Living Donor Kidney Transplant

Introduction

If you have been told that your kidneys are failing and that a transplant may be the next step, you are likely facing a great deal of new information at once. A living donor kidney transplant is one of the main options doctors consider for people with advanced kidney disease. In this type of transplant, a healthy person — often a family member — gives one of their two kidneys to someone whose own kidneys can no longer do the job.

This article is written for people who already know they need a transplant, or are being evaluated for one, and for the family members who may be thinking about donating. It explains how the surgery works, how donors and recipients are evaluated, what recovery looks like, and what life afterwards involves. Both the recipient’s and the donor’s experience are covered, because in a living donor transplant there are always two patients.

What Is a Living Donor Kidney Transplant?

A living donor kidney transplant is a surgery in which a healthy person donates one of their kidneys to a person with kidney failure. The donor’s kidney is placed into the recipient’s body, where it begins to take over the work of filtering the blood and producing urine.

Compared with a transplant from a deceased donor, a living donor transplant generally allows the surgery to be planned in advance, often shortens the waiting time, and tends to produce kidneys that begin working sooner and last longer. These are the main reasons major transplant societies, including the American Society of Transplantation and KDIGO (Kidney Disease: Improving Global Outcomes), describe living donation as a preferred option when a suitable donor is available.

Why Is a Living Donor Kidney Transplant Performed?

A living donor kidney transplant is performed to treat end-stage kidney disease — the stage at which the kidneys have lost most of their function and can no longer keep the body healthy on their own. Without treatment, end-stage kidney disease is life-threatening.

Common conditions that lead to end-stage kidney disease include:

• Long-standing diabetes (the most common cause worldwide)
• High blood pressure
• Glomerulonephritis (inflammation of the kidney’s filtering units)
• Polycystic kidney disease (an inherited condition in which cysts grow in the kidneys)
• Autoimmune conditions such as lupus that damage the kidneys
• Congenital (from birth) kidney and urinary tract problems
• Long-term obstruction or reflux in the urinary system

When kidney function falls to roughly 10–15% of normal, the two main options doctors discuss are dialysis (a machine or fluid-based treatment that filters the blood) and transplantation. Current clinical evidence shows that a successful kidney transplant generally provides better long-term survival and quality of life than long-term dialysis. A living donor transplant, where one is possible, often produces the best outcomes among transplant types.

Who Is a Candidate?

The Recipient

You may be a candidate for a living donor kidney transplant if you have end-stage kidney disease or are approaching it. Doctors will look at:

• Your overall health, including heart and lung function
• Whether any active infections or cancers need to be treated first
• How well you are likely to tolerate surgery and anaesthesia
• Whether you can take and manage lifelong medications
• Your social and emotional support at home

Some patients can have a transplant before they ever start dialysis — this is called a pre-emptive transplant, and it is often associated with better outcomes. Others undergo transplant while already on dialysis.

Conditions that may delay or rule out transplant include active cancer, severe heart or lung disease, untreated infections, or situations where lifelong immunosuppressive medication would be unsafe. In many cases, problems found during evaluation can be treated first, and transplant can then be reconsidered.

The Donor

A living donor must be a healthy adult who freely chooses to donate. In India, the Transplantation of Human Organs and Tissues Act sets the legal framework for living donation. Donors are usually near relatives — parents, siblings, children (adult), spouses, and grandparents. Donation by someone who is not a near relative is permitted only under specific conditions and requires approval by an Authorisation Committee, which reviews the relationship and ensures donation is voluntary and not commercial.

To be considered, a potential donor should:

• Be a healthy adult, usually between 18 and 65 years of age
• Have two normally functioning kidneys
• Be free of conditions that could harm them after donation, such as diabetes, uncontrolled hypertension, significant kidney disease, or certain infections
• Be psychologically prepared and donating of their own free will
• Understand the risks and long-term implications of donation

Donor safety is the central concern of any living donor programme. If evaluation shows that donation would put the donor’s long-term health at risk, the transplant team will not proceed, even if the donor wishes to continue.

