Living donors often play an important role in paired donation and donation chains. Paired-organ donation also known as paired exchange may be an option when a donor and intended recipient have incompatible blood types, or when the recipient has unacceptable antibodies against the donor's tissue antigens. In paired 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.
In this scenario, multiple recipients benefit from a single nondirected living donor. Mayo Clinic's approach. Living-donor transplantation offers an alternative to waiting for a deceased-donor organ to become available for people in need of an organ transplant.
In addition, living-donor organ transplants are associated with fewer complications than deceased-donor transplants, and, overall, a longer survival of the donor organ. The risks associated with living-organ donation include both short- and long-term health risks associated with the surgical procedure, organ function and psychological problems following organ donation. For the organ recipient, the risk of transplant surgery is usually low because it is a potentially lifesaving procedure.
But donating an organ can expose a healthy person to the risk of and recovery from unnecessary major surgery. Immediate, surgery-related risks of organ donation include pain, infection, hernia, bleeding, blood clots, wound complications and, in rare cases, death. Long-term follow-up information on living-organ donors is limited, and studies are ongoing. Overall, available data shows organ donors fare very well over the long term. Donating an organ may also cause mental health issues, such as symptoms of anxiety and depression. The donated organ may fail in the recipient and cause feelings of regret, anger or resentment in the donor.
The known health risks associated with living-organ donation vary according to the type of donation. To minimize risks, you'll need to have extensive testing to ensure you're eligible to donate. 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 the life expectancy for those who have donated a kidney is the same as for similarly matched people who haven't.
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. The risks of living liver donation also are low, but experience with this procedure is more limited because it was introduced into medical practice more recently than kidney donation. The first living-donor liver transplant was performed in As with any surgical procedure, living liver donation may involve surgical complications, such as infection, bleeding, blood clots and, in rare cases, death.
Living liver donation may also cause bile leakage, narrowing of the bile duct, intra-abdominal bleeding and, in rare cases, inadequate growth of the remaining part of the liver.
Making the decision to donate an organ 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. Making the decision to donate is an individual one.
You should not feel pressured to donate, and you may change your mind at any point. Your medical information is kept confidential by the transplant center. If you are rejected as a donor during the evaluation process, the donor is told only that your organ was declined.
It is up to you whether you tell the recipient if known the reason if you chose to do so. 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.
Your physician or your recipient's physician may recommend a transplant center for your procedure. 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. If you're committed to donating an organ, your transplant team will partner with you and your local health care provider throughout the living-donor transplantation process. If possible, bring a family member or friend with you for your evaluation and surgery.
It may be helpful for you to discuss your decision to donate with a family member or friend. Living-organ donors are generally between the ages of 18 and 60 and in good health. Specific living-donor eligibility standards vary by organ and transplant center. Physical examination and psychological evaluation. At the transplant center, a transplant team will evaluate your general physical and mental health to make sure that undergoing living-donor surgery will pose minimal risks to you.
Doctors will perform tests to look for pre-existing conditions that may disqualify you from being a donor, such as diabetes, cancer, some infectious diseases, heart diseases or other conditions. If you are participating in directed donation, different transplant team members will perform evaluations and surgeries for you and your recipient. Your evaluation is confidential. Also, during the evaluation the team will check to ensure that the organ you're planning to donate is healthy and that removing either one of your kidneys or a portion of your liver is unlikely to cause health problems later in life.
This may include laboratory and imaging tests. Consent and final review. 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. Transplant staff will discuss with you and your family the benefits and risks of donating a kidney or a portion of your liver and answer your questions.
Staff will also discuss the importance of maintaining a healthy lifestyle before and after donating an organ. In a laparoscopic nephrectomy, the surgeon makes two or three small incisions close to the bellybutton and uses a special camera called a laparoscope to view the internal organs and guide the procedure. The donor kidney is then removed and transplanted into the recipient.
Surgeons almost always perform minimally invasive surgery to remove a living-donor's kidney laparoscopic nephrectomy for a kidney transplant, which involves less pain and a shorter recovery than traditional open surgery to remove a kidney open nephrectomy. M,; M. Pathological Technique.
