At a glance
- A kidney transplant places a healthy donor kidney into a person whose kidneys have failed.
- For suitable patients it offers better quality of life and survival than long-term dialysis.
- Kidneys can come from a living donor or a deceased donor.
- Lifelong anti-rejection medication and follow-up are needed.
What a kidney transplant is
A kidney transplant is an operation to place a healthy kidney, from a living or deceased donor, into a person whose own kidneys have failed. For many suitable people it is the best available treatment for kidney failure, offering better quality of life and freedom from the routine of dialysis. Because a single healthy kidney can do the work the body needs, only one new kidney is transplanted. The failed kidneys are usually left in place; they are removed only if there is a specific reason, such as infection, large cysts or uncontrolled blood pressure. The new kidney is normally placed low in the abdomen, where it can be connected to nearby blood vessels and the bladder.
Who a transplant is for
A transplant is considered for people with kidney failure (end-stage chronic kidney disease), either before starting dialysis or while on it. A thorough assessment checks that the heart, blood vessels and general health are suitable and that there is no active infection or cancer. The transplant team weighs the benefits against the risks of surgery and of the medicines that follow, since not everyone with kidney failure is a safe candidate. Age alone does not decide suitability; overall fitness matters more. Where a health problem can be treated or improved first, the team may work on that before listing someone for transplant.
Living and deceased donors
A living-donor kidney — often from a relative or, under strict ethical and legal safeguards, another compatible donor — generally lasts longer and can be planned. A deceased-donor kidney comes through the national waiting list. Living donation is possible because a healthy adult can live a full, normal life with a single kidney. A potential living donor undergoes their own careful medical and psychological assessment to confirm that giving a kidney is safe for them and that the decision is free and informed. In Singapore, organ donation and transplantation are regulated by law under a national framework, which sets out how deceased-donor organs are allocated and safeguards living donation against any form of trading or coercion. A living-donor transplant has some clear advantages: it can be arranged when the recipient is in the best possible health, it often avoids or shortens time on dialysis, and the kidney tends to work well from the outset. A deceased-donor transplant makes it possible for people who do not have a suitable living donor to be treated, and remains a vital option. Both routes rely on generous, informed donation and on the same commitment to lifelong care afterwards.
Getting on the path: assessment and matching
Suitable candidates are placed on the national transplant waiting list, and donor kidneys are matched by blood group and tissue typing to reduce the risk of rejection. The work-up also screens for infections, heart and vessel disease, and cancer, and includes counselling so that the person understands the commitment involved. Living donation avoids the wait but requires a willing, healthy, compatible donor who undergoes their own careful assessment. For deceased-donor transplants, demand greatly exceeds supply, so waiting can be long; people remain under nephrology care and continue dialysis while they wait. Discussing transplantation early, ideally before dialysis is needed, allows time for this assessment and can open the door to a pre-emptive transplant.
How the surgery is done
The operation is performed under general anaesthetic. The donor kidney is placed in the lower abdomen and its blood vessels are joined to vessels in the pelvis, and its ureter (the tube that drains urine) is connected to the bladder; the original kidneys are usually left in place. A hospital stay follows the surgery so that the team can watch the new kidney closely, manage fluids and pain, and start the anti-rejection medicines. A living-donor operation can be scheduled in advance, while a deceased-donor transplant happens at short notice when a matched kidney becomes available.
Recovery after the operation
The new kidney often starts working immediately, though sometimes it takes days or longer to wake up, and temporary dialysis may be needed in the meantime until it does. In hospital, urine output, blood tests and the medicine levels are monitored carefully, and the team teaches the recipient how and when to take each medicine, what side effects to watch for, and which symptoms should prompt a call. After discharge, recovery continues over several weeks, and follow-up visits are frequent at first — often several times a week — then gradually spaced out as things settle. These visits check kidney function, adjust the anti-rejection medicines and look for early signs of rejection or infection, so attending every appointment matters. Wound care, gentle return to activity and gradually resuming normal life are all discussed with the team, and most people can return to work and everyday activities as they regain strength.
Anti-rejection medicines: the crucial lifelong part
Transplant recipients must take immunosuppressant (anti-rejection) medicines every day for as long as the kidney works, to stop the body from recognising and rejecting it. This is the single most important part of living with a transplant. These medicines must never be stopped, reduced or skipped without specialist advice, as doing so can trigger rejection and the loss of the kidney. Because they dampen the immune system, they also raise the risk of infections and of some cancers, so regular monitoring, blood tests and sensible precautions are part of everyday life. The team may adjust the combination over time to balance protecting the kidney against these side effects; any changes come from the transplant team, never from stopping on one’s own.
Signs of rejection and other complications
Rejection is the body’s immune response against the new kidney. It can often be treated successfully if caught early, which is why monitoring and prompt reporting of symptoms matter so much. Other possible complications include infection, surgical problems such as bleeding, clots or leakage at the join, and side effects of the medicines. Over the longer term, immunosuppressants and the transplant itself can affect blood pressure, blood sugar and the risk of diabetes, and bone health, all of which the team watches for and manages. A transplanted kidney does not last forever, and some people eventually return to dialysis or consider another transplant; even so, many kidneys function well for a long time.
Living with a transplant
Living well with a transplant means taking the medicines reliably and on time, attending all follow-up appointments, and following the team’s advice on infection precautions and vaccinations. A healthy lifestyle helps protect the new kidney: not smoking, staying active, eating well, keeping to a healthy weight, and controlling blood pressure and blood sugar. Because the medicines raise skin-cancer risk, careful sun protection is important in Singapore’s climate. Food hygiene and avoiding contact with people who are unwell reduce infection risk. Many recipients also describe a strong emotional dimension — relief and renewed freedom, alongside gratitude to their donor and donor’s family, and sometimes anxiety about protecting the gift they have received. Support from the transplant team, the nephrologist, family and patient organisations such as the National Kidney Foundation can help.
When to seek urgent help
After a transplant, seek urgent medical care if you develop a fever or other signs of infection, notice a fall in the amount of urine you pass, feel pain or tenderness over the transplanted kidney, gain weight suddenly or become swollen, or simply feel unwell — these can be signs of rejection or infection that need prompt assessment. Do not wait to see if they pass. And never stop your anti-rejection medicines without specialist advice, even if you feel well or are unwell with something else; contact your transplant team instead.
When to see a doctor
People with advanced kidney disease should discuss transplantation early with their nephrologist, as being assessed and listed before dialysis (pre-emptive transplant) can offer the best outcomes.
Common questions
Is a transplant better than dialysis?
For suitable patients, a transplant generally offers better quality of life and survival, though it involves surgery and lifelong medication.
How long is the wait for a kidney in Singapore?
Deceased-donor waiting times can be long because demand exceeds supply; a living donor avoids the wait.
How long does a transplanted kidney last?
It varies, but many transplanted kidneys function well for many years; a living-donor kidney often lasts longer.