Alternatives to Living Donor Kidney Transplant

A living donor transplant is one option among several, and the right path depends on the individual situation, donor availability, and the patient’s overall health.

Deceased Donor Kidney Transplant

In a deceased donor transplant, the kidney comes from a person who has died and whose family has agreed to organ donation. Patients are placed on a waiting list and matched when a suitable kidney becomes available. Wait times can be long, sometimes several years, and the surgery itself usually cannot be scheduled in advance.

Haemodialysis

Haemodialysis uses a machine to filter the blood through a special filter outside the body. Most patients receive haemodialysis three times a week at a dialysis centre, with each session lasting around four hours. Some patients do haemodialysis at home, often more frequently.

Peritoneal Dialysis

Peritoneal dialysis uses the lining of the abdomen as a natural filter. A special fluid is placed inside the abdomen through a small catheter, and waste passes from the blood into the fluid, which is then drained out. This can be done overnight using a machine or by hand several times a day. It is generally performed at home.

Conservative (Non-Dialysis) Care

For some patients — particularly older patients or those with multiple serious medical conditions — intensive treatments like dialysis and transplant may not improve quality of life. In these situations, conservative care focuses on managing symptoms, slowing further damage, and maintaining the best possible quality of life without dialysis. This is a serious option that the kidney team, patient, and family discuss together.

Paired Kidney Exchange

When a willing donor is not a match for the intended recipient (because of blood type or tissue compatibility), a paired exchange may be an option. In a paired exchange, two or more donor–recipient pairs effectively swap kidneys, so each recipient receives a compatible organ. Programmes that arrange these exchanges are growing in India and many other countries.

Surgical Approaches

A living donor kidney transplant involves two operations happening close together: one to remove the kidney from the donor (called a donor nephrectomy), and one to place the kidney into the recipient (called the transplant operation).

Donor Surgery: Laparoscopic Donor Nephrectomy

Most living donor surgeries today are done using a laparoscopic (keyhole) approach. The surgeon makes several small incisions in the abdomen, inserts a small camera and instruments, and removes one kidney through a slightly larger incision. Compared with traditional open surgery, laparoscopic donor nephrectomy is associated with smaller scars, less pain, a shorter hospital stay, and faster return to normal activity. It has become the standard approach for living donors in experienced centres.

Donor Surgery: Robotic-Assisted Donor Nephrectomy

Some centres use a robotic-assisted laparoscopic approach. The surgeon controls instruments through a robotic console, which can offer very fine control. The outcomes for the donor are generally similar to standard laparoscopic surgery.

Donor Surgery: Open Donor Nephrectomy

An open donor nephrectomy uses a single larger incision in the side or lower abdomen. It is now used less frequently but may still be appropriate in certain anatomical situations.

Recipient Surgery: Standard Open Transplant

The recipient surgery is almost always done as an open procedure. The new kidney is placed in the lower right or left side of the abdomen, just above the groin. The donor kidney’s blood vessels are connected to the recipient’s blood vessels, and the ureter (the tube from the kidney to the bladder) is connected to the bladder. The recipient’s own kidneys are usually left in place unless there is a specific reason to remove them.

Recipient Surgery: Robotic-Assisted Kidney Transplant

Robotic-assisted kidney transplantation in the recipient is offered at some advanced centres and may be considered for selected patients. It involves smaller incisions and can offer benefits for some patients, particularly those with a higher body weight where wound complications are a concern. This approach is still less common than open recipient surgery.

Preparing for a Living Donor Kidney Transplant

Preparation is detailed and involves separate evaluations of the recipient and donor.

