A donor nephrectomy is a surgical procedure to remove a healthy kidney from a live donor for transplant into a person whose kidneys no longer function properly.

The kidneys are two bean-shaped organs located on each side of the spine just below the rib cage. Each one is about the size of a fist. Their main function is to filter and remove excess waste, minerals and fluid from the blood by producing urine.

You can donate one of your two kidneys, and the remaining kidney is able to perform the necessary functions, which makes living-donor kidney transplant an alternative to deceased-donor kidney transplant.

People with end-stage kidney (renal) disease need to have waste removed from their bloodstream via a machine (dialysis) or a kidney transplant to stay alive.

The first successful organ transplant in the U.S. was made possible by a living kidney donor in 1954 and used traditional (open) surgery for the kidney donation surgery. Currently, the vast majority of kidney donation surgeries are performed using minimally invasive laparoscopic techniques, and some also use robot-assisted technology.

Live kidney donation via donor nephrectomy is the most common type of living-donor procedure. About 5,000 living kidney donations are reported each year in the U.S.

Mayo Clinic's approach

Why it's done

Donor nephrectomy preparation at Mayo Clinic Donor nephrectomy preparation at Mayo Clinic

As a living kidney donor, you will have your own donor advocate and medical team to address any questions or concerns during the donor nephrectomy process.

Live kidney donation via a donor nephrectomy offers an alternative to waiting for a deceased-donor organ to become available for people in need of a kidney transplant.

A kidney transplant is usually the treatment of choice for kidney failure compared with a lifetime on dialysis.

The use of donor nephrectomy for live kidney donation has increased in recent years as the number of people waiting for a kidney transplant has increased dramatically. The demand for donor kidneys far outweighs the supply of deceased-donor kidneys, which makes living-donor kidney transplant an attractive option for people waiting for a deceased-donor kidney to become available.

In addition, living-donor kidney transplants are associated with several benefits for the recipient, including fewer complications and longer survival of the donor organ than in deceased-donor transplants.

Types of live kidney donation

You may choose to donate your kidney in one of two ways:

  • Directed donation. In directed donation, you name a specific recipient for transplant. This is the most common type of living-donor organ donation.
  • Nondirected donation. In a nondirected donation, also known as good Samaritan or altruistic donation, you do not name the recipient of the donated organ. The match is based on medical need and compatibility.

In a directed donation, if you and your intended recipient have incompatible blood types or are otherwise not a suitable match, paired-organ donation (paired exchange) or donation chain programs may be an option.

In paired exchange donation, two or more organ-recipient pairs trade donors so that each recipient gets an organ that is compatible with his or her blood type. A nondirected living donor also may participate in paired-organ donation to help match incompatible pairs.

More than one pair of incompatible living donors and recipients may be linked with a nondirected living donor to form a donation chain in order to receive compatible organs. In this scenario, multiple recipients benefit from a single nondirected living donor.


The risks associated with donor nephrectomy those associated with the surgery itself, the remaining organ function and the psychological aspects involved with donating an organ.

For the kidney recipient, the risk of transplant surgery is usually low because it is a potentially lifesaving procedure. But kidney donation surgery can expose a healthy person to the risk of and recovery from unnecessary major surgery.

Immediate, surgery-related risks of donor nephrectomy include pain, infection, hernia, bleeding, blood clots, wound complications and, in rare cases, death.

Living-donor kidney transplant is the most widely studied type of living organ donation, with more than 50 years of follow-up information. Overall, studies show that life expectancy for those who have donated a kidney is the same as for similarly matched people who haven't donated.

Some studies suggest living kidney donors may have a slightly higher risk of kidney failure in the future. But this risk is still smaller than the average risk of kidney failure in the general population.

Specific long-term complications associated with living kidney donation include high blood pressure and elevated protein levels in urine (proteinuria).

Donating a kidney or any other organ may also cause mental health issues, such as symptoms of anxiety and depression. The donated kidney may fail in the recipient and cause feelings of regret, anger or resentment in the donor.

Overall, most living organ donors rate their experience as positive.

To minimize the potential risks associated with donor nephrectomy, you'll have extensive testing and evaluation to ensure you're eligible to donate.

How you prepare

Making an informed decision

Donor nephrectomy consultation at Mayo Clinic Donor nephrectomy consultation at Mayo Clinic

Your transplant center is required to inform you of all the potential benefits and risks involved in becoming a living organ donor.

Making the decision to donate a kidney is a personal one that deserves careful thought and consideration of both the serious risks and benefits. Talk through your decision with your friends, family and other trusted advisers.

You should not feel pressured to donate, and you may change your mind at any point.

The Centers for Medicare and Medicaid Services and the Organ Procurement and Transplantation Network (OPTN) require that living-donor transplant centers provide an independent living-donor advocate to protect the informed consent process. This advocate is often a social worker or counselor who can help you discuss your feelings, answer any questions you have and assist in protecting your best interests throughout the donation process.

General criteria for kidney donation include:

  • Age 18 years or older
  • General good health
  • Two well-functioning kidneys
  • A willingness to donate
  • No history of high blood pressure, kidney disease, diabetes, certain cancers, or major risk factors for heart and blood vessel (cardiovascular) disease
  • Completion of a thorough physical and psychological evaluation at the transplant center

If you meet eligibility requirements to be a living donor, the transplant center is required to inform you of all aspects and potential results of organ donation and receive your informed consent to the procedure.

Choosing a transplant center

Your physician or your living-donor kidney recipient's physician may recommend a transplant center for your donor nephrectomy.

