in your abdomen is called the dwell time. Next, you drain the dialysis solution into an empty bag for disposal. You then refill your abdomen with fresh dialysis solution so the cleaning process can begin again. With CAPD, the dialysis solution stays in your abdomen for a dwell time of 4 to 6 hours (or more). The process of draining the used dialysis solution and replacing it with fresh solution takes about 30 to 40 minutes. Most people change the dialysis solution at least four times a day and sleep with solution in their abdomen at night. With CAPD, it's not necessary to wake up and perform dialysis tasks during the night. CCPD uses a machine called a cycler to fill and empty your abdomen three to five times during the night while you sleep. In the morning, you begin one exchange with a dwell time that lasts the entire day. You may do an additional exchange in the middle of the afternoon without the cycler to increase the amount of waste removed and to reduce the amount of fluid left behind in your body. If you weigh more than 175 pounds or if your peritoneum filters wastes slowly, you may need a combination of CAPD and CCPD to get the right dialysis dose. For example, some people use a cycler at night but also perform one exchange during the day. Others do four exchanges during the day and use a minicycler to perform one or more exchanges during the night. You'll work with your health care team to determine the best schedule for you. Who Performs It Both types of peritoneal dialysis are usually performed by the patient without help from a partner. CAPD is a form of self-treatment that needs no machine. However, with CCPD, you need a machine to drain and refill your abdomen. Possible Complications The most common problem with peritoneal dialysis is peritonitis, a serious abdominal infection. This infection can occur if the opening where the catheter enters your body becomes infected or if contamination occurs as the catheter is connected or disconnected from the bags. Peritonitis requires antibiotic treatment by your doctor. To avoid peritonitis, you must be careful to follow procedures exactly and learn to recognize the early signs of peritonitis, which include fever, unusual color or cloudiness of the used fluid, and redness or pain around the catheter. Report these signs to your doctor immediately so that peritonitis can be treated quickly to avoid serious problems. Diet for Peritoneal Dialysis A peritoneal dialysis diet is slightly different from a hemodialysis diet.

Dialysis Is Not a Cure Hemodialysis and peritoneal dialysis are treatments that help replace the work your kidneys did. These treatments help you feel better and live longer, but they don't cure kidney failure. Although patients with kidney failure are now living longer than ever, over the years kidney disease can cause problems such as heart disease, bone disease, arthritis, nerve damage, infertility, and malnutrition. These problems won't go away with dialysis, but doctors now have new and better ways to prevent or treat them. You should discuss these complications and treatments with your doctor. [Top] Treatment Choice: Kidney Transplantation Purpose Kidney transplantation surgically places a healthy kidney from another person into your body. The donated kidney does the work that your two failed kidneys used to do. How It Works A surgeon places the new kidney inside your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Your blood flows through the donated kidney, which makes urine, just like your own kidneys did when they were healthy. The new kidney may start working right away or may take up to a few weeks to make urine. Unless your own kidneys are causing infection or high blood pressure, they are left in place.  Kidney transplantation. Getting Ready The transplantation process has many steps. First, talk with your doctor, because transplantation isn't for everyone. Your doctor may tell you that you have a condition that would make transplantation dangerous or unlikely to succeed. You may receive a kidney from a member of your family (living, related donor), from a person who has recently died (deceased donor), or sometimes from a spouse or a friend (living, unrelated donor). If you don't have a living donor, you're placed on a waiting list for a deceased donor kidney. The wait for a deceased donor kidney can be several years. The transplant team considers three factors in matching kidneys with potential recipients. These factors help predict whether your body's immune system will accept the new kidney or reject it.