Recipient Evaluation

The recipient’s workup is designed to make sure transplant is safe and likely to succeed. It usually includes:

• Blood group and tissue typing (called HLA typing)
• Crossmatch testing — mixing recipient and donor blood to check for harmful antibodies
• Antibody screening (PRA — panel reactive antibodies)
• Kidney function tests and urine tests
• Heart evaluation, often including ECG, echocardiogram, and sometimes stress testing
• Chest imaging and lung function checks if needed
• Screening for hepatitis, HIV, tuberculosis, and other infections
• Age-appropriate cancer screening
• Dental evaluation to address any sources of infection
• Psychological and social assessment

Donor Evaluation

Donor evaluation is even more thorough, because the donor is a healthy person and their safety is paramount. It usually includes:

• Blood group and tissue compatibility testing
• Detailed kidney function tests, including measured or calculated GFR
• 24-hour urine collection to look at protein and overall filtering
• CT or MR angiography to map the kidney’s blood vessels
• Blood pressure assessment, sometimes over 24 hours
• Screening for diabetes, including a glucose tolerance test where indicated
• Screening for hepatitis, HIV, and other transmissible infections
• Cancer screening appropriate to age and sex
• Psychological assessment and independent counselling
• Review by an independent donor advocate, whose role is to look out only for the donor’s interests

Legal and Ethical Review

In India, both donor and recipient documents are reviewed under the framework of the Transplantation of Human Organs and Tissues Act. For near-relative donations, the documentation and relationship are verified. For donations from a donor who is not a near relative, the Authorisation Committee reviews the case to confirm the donation is voluntary and not commercial.

In the Days Before Surgery

Closer to surgery, both donor and recipient will:

• Meet the surgical and anaesthesia teams
• Receive instructions about food, drink, and medications before surgery
• Have updated blood tests and a final crossmatch
• Receive any vaccines the team recommends (often given earlier in the workup)

The recipient will also have a detailed discussion about the medications they will need to take after transplant, particularly the immunosuppressive drugs — medicines that lower the body’s immune response so it does not reject the new kidney.

What Happens During the Surgery

The Donor Operation

The donor receives general anaesthesia. The surgical team makes small incisions and uses a camera and instruments to carefully free the kidney from surrounding tissue. The artery, vein, and ureter are then divided and the kidney is removed through a slightly larger incision, usually low on the abdomen. The kidney is flushed with a cold preservation solution and kept on ice until the recipient is ready. The donor’s incisions are closed, and the donor is moved to recovery. The donor surgery typically takes around two to three hours.

The Recipient Operation

The recipient also receives general anaesthesia. A curved incision is made low in the abdomen. The donor kidney is placed in the pelvis. The surgeon connects the donor kidney’s artery and vein to the recipient’s blood vessels and attaches the ureter to the bladder. A thin internal tube (a stent) is usually placed in the ureter for a few weeks to help it heal. Once blood flow is restored, the kidney often begins producing urine on the operating table. The recipient operation typically takes around three to four hours.

Both donor and recipient are then moved to a recovery area and then to a specialised transplant ward or, in the recipient’s case, often to an intensive care unit for closer monitoring during the first day or two.

Recovery and Healing

Recipient Recovery in Hospital

Recipients usually stay in hospital for around one to two weeks, depending on how the new kidney is working and how recovery progresses. During this time, the team will:

• Monitor urine output and blood tests closely
• Adjust immunosuppressive medications based on blood levels
• Watch for early signs of rejection, infection, or surgical complications
• Remove drains, the urinary catheter, and eventually the ureteric stent (usually a few weeks later in a small outpatient procedure)
• Teach you about your medications, signs of trouble, and follow-up

Donor Recovery in Hospital

Donors typically stay in hospital for around three to five days after laparoscopic surgery. Most are walking the day after surgery and eating normally within a day or two. Pain is usually manageable with standard pain relief.

Recovery at Home: Recipient

After leaving hospital, recipients are seen frequently in the transplant clinic — sometimes two or three times a week at first, then less often as things settle. Light activity such as walking is encouraged early. Lifting heavy weights and strenuous exercise are usually avoided for six to eight weeks. Most recipients gradually return to normal daily activities over one to three months, with full return to work depending on the type of job.

Recovery at Home: Donor

Donors generally recover faster than recipients. Most return to office-type work in two to four weeks and to more physical work in around six weeks. Heavy lifting and contact sports are typically avoided for around six weeks. The remaining kidney enlarges over the following weeks and takes over much of the filtering work of two kidneys; this is a normal and expected change.

