Kidney Transplant

What is a kidney transplant?

A kidney transplant is a surgery done to replace a diseased or injured kidney with a healthy kidney from a donor. The kidney may come from a deceased organ donor or from a living donor. Family members or others who are a good match may be able to donate one of their kidneys. This type of transplant is called a living transplant. People who donate a kidney can live healthy lives with one healthy kidney.

A person getting a transplant most often gets just one kidney. In rare situations, they may get two kidneys from a deceased donor. The diseased kidneys are usually left in place. The transplanted kidney is placed in the lower belly on the front side of the body.

Why might I need a kidney transplant?

You may need a kidney transplant if you have end-stage renal disease (ESRD). This is a permanent condition of kidney failure. It often needs dialysis. This is a process used to remove wastes and other substances from the blood.

The kidneys:

  • Remove urea and liquid waste from the blood in the form of urine. Urea is made when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the blood to the kidneys.

  • Balance salts, electrolytes, such as potassium and sodium, and other substances in the blood

  • Make erythropoietin, a hormone that helps red blood cells form

  • Regulate blood pressure

  • Regulate fluid and acid-base balance in the body to keep it neutral. This is needed for normal function of many processes within the body.

Some conditions of the kidneys that may result in ESRD include:

  • Repeated urinary infections

  • Kidney failure caused by diabetes or high blood pressure

  • Polycystic kidney disease or other inherited disorders

  • Glomerulonephritis, which is inflammation of the kidneys' filtering units

  • Hemolytic uremic syndrome, a rare disorder that causes kidney failure

  • Lupus and other diseases of the immune system

  • Obstructions

Other conditions, such as congenital defects of the kidneys, may result in the need for a kidney transplant.

There may be other reasons for your healthcare provider to recommend a kidney transplant.

What are the risks for kidney transplant?

As with any surgery, complications can occur. Some complications may include:

  • Bleeding

  • Infection

  • Blockage of the blood vessels to the new kidney

  • Leakage of urine or blockage of urine in the ureter

  • Lack of function of the new kidney at first

The new kidney may be rejected. Rejection is a normal reaction of the body to a foreign object or tissue. When a new kidney is transplanted into a recipient's body, the immune system reacts to what it thinks is a threat and attacks the new organ. For a transplanted organ to survive, medicines must be taken to trick the immune system into accepting the transplant and not attacking it as a foreign object.

The medicines used to prevent or treat rejection have side effects. The exact side effects will depend on the specific medicines that are taken.

Not everyone is a candidate for a kidney transplant. You may not be eligible if you have:

  • Current or recurring infection that cannot be treated effectively

  • Cancer that has spread from its original location to elsewhere in the body

  • Severe heart or other health problems that make it unsafe to have surgery

  • Serious conditions other than kidney disease that would not get better after the transplant

  • Failure to follow the treatment plan

There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your transplant team before the procedure.

How do I get ready for a kidney transplant?

To get a kidney from an organ donor who has died (cadaver), you must be placed on a waiting list of the United Network for Organ Sharing (UNOS). Extensive testing must be done before you can be placed on the transplant list.

A transplant team carries out the evaluation process for a kidney. The team includes a transplant surgeon, a transplant nephrologist (healthcare provider specializing in the treatment of the kidneys), one or more transplant nurses, a social worker, and a psychiatrist or psychologist. Other team members may include a dietitian, a chaplain, your primary care provider, and an anesthesiologist or nurse anesthetist.

The evaluation includes:

  • Mental health evaluation. Psychological and social issues involved in an organ transplant, such as stress, financial issues, and support by family and significant others are assessed. These issues can greatly affect the outcome of a transplant. The same kind of evaluation is done for a living donor.

  • Blood tests. Blood tests are done to help find a good donor match, to check your priority on the donor list, and to help the chances that the donor organ will not be rejected.

  • Diagnostic tests. Diagnostic tests may be done to check your kidneys as well as your overall health status. These tests may include X-rays, CT scan, ultrasound, kidney biopsy, and dental exams. Women may get a Pap test, gynecology evaluation, and a mammogram.

The transplant team will weigh all the facts from interviews, your medical history, physical exam, and tests to determine your eligibility for a kidney transplant.

Once you have been accepted as a transplant candidate, you will be placed on the UNOS list. When a donor organ becomes available, you will be notified and told to come to the hospital right away.

If you are to get a kidney from a living family member (living-related transplant), the transplant may be done at a planned time. The donor must have a compatible blood type and be in good health. A mental health check will be done to be sure the donor is comfortable with the decision.

These steps will happen before the transplant:

  • Your transplant team will explain the procedure to you, and you can ask questions.

  • You will be asked to sign a consent form that gives your permission to do the surgery. Read the form carefully and ask questions if something is not clear.

  • If you have been on routine dialysis before the procedure, you will get dialysis before the procedure.

  • For a planned living transplant, you should fast for 8 hours before the operation, generally after midnight. In the case of a cadaver organ transplant, you should start to fast once you are told a kidney has become available.

  • You may get a sedative before the procedure to help you relax.

  • Based on your medical condition, your transplant team may ask for other specific preparations.

What happens during a kidney transplant?

A kidney transplant requires a stay in a hospital. Procedures may vary depending on your condition and your healthcare provider's practices.