How long you'll have to wait for a kidney varies. Because there aren't enough deceased donors for every person who needs a transplant, you must be placed on a waiting list. However, if a voluntary donor gives you a kidney, the transplant can be scheduled as soon as you're both ready. Avoiding the long wait is a major advantage of living donation. The surgery takes 3 to 4 hours. The usual hospital stay is about a week. After you leave the hospital, you'll have regular follow-up visits. If someone has given you a kidney, the donor will probably stay in the hospital about the same amount of time. However, a new technique for removing a kidney for donation uses a smaller incision and may make it possible for the donor to leave the hospital in 2 to 3 days. Between 85 and 90 percent of transplants from deceased donors are working 1 year after surgery. Transplants from living relatives often work better than transplants from deceased donors because they're usually a closer match. Possible Complications Transplantation is the closest thing to a cure. But no matter how good the match, your body may reject your new kidney. A common cause of rejection is not taking medication as prescribed. Your doctor will give you drugs called immunosuppressants to help prevent your body's immune system from attacking the kidney, a process called rejection. You'll need to take immunosuppressants every day for as long as the transplanted kidney is functioning. Sometimes, however, even these drugs can't stop your body from rejecting the new kidney. If this happens, you'll go back to some form of dialysis and possibly wait for another transplant. Immunosuppressants can weaken your immune system, which can lead to infections. Some drugs may also change your appearance. Your face may get fuller; you may gain weight or develop acne or facial hair. Not all patients have these problems, though, and diet and makeup can help. Immunosuppressants work by diminishing the ability of immune cells to function. In some patients, over long periods of time, this diminished immunity can increase the risk of developing cancer. Some immunosuppressants can cause cataracts, diabetes, extra stomach acid, high blood pressure, and bone disease. When used over time, these drugs may also cause liver or kidney damage in a few patients. Diet for Transplantation Diet for transplant patients is less limited than it is for dialysis patients, although you may still have to cut back on some foods. Your diet will probably change as your medicines, blood values, weight, and blood pressure change.

[Top] Treatment Choice: Refusing or Withdrawing From Treatment For many people, dialysis and transplantation not only extend life but also improve quality of life. For others who have serious ailments in addition to kidney failure, dialysis may seem a burden that only prolongs suffering. You have the right to refuse or withdraw from dialysis if you feel you have no hope of leading a life with dignity and meaning. You may want to speak with your spouse, family, religious counselor, or social worker as you make this decision. If you withdraw from dialysis treatments or refuse to begin them, you may live for a few days or for several weeks, depending on your health and your remaining kidney function. Your doctor can give you medicines to make you more comfortable during this time. Should you change your mind about refusing dialysis, you may start or resume your treatments at any time. Even if you're satisfied with your quality of life on dialysis, you should think about circumstances that might make you want to stop dialysis treatments. At some point in a medical crisis, you might lose the ability to express your wishes to your doctor. An advance directive is a statement or document in which you give instructions either to withhold treatment or to provide it, depending on your wishes and the specific circumstances. An advance directive may be a living will, a document that details the conditions under which you would want to refuse treatment. You may state that you want your health care team to use all available means to sustain your life. Or you may direct that you be withdrawn from dialysis if you become permanently unresponsive or fall into a coma from which you won't awake. In addition to dialysis, other life-sustaining treatments that you may choose or refuse include
Another form of advance directive is called a durable power of attorney for health care decisions or a health care proxy. In this type of advance directive, you assign a person to make health care decisions for you if you become unable to make them for yourself. Make sure the person you name understands your values and is willing to follow through on your instructions. Each State has its own laws governing advance directives. You can obtain a form for an advance medical directive that's valid in your State from the National Hospice and Palliative Care Organization (see the Resources section). [Top] Paying for Treatment Treatment for kidney failure is expensive, but Federal health insurance plans pay much of the cost, usually up to 80 percent. Often, private insurance or State programs pay the rest. For more information, see the NIDDK fact sheet Financial Help for Treatment of Kidney Failure. [Top] Conclusion Deciding which type of treatment is best for you isn't easy. Your decision depends on your medical condition, lifestyle, and personal likes and dislikes. Discuss the pros and cons of each treatment with your health care team and family. You can switch between treatment methods during the course of your therapy. If you start one form of treatment and decide you'd like to try another, talk with your doctor. The key is to learn as much as you can about your choices first. With that knowledge, you and your doctor will choose the treatment that suits you best.