Risks and Complications

A living donor kidney transplant is a major surgery, and both donor and recipient face real, though usually manageable, risks. A thorough discussion of these risks is part of informed consent for both people.

Risks for the Recipient

• Rejection: The body’s immune system may try to attack the new kidney. Rejection is most common in the first months but can happen at any time. It is often detected early through blood tests and is usually treatable with adjustments in medication.
• Infection: Because immunosuppressive drugs lower the immune system, recipients are more vulnerable to infections, including viral infections such as cytomegalovirus (CMV) and BK virus.
• Bleeding and blood clots: As with any major surgery.
• Delayed graft function: The new kidney may take longer to start working; temporary dialysis can be needed.
• Surgical complications: Such as problems with the connection of the ureter to the bladder, leakage, or narrowing.
• Medication side effects: Immunosuppressive drugs can affect blood pressure, blood sugar, cholesterol, bone health, and increase certain cancer risks over time.
• Recurrence of the original disease: Some kidney diseases can affect the transplanted kidney.

Risks for the Donor

• Bleeding and surgical complications: Uncommon but possible.
• Infection: Of the wound or urinary tract.
• Blood clots: In the legs or lungs, particularly without early walking.
• Pain and fatigue: Usually temporary.
• Hernia: At the incision site, rarely.
• Long-term changes in kidney function: Donors lose some kidney function but the remaining kidney compensates well. Studies suggest a small increase in the long-term risk of high blood pressure, protein in the urine, and end-stage kidney disease compared with non-donors, but the absolute risk remains low when donors are well selected.
• Emotional impact: Donors can experience anxiety, particularly if the recipient’s outcome is not as hoped.

The risk of death from living donor nephrectomy is very low — estimated at roughly 3 in 10,000 donors based on international data — but it is not zero, and this is part of the conversation every donor must have with their team.

Life After a Living Donor Kidney Transplant

For the Recipient

Life after transplant generally feels much better than life on dialysis. Energy improves, dietary restrictions ease, and many people return to work, study, travel, and family life. However, the new kidney needs lifelong care.

Immunosuppressive Medication

Recipients take immunosuppressive medication for as long as the transplanted kidney works. These usually include a combination of two or three drugs, such as a calcineurin inhibitor (tacrolimus or ciclosporin), an antiproliferative agent (mycophenolate or azathioprine), and a corticosteroid (such as prednisolone), although protocols vary. Doses are highest at the start and reduced over time. Taking these medications exactly as prescribed is one of the most important factors in long-term success.

Follow-Up and Monitoring

Follow-up is intense in the first months and gradually becomes less frequent. Typical monitoring includes:

• Blood tests for kidney function, drug levels, blood sugar, and blood counts
• Blood pressure checks
• Urine tests for protein and infection
• Screening for infections such as CMV and BK virus in the early months
• Periodic assessment for diabetes, heart disease, and cancers (skin and others)
• Vaccinations — live vaccines are generally avoided, but other vaccines are encouraged

Diet, Exercise, and Daily Life

Most recipients can eat a normal, healthy diet, though limits on salt, certain foods such as grapefruit (which interacts with some immunosuppressants), and unpasteurised foods may apply. Regular moderate exercise is encouraged. Smoking is strongly discouraged, and alcohol should be limited and discussed with the team. Sun protection is important because of a higher risk of skin cancers.

For the Donor

Most donors return to fully normal lives. Long-term follow-up usually includes:

• Annual blood pressure checks
• Annual blood and urine tests for kidney function and protein in the urine
• Healthy lifestyle, with attention to blood pressure, weight, and avoiding nephrotoxic medications when possible

Pregnancy after donation is possible and generally safe with proper care; women planning pregnancy should discuss this with their kidney team.

Success Rates and Long-Term Outcomes

Living donor kidney transplants have, on average, the best outcomes among kidney transplant types. Key qualitative patterns from the international literature include:

• Most living donor transplants are working well one year after surgery.
• Living donor kidneys tend to last longer than deceased donor kidneys.
• Pre-emptive transplants (done before dialysis is started) tend to have better long-term outcomes than transplants done after long periods on dialysis.
• Younger, healthier donors and recipients generally do better, but excellent outcomes are achievable across a wide range of ages.
• Adherence to medication and follow-up is one of the strongest predictors of long-term success.