Generally, a kidney transplant follows this process:

  1. You will remove your clothing and put on a hospital gown.

  2. An IV (intravenous) line will be started in your arm or hand. More catheters may be put in your neck and wrist to monitor the status of your heart and blood pressure, and to take blood samples. Other sites for catheters include under the collarbone area and the groin blood vessels.

  3. If there is too much hair at the surgical site, it may be shaved off.

  4. A urinary catheter will be inserted into your bladder.

  5. You will be positioned on the operating table, lying on your back.

  6. Kidney transplant surgery will be done while you are asleep under general anesthesia. A tube will be inserted through your mouth into your lungs. The tube will be attached to a ventilator that will breathe for you during the procedure.

  7. The anesthesiologist or nurse anesthetist will closely watch your heart rate, blood pressure, breathing, and blood oxygen level during the surgery.

  8. The skin over the surgical site will be cleansed with an antiseptic solution.

  9. The surgeon will make a long incision into the lower abdomen on one side. The surgeon will visually inspect the donor kidney before implanting it.

  10. The donor kidney will be placed into the belly. A left donor kidney will be implanted on your right side; a right donor kidney will be implanted on your left side. This allows the ureter to be accessed easily for connection to your bladder.

  11. The renal artery and vein of the donor kidney will be sewn to the external iliac artery and vein.

  12. After the artery and vein are attached, the blood flow through these vessels will be checked for bleeding at the suture lines.

  13. The donor ureter (the tube that drains urine from the kidney) will be connected to your bladder.

  14. The incision will be closed with stitches or surgical staples.

  15. A drain may be placed in the incision site to reduce swelling.

  16. A sterile bandage or dressing will be applied.

Talk with your healthcare provider about what you will go through during your kidney transplant.

What happens after a kidney transplant?

In the hospital

  • After the surgery, you will be taken to the recovery room. Once your blood pressure, pulse, and breathing are stable and you are alert, you may be taken to the intensive care unit (ICU) for close monitoring. In time, you will be moved out of the ICU to a regular nursing unit as you recover and you are closer to going home. Kidney transplant usually calls for several days in the hospital.

  • A kidney from a living donor may start to make urine right away. Urine production in a cadaver kidney may take longer. You may need to continue dialysis until urine output is normal.

  • You will have a catheter in your bladder to drain your urine. The amount of urine will be measured to check how the new kidney is working.

  • You will get IV fluids until you are able to eat and drink enough on your own.

  • Your team will closely watch how your antirejection medicines are working to make sure you are getting the best dose and the best combination of medicines.

  • Blood samples will be taken often to check the status of the new kidney, as well as other body functions, such as the liver, lungs, and blood system.

  • You will slowly move from liquids to more solid foods as tolerated. Your fluids may be limited until the new kidney is working fully.

  • Usually, by the day after the procedure, you may start moving around. You should get out of bed and move around several times a day.

  • Take a pain reliever for soreness as advised by your healthcare provider. Don't take aspirin or certain other pain medicines that may increase the chance of bleeding. Be sure to take only recommended medicines.

  • Nurses, pharmacists, dietitians, physical therapists, and other members of the transplant team will teach you how to take care of yourself once you are discharged from the hospital, including care for your incisions.

  • You will be ready to go home when your vital signs are stable, the new kidney is working, and you do not need the constant hospital care.

At home

  • Once you are home, it is important to keep the surgical area clean and dry. Your healthcare provider will give you specific bathing instructions. Generally, the incision should not be submerged in water until the skin heals, as this increases the risk for infection. The stitches or surgical staples will be removed during a follow-up office visit.

  • You should not drive until your healthcare provider tells you it’s OK. Plan to have someone drive you home from the hospital and to your follow-up appointments.

  • Avoid any activity or position that causes pressure to be placed on the new kidney. Other activity restrictions may apply.

  • Check your blood pressure and weight at home every day. Increases in these may mean your kidneys are not filtering fluid properly. You need to be seen by your transplant team promptly.

Tell your healthcare provider if you have:

  • Fever, which may be a sign of rejection or infection

  • Redness, swelling, or bleeding or other drainage from the incision site

  • Increase in pain around the incision site, which may be a sign of rejection or infection

Fever and tenderness over the kidney are some of the most common symptoms of rejection. A rise in your blood creatinine level (blood test to measure kidney function) or blood pressure may also suggest rejection. The symptoms of rejection may look like other medical conditions or problems. Talk with your transplant team about any concerns you have. Frequent visits to and contact with the transplant team are vital.

Stay away from places where you could be exposed to anyone who may be sick. This is because your immune system will be suppressed to protect you from rejecting the new kidney. This will be a lifelong precaution.

Your healthcare team may give you other instructions after the procedure, depending on your situation.

What is done to prevent rejection

To allow the transplanted kidney to survive in your body, you will be given medicines for the rest of your life to fight rejection. Each person may react differently to medicines.

New antirejection medicines are continually being developed and approved. Your healthcare team will tailor a medicine regimen to meet your needs.

Usually several antirejection medicines are given at first. The doses of these medicines may change often, depending on your response. Because antirejection medicines affect the immune system, you will be at higher risk for infections. A balance must be maintained between preventing rejection and making you very susceptible to infection.

Some of the infections you will be especially at risk for include oral yeast infection (thrush), herpes, and respiratory viruses. Stay away from crowds and anyone who has an infection for the first few months after your surgery.
