Kidney Transplant

Kidney transplantation is performed by placing a healthy kidney taken from a living or deceased donor when a person’s kidneys do not function properly. The kidneys, which are located on both sides of the spine in each individual, are found just below the rib cage. The primary function of the kidneys is to produce urine and cleanse the blood of waste substances. When the kidneys lose this filtering capacity, the level of waste in the body increases. As a result, kidney failure develops, leading to serious health problems that can affect the entire body and require renal replacement therapies such as dialysis or kidney transplantation to sustain life.

Key Takeaways

• Kidney transplantation replaces a failed kidney with a healthy one from a living or deceased donor, offering a life-saving treatment for end-stage kidney failure.
• Compared to dialysis, kidney transplantation provides better long-term survival, improved quality of life, and greater independence.
• Successful transplantation depends on careful donor–recipient matching, thorough pre-transplant evaluation, and strict post-transplant follow-up.

What is a Kidney Transplant?

Kidney transplant is a type of surgery that involves replacing a kidney that has lost its function with a healthy kidney taken from a donor. The kidney can be obtained from a deceased organ donor or from a living donor and transplanted into the recipient. Family members or other individuals who show a suitable match may donate one of their kidneys. Such transplants are referred to as living donor transplants. Individuals who donate a kidney can continue to live a healthy life with a single healthy kidney.

What Are the Types of Kidney Transplantation?

Kidney transplantation is performed to improve the quality of life of patients with end-stage kidney failure. The type of transplant varies depending on the source of the kidney or the donor.

The types of kidney transplantation can be listed as follows:

Living Donor Kidney Transplantation

This involves the transplantation of a kidney obtained from a relative of the patient or a voluntary donor. Since tissue compatibility is generally better, success rates are higher, and the procedure can be planned in advance.

Deceased Donor Kidney Transplantation

This type of transplant is performed using kidneys obtained from individuals who have been declared brain-dead and have consented to organ donation. The waiting period may be long, and the preservation time of the organ can affect outcomes.

Kidney Transplantation from a Non-Related Living Donor

This transplant is carried out using a kidney donated voluntarily by a person who has no familial relationship with the recipient. Ethical and legal evaluations are conducted with great care.

Paired (Cross) Kidney Transplantation

If there is blood group or tissue incompatibility between the donor and the recipient, transplantation is performed through a reciprocal exchange with another donor–recipient pair. With appropriate matching, the likelihood of successful transplantation is increased.

Who is Eligible for Kidney Transplantation?

Kidney transplantation is performed in patients with end-stage kidney failure whose renal function has irreversibly declined. Individuals whose general health status is suitable for surgery and long-term treatment are considered for evaluation. The decision for transplantation is made by a multidisciplinary team following comprehensive medical assessments.

• Patients in the final stage of chronic kidney failure
• Patients undergoing dialysis or those for whom dialysis is planned
• Individuals who can tolerate general anesthesia
• Patients without active malignancy or uncontrolled infection

From whom can a kidney be obtained for transplantation?

A kidney can be obtained from living donors or from deceased donors who have been declared brain-dead. The donor’s overall health status, kidney function, and ethical and legal criteria are carefully evaluated. The primary goal is to ensure a safe process for both the recipient and the donor.

• First-degree relatives (mother, father, siblings)
• Second- and third-degree relatives
• Non-related voluntary living donors
• Deceased donors with confirmed brain death

What Are the Risks of Kidney Transplantation?

As with any surgical procedure, kidney transplantation involves certain risks. These risks may be related to the surgical procedure in the early period or to immune system–related complications in the long term. Regular follow-up and strict adherence to medication significantly reduce these risks.

• Risk of infection
• Rejection of the transplanted kidney by the body
• Bleeding and vascular complications
• Side effects related to immunosuppressive medications

Before Kidney Transplantation

Prior to kidney transplantation, the patient undergoes a comprehensive evaluation. The aim is to determine whether the surgery can be performed safely and whether the post-transplant process is likely to be successful. During this period, both the patient and the potential donor are prepared.

• Blood group and tissue compatibility tests
• Cardiac, pulmonary, and general health assessments
• Screening for infections and malignancies
• Detailed information provided to the patient and family about the process

After Kidney Transplantation

The post-transplant period is critical to the success of the treatment. Patients are required to attend regular follow-up visits and take their medications as prescribed. Lifestyle modifications play a significant role in improving long-term outcomes.

• Regular use of immunosuppressive medications
• Careful monitoring for signs of infection
• Routine medical follow-ups and blood tests
• Adoption of healthy dietary and lifestyle habits

Frequently Asked Questions About Kidney Transplantation

Who cannot donate a kidney?

Individuals with serious heart disease, active infections, cancer, or impaired kidney function cannot be kidney donors. Psychological suitability and legal eligibility are also required.

What is blood group compatibility in kidney transplantation?

In kidney transplantation, compatibility between the blood groups of the donor and the recipient is required. Appropriate compatibility reduces the risk of rejection of the transplanted kidney.

What are the benefits of kidney transplantation?

Kidney transplantation provides a longer and higher-quality life compared to dialysis. It increases independence in daily life and eliminates many limitations associated with chronic treatment.

What is the disadvantage of dialysis compared to kidney transplantation?

Dialysis requires regular sessions several times a week and significantly limits quality of life. In the long term, it may increase the risk of additional conditions such as cardiovascular diseases.

Can patients with diabetes undergo kidney transplantation?

Patients with diabetes may undergo kidney transplantation after appropriate evaluations. Adequate control of diabetes contributes positively to transplant success.
