Kidney TransplantationWhat is a kidney transplant?
A kidney transplant is an operation done to replace a diseased kidney with a healthy one from another person. The kidney may come from an organ donor or from a live donor either related or not related, who is willing to donate the kidney and is a suitable candidate to donate.
Why is a kidney transplant recommended?
|A kidney transplant is recommended for children who have serious kidney dysfunction and will not be able to live without dialysis or a transplant. Some of the kidney diseases in children for which transplants are done include the following. However, not all cases of the following diseases require kidney transplantation. Always consult your child's physician for a diagnosis.|
Congenital renal obstructive disorders leading to hydronephrosis, including the following:
How many children in the United States need kidney transplants?
|According to the latest statistics from The United Network for Organ Sharing (UNOS), 643 children were waiting for a kidney transplant in the United States on November 30, 2000, including the following:|
Where do transplanted organs come from?
|The majority of kidneys that are transplanted come from deceased organ donors. Organ donors are adults or children who have become critically ill and will not live as a result of their illness. An adult donor may have agreed to be an organ donor before becoming ill. Parents or spouses can also agree to donate a relative's organs. Donors can come from any part of the United States. This type of transplant is called a cadaveric transplant. |
|A child receiving a transplant usually receives only one kidney, but, in rare situations, the child may receive two kidneys from a cadaveric donor. Family members or individuals who are unrelated but make a good match may also be able to donate one of their kidneys. This type of transplant is called a living transplant. Individuals who donate a kidney can live healthy lives with the kidney that remains. Most children requiring kidney transplants weigh more than 15 kilograms, or 33 pounds.|
How are transplanted organs allocated?
|The United Network for Organ Sharing (UNOS) is responsible for transplant organ distribution in the United States. UNOS oversees the allocation of many different types of transplants, including liver, kidney, pancreas, heart, lung and cornea. |
|UNOS receives data from hospitals and medical centers throughout the country regarding adults and children who need organ transplants. The medical transplant team that currently follows your child is responsible for sending the data to UNOS and updating them as your child's condition changes. |
|Criteria have been developed to ensure that all people on the waiting list are judged fairly as to the severity of their illness and the urgency of receiving a transplant. Once UNOS receives the data from local hospitals, people waiting for a transplant are placed on a waiting list and given a "status" code. The people in most urgent need of a transplant are placed highest on the status list, and are given first priority when a donor kidney becomes available. |
|When a donor organ becomes available, a computer searches all the people on the waiting list for a kidney and sets aside those who are not good matches for the available kidney. A new list is made from the remaining candidates. The person at the top of the specialized list is considered for the transplant. If that person is not a good candidate, for whatever reason, the next person is considered, and so forth. Some reasons that people lower on the list might be considered before a person at the top include the size of the donor organ and the geographic distance between the donor and the recipient.|
How is my child placed on the waiting list for a new kidney?
|An extensive evaluation must be completed before your child can be placed on the transplant list. Testing includes:|
|Tests are done to gather information that will help determine how urgent it is that your child is placed on the transplant list, as well as ensure the child receives a donor organ that is a good match. These tests include those to analyze the general health of the body, including the child's heart, lung and kidney function, the child's nutritional status, and the presence of infection. Blood tests will help improve the chances that the donor organ will not be rejected. These tests may include:|
|Other blood tests will help improve the chances that the donor organ will not be rejected. They may include:|
The diagnostic tests that are performed are extensive, but necessary to understand the complete medical status of your child. The following are some of the other tests that may be performed, although many of the tests are decided on an individual basis:
The transplant team will consider all information from interviews, your child's medical history, physical examination and diagnostic tests in determining whether your child can be a candidate for kidney transplantation.
|After the evaluation and your child has been accepted to have a kidney transplant, your child will be placed on the United Network for Organ Sharing (UNOS) list.|
The kidney transplant team:
|The group of specialists involved in the care of children who are undergoing a transplant procedure is often referred to as the "transplant team." Each individual works together to provide the best chance for a successful transplant. The kidney transplant team consists of:|
|Transplant surgeons - physicians who specialize in transplantation and who will be performing the surgery. The transplant surgeons coordinate all team members. They follow your child before the transplant and continue to follow your child after the transplant and after discharge from the hospital. |
Nephrologists - physicians who specialize in disorders of the kidneys. Nephrologists will help manage your child before and after the surgery.