Specific numbers vary between centres, donor types, and individual situations. Your transplant team can give you a more personalised picture based on your own evaluation.

Living Donor Kidney Transplant in Children

Children with end-stage kidney disease can also receive a living donor kidney transplant, and outcomes in children are generally very good. The donor is often a parent.

Some considerations are specific to children:

• Causes of kidney failure in children are often different from adults, including congenital problems with the kidneys and urinary tract, inherited diseases, and certain glomerular diseases.
• Pre-emptive transplant (before starting dialysis) is often preferred when possible, because dialysis can affect a child’s growth and development.
• The surgery is performed at specialised paediatric transplant centres. The adult donor kidney is usually large enough to function well in a child; the surgical placement is adapted to the child’s anatomy.
• Growth, schooling, vaccinations, and psychological support are key parts of post-transplant care.
• Adolescents need particular support around medication adherence as they grow into independence; non-adherence is a recognised cause of late graft loss in this age group.

For families, a paediatric kidney team, including transplant surgeons, paediatric nephrologists, nurses, dietitians, social workers, and psychologists, provides care across the journey.

Frequently Asked Questions

Can a donor live a normal life with one kidney?

Yes. After donation, the remaining kidney enlarges and takes on more of the work, so overall kidney function settles at around two-thirds of what it was before donation. Most donors lead normal lives, including work, exercise, and pregnancy, with ongoing healthy lifestyle and regular check-ups.

How long does a transplanted kidney last?

A living donor kidney often functions well for many years, and many last well over a decade. Some last much longer. How long any individual kidney lasts depends on many factors, including the underlying disease, age, medication adherence, and any complications along the way.

Will the transplant cure my kidney disease?

A transplant replaces the function of the failed kidneys but does not always cure the underlying condition. For example, diabetes continues after transplant and still needs careful management. Some kidney diseases can recur in the transplanted kidney, although in many people this does not happen or is mild.

Will I need dialysis after the transplant?

If the new kidney works immediately, dialysis is no longer needed. If there is delayed graft function, dialysis may be needed for a short time until the new kidney starts working fully. In rare situations where the transplant fails, dialysis or another transplant may be considered.

How is donor and recipient compatibility determined?

Compatibility is checked using blood group testing, HLA tissue typing, antibody screening, and crossmatch testing. A perfect HLA match is not necessary for a successful transplant. When the intended donor is not directly compatible, paired exchange programmes or specialised treatments to reduce harmful antibodies may make transplant possible.

Can a donor change their mind?

Yes. A potential donor can withdraw at any point in the process, for any reason or no reason at all. Transplant teams support this and respect donor autonomy fully. The donor’s decision is kept confidential from the recipient if they wish.

How soon after transplant can the recipient return to work?

This depends on the type of work and individual recovery. Many recipients return to office-type work within two to three months. Physically demanding work generally takes longer. The transplant team will guide you based on your healing and overall health.

Is travel possible after transplant?

Yes, with planning. After the initial recovery period and once medications are stable, most recipients can travel, including by air. The team usually advises waiting several months before long trips, ensuring adequate medication supply, avoiding areas with high infection risk in the early months, and getting appropriate vaccinations well in advance.

Conclusion

A living donor kidney transplant is a major step that often offers significant gains in health and quality of life for people with end-stage kidney disease. It is also a step that depends on the generosity of another person — usually someone close to the recipient — and on careful evaluation that protects both donor and recipient.

Understanding what the surgery involves, what recovery looks like, the risks for both people, and what life afterwards requires can make this journey feel less overwhelming. Decisions about whether and when to proceed, which surgical approach to use, and how to plan follow-up are made together with a transplant team that knows your full medical picture. With careful preparation, modern surgical techniques, and steady long-term care, both donors and recipients can look forward to healthy lives after a living donor kidney transplant.