You're also free to select a transplant center on your own or choose a center from your insurance company's list of preferred providers.

When considering a transplant center, you may want to:

  • Learn about the number and type of transplants the center performs each year
  • Ask about the transplant center's organ donor and recipient survival rates
  • Compare transplant center statistics through the database maintained by the Scientific Registry of Transplant Recipients
  • Assess the center's commitment to keeping up with the latest transplant technology and techniques, which indicates that the program is growing
  • Consider additional services provided by the transplant center, such as support groups, travel arrangements, and referrals to other resources
  • Find out if the transplant center participates in paired-organ donation or donation chain exchange programs

What you can expect

In a donor nephrectomy, your procedure is scheduled for the same day as the transplant surgery for the recipient.

Before the procedure

Once you've gone through the living organ donor screening, evaluation and informed consent process, your donor nephrectomy procedure will be scheduled for the same day as the transplant surgery for the recipient. Separate medical teams and surgeons normally perform the donor nephrectomy transplant surgery, but they work closely together.

You'll receive instructions about what to do the day before and the day of your kidney donation surgery. Make note of any questions you might have, such as:

  • When do I need to begin fasting?
  • Can I take my prescription medications?
  • If so, how soon before the surgery can I take a dose?
  • What nonprescription medications should I avoid?
  • When do I need to arrive at the hospital?

During the procedure

Donor nephrectomy is performed with general anesthesia, so you're not aware during the procedure. The surgical team monitors your heart rate, blood pressure and blood oxygen level throughout the procedure.

Surgeons almost always perform minimally invasive surgery to remove a living-donor's kidney (laparoscopic nephrectomy) for a kidney transplant. Laparoscopic nephrectomy is associated with less scarring, less pain and a shorter recovery time than is traditional open surgery to remove a kidney (open nephrectomy).

In a laparoscopic nephrectomy, the surgeon usually makes two or three very small incisions close to the bellybutton, which are used as portals (ports) to insert the fiber-optic surgical instruments. The equipment includes a small knife, clamps and a special camera called a laparoscope that is used to view the internal organs and guide the surgeon through the procedure.

A slightly larger incision is made below the bellybutton to remove the donor kidney.

In open nephrectomy, a 5- to 7-inch (13-to18-centimeter) incision is made on the side of the chest and upper abdomen and a retractor is often used to spread the ribs to access the donor's kidney.

Both types of procedures are performed using general anesthesia, which means you'll be asleep during the entire surgery, and last about two to three hours.

After the procedure

After your donor nephrectomy, you'll likely stay in the hospital for one or two days.

In addition, you can expect:

  • Care after your surgery. If you live far from your transplant center, your doctors will recommend that you stay close to the center for a few days after you leave the hospital so that they can monitor your health and remaining kidney function.

    You'll likely need to return to your transplant center for follow-up care, tests and monitoring several times after your surgery. Transplant centers are required to submit follow-up data at six months, 12 months and 24 months after donation. Your local health care provider may conduct your laboratory tests one and two years after your kidney surgery.

  • Recovery. Depending on your overall health, doctors will give you specific advice on how to take care of yourself and reduce the risk of complications during your recovery, including avoiding sitting or lying in bed for long periods of time, not driving a car for one to two weeks, not lifting any objects heavier than 10 pounds (4.5 kilograms) for a month, caring for your incision, managing pain, and returning to a normal diet.
  • Return to normal activities. After kidney donation, most people are able to return to normal daily activities after two to four weeks. You may be advised to avoid contact sports or other strenuous activities that may cause kidney damage.
  • Pregnancy. Kidney donation normally does not affect the ability to become pregnant or complete a safe pregnancy and childbirth. Some studies suggest kidney donors may have a small increase in risk of pregnancy complications such as gestational diabetes, pregnancy-induced hypertension, preeclampsia and protein in the urine.

    It's usually recommended that women wait at least six months to a year after living donation before becoming pregnant.

  • Research. Mayo Clinic researchers actively study the health of donors after transplant surgery to improve results. At Mayo Clinic, you may have access to ongoing clinical trials, research and new treatments as part of your living-donor transplantation experience.

Coping and Support

Becoming a living donor is a deeply personal decision that requires careful consideration of both the serious risks and benefits. Reaching out to family members, friends, counselors, clergy or people who have gone through this process can be helpful.

Your Mayo Clinic transplant team also can assist you with other useful resources and coping strategies throughout the kidney donation and donor nephrectomy process, such as:

  • Joining a support group for organ donors. Talking with others who have shared your experience can ease fears and anxiety.
  • Sharing your experiences on social media. Mayo Clinic has a Facebook page called Transplantation at Mayo Clinic.
  • Educating yourself. Learn as much as you can about your procedure and ask questions about things you don't understand. Knowledge is empowering.

Diet and nutrition

You should be able to go back to your normal diet soon after the kidney donation surgery.

Unless you have other health issues, you won't likely have any specific dietary restrictions related to your procedure.

Your Mayo Clinic transplant team includes a dietitian who can discuss your specific diet needs and questions with you.


Maintaining a healthy lifestyle through diet and exercise is just as important for living-organ donors as it is for everyone else.

You can usually return to your normal physical activity levels within a few weeks or months after living-donor surgery. Your Mayo Clinic transplant team can discuss your individual physical activity goals and needs with you.

It's important to talk with your health care provider before starting any new physical activity.

Some doctors recommend living-kidney donors protect the remaining kidney by avoiding contact sports, such as football, boxing, hockey, soccer, martial arts or wrestling, and wearing protective gear such as padded vests under clothing to protect the kidney from injury during sports.