Urologists - physicians who specialize in diagnosis and treatment of disorders of the genitourinary tract.
Transplant nurse coordinator - a nurse who organizes all aspects of care provided to your child before and after the transplant. The nurse coordinator will provide patient education and coordinate the diagnostic testing and follow-up care.
Social workers - professionals who will provide support to your family and help your family deal with many issues that may arise including lodging and transportation, finances, and legal issues. They can also help coordinate alternative means for school, so that your child does not get behind.
Dietitians - professionals who will help your child meet his/her nutritional needs before and after the transplant. They will work closely with you and your family.
Child psychologists - a psychologist who specializes in children will assist both the family and staff to cope with kidney disease and transplant.
Pastoral care - chaplains who provide spiritual care and support.
Other team members - several other team members will evaluate your child before transplantation and provide follow-up care, as needed. These include, but are not limited to, the following:
How long will it take to get a new kidney?
|There is no definite answer to this question. Sometimes, children wait only a few days or weeks before receiving a donor organ. If no living-related donor is available, it may take months or years on the waiting list before a suitable donor organ is available. During this time, your child will receive close follow-up with the physicians and the transplant team.|
How are we notified when a kidney is available?
|You will be notified by phone or pager that an organ is available. You will be told to come to the hospital immediately so your child can be prepared for the transplant.|
What is involved in kidney transplant surgery?
|Once an organ becomes available to your child, you and your child will be immediately called to the hospital. This call can occur at any time, so you should always be prepared to go to the hospital, if needed. Once at the hospital, the child will have some more final blood work and tests to confirm the match of the organ. |
|The child will then go to the operating room. The transplant surgery may require several hours, but will vary greatly depending on each individual case. During the surgery, a member of the transplant team will keep you informed on the progress of the transplant.|
Post-operative care for kidney transplant:
|After the surgery, your child will go to the intensive care unit (ICU) to be monitored closely. The length of time your child will spend in the ICU will vary based on your child's unique condition. After your child is stable, your child will be sent to the special unit in the hospital that cares for kidney transplant patients and will continue to be monitored closely. You will be educated on all aspects of caring for your child during this time. This will include information about medications, activity, follow-up, diet and any other specific instructions from your child's transplant team.|
What is rejection?
|Rejection is a normal reaction of the body to a foreign object. When a new kidney is placed in a person's body, the body sees the transplanted organ as a threat and tries to attack it. The immune system makes antibodies to try to kill the new organ, not realizing that the transplanted kidney is beneficial. To allow the organ to successfully live in a new body, medications must be given to trick the immune system into accepting the transplant and not thinking it is a foreign object.|
What are the symptoms of rejection?
|The following are the most common signs and symptoms of rejection. However, each child may experience symptoms differently. Symptoms may include:|
Your transplant team will instruct you on who to call immediately if any of these symptoms occur.
What is done to prevent rejection?
|Medications must be given for the rest of the child's life to fight rejection. Each child is unique and the transplant team has preferences for different medications. Some of the anti-rejection medications most commonly used include the following:|
New anti-rejection medications are continually being approved. Physicians tailor drug regimes to meet the needs of each individual child. The doses of these medications may change frequently as your child's response to them changes. Because anti-rejection medications affect the immune system, children who receive a transplant will be at higher risk for infections. A balance must be maintained between preventing rejection and making your child very susceptible to infection. Blood tests to measure the amount of medication in the body are done periodically to make sure your child does not get too much or too little of the medications. White blood cells are also an important indicator of how much medication your child needs.
What about infection?
|This risk of infection is especially great in the first few months because higher doses of anti-rejection medications are given during this time. Your child will most likely need to take medications to prevent other infections from occurring. Some of the infections your child will be especially susceptible to include fungus (yeast), herpes and respiratory viruses.|
Long-term outlook for a child after a kidney transplant:
|Living with a transplant is a life-long process. Medications must be given that trick the immune system so it will not attack the transplanted organ. Other medications must be given to prevent side effects of the anti-rejection medications, such as infection. Frequent visits to and contact with the transplant team are essential. Knowing the signs of organ rejection (and watching for them on a daily basis) is critical. When the child becomes old enough, he will need to learn about anti-rejection medications (what they do and the signs of rejection), so he can eventually care for himself independently. |
|Every child is unique and every transplant is different. Results continually improve as physicians and scientists learn more about how the body deals with transplanted organs and search for ways to improve transplantation. |
