Kidney Transplant: What It Means and What to Ask

A kidney transplant is surgery that places a healthy kidney from another person into your body. The surgeon puts the new kidney in your lower belly and connects it to your blood vessels and bladder. Your own kidneys usually stay where they are unless there is a medical reason to remove them. Once it starts working, the new kidney filters your blood and removes waste and extra fluid in urine.

A transplant can free you from dialysis, but it is a treatment, not a cure. The condition that damaged your kidneys can sometimes come back in the new kidney, and you will need anti-rejection medicines and regular checkups for as long as the transplant works.

Two kinds of donors

• Living donor. A relative, spouse or partner, friend, or even someone anonymous donates one of their kidneys. Surgery can be scheduled, and some people receive a kidney before ever starting dialysis. These kidneys often work for longer.

• Deceased donor. The kidney comes from a person who died and chose to donate. You join a national waiting list, and how long you wait depends on your blood type, tissue match, body size, and where you live. Waits range from months to several years.

Most transplants work well for many years, and many people say the surgery changed their life. If a transplant slows down or fails over time, you can go back on dialysis and, in many cases, be evaluated for another transplant.

The first step is a conversation. Ask your kidney doctor for a referral to a transplant center. The evaluation tells you whether a transplant is an option for you and what your personal risks are.

The evaluation usually takes one or more visits: blood and urine tests including blood and tissue type, heart checks such as an ECG or echocardiogram, and reviews of cancer screenings, dental health, and lung function. You will meet a transplant surgeon or doctor, a nurse coordinator, a dietitian, and a social worker, who also talk with you about costs, insurance, and the help you will need at home during recovery.

If the center accepts you, they place you on the national waiting list for a deceased-donor kidney, and you keep dialyzing while you wait. A match can call at any hour, so keep your phone reachable and plan how you would travel to the hospital in the middle of the night.

A living donor is another path. If you are comfortable doing so, let family and friends know you are interested. The center screens anyone who offers separately, and a donor's kindness never obligates you. Your own testing continues while you are listed so you stay ready for surgery.

Questions worth asking your team

• What are my personal risks with surgery and with anti-rejection medicines?

• How long do people with my blood type usually wait at this center?

• What costs does my insurance cover, and what help is available?

• Who do I call when I have a question between visits?

When a deceased-donor kidney matches you, the transplant team calls you in and asks you to stop eating and drinking until surgery. Expect the call at any time; many transplants happen at night. At the hospital, the team repeats some tests to make sure you are still healthy for surgery: a chest X-ray, blood tests, and a brief exam. If you have a fever or an infection, the surgery may be postponed. That feels crushing after a long wait, but it protects you.

The surgery takes three to five hours under general anesthesia. The surgeon places the new kidney in your lower belly, connects it to your blood vessels and your bladder, and usually leaves your own kidneys in place. A small tube called a catheter drains urine from your bladder for a few days while things settle.

Most people stay in the hospital for about three to seven days. Anti-rejection medicines start right away, and by the time you leave you should know your medicine schedule and follow-up appointments.

Expect your body to need time. The incision is sore for a few weeks, walking short distances helps you recover faster than staying in bed, and many people feel tired at first while their energy returns gradually. Some swelling is common early on; your team tracks your weight at every visit.

Blood tests are frequent at first, sometimes daily in the hospital and then weekly, so the team can watch how the new kidney works and adjust your medicine doses. Visits become less frequent as things stabilize. Keep every appointment even when you feel well, because the tests catch problems before symptoms do.

Take your medicines at set times, some with food and some without. A weekly pill box and phone alarms help. Missing anti-rejection doses is the most preventable cause of rejection, so tell your team right away if you vomit a dose, oversleep through one, or have trouble paying for a refill.

While your immune system is suppressed, infections are easier to catch. In the early months, many teams advise avoiding crowds and people who are sick, washing your hands often, and following food safety rules, such as cooking meat and eggs thoroughly. Your team will tell you when the rules relax.

Emotions run wide during recovery. Gratitude, anxiety about rejection, and mood changes from the medicines are all common, and the social worker at your center can connect you with support groups.

After a transplant, your immune system is deliberately slowed down, so infections can become serious quickly and rejection often starts without obvious symptoms. Watch your body closely, and call when something feels wrong.

Rejection often shows up in blood tests before you feel anything, which is why the frequent labs matter so much. If a result suggests rejection, the team may arrange a biopsy and adjust your medicines. Never change doses on your own.

Call the same day for

• A new rash, mouth sores, or shingles-like blisters

• Diarrhea or vomiting lasting more than a day

• Signs of dehydration, such as dizziness when standing

• Any symptom you are unsure about; the team would rather hear from you

What can usually wait for your next visit

• Small weight changes between appointments

• Mild constipation

• Questions about how your incision is healing

If you are ever unsure which list your symptom belongs on, call. Transplant teams expect these calls, and acting early protects the kidney you waited for.

Anti-rejection medicines, sometimes called immunosuppressants, are part of your life for as long as the transplant works. Common ones include tacrolimus, cyclosporine, mycophenolate, and prednisone. They keep your immune system from attacking the new kidney. You will take them every day even on good days, and running out is an emergency, not an inconvenience. Order refills early, keep a few days of medicine with you when you travel, and carry them in your hand luggage, not a checked bag.

Some everyday things interfere with these medicines. Grapefruit and grapefruit juice can change how tacrolimus and cyclosporine work, and herbal products can too, including St. John's wort. Before starting any new medicine, supplement, or vaccine, check with your transplant team, and tell every doctor, dentist, and pharmacist that you have a transplant.

Your long-term health now includes watching blood pressure, blood sugar, and cholesterol, because the medicines can raise them. Skin protection matters too: immunosuppression raises skin cancer risk, so use sunscreen and ask about regular skin checks. Many vaccines are recommended after a transplant, but some live vaccines are not given, so always ask your team first.

Life opens up again for most people. Many return to work, drive, travel, and enjoy food they avoided on dialysis. Some go on to have children, and pregnancy is possible with careful planning with your team. Keep asking questions; people who understand their medicines and show up for appointments give their kidney the best chance.
