Key Factors Influencing Kidney Transplant Success Rate: What You Need to Know

Asian Institute of Nephrology and Urology | April 2, 2025

Kidney transplant is a major surgical procedure that can impact a patient’s life in good way and even bad. Performed on individuals who suffer from chronic kidney disease or kidney failure, the success rate of this treatment is a critical factor, but one that is based upon multiple elements. The advancing medical sciences and technologies have massively enhanced the rate of success while also improving precision in treatment. Knowing the various factors that impact the kidney transplant success rate helps patients make informed decisions, and it's what we will explore here.

Factors Affecting Kidney Transplant

A number of factors come into play when determining the success rate of a kidney transplant treatment. The key factors that can dictate how likely the procedure is to succeed include the following:

1. Living Donor or Deceased Donor

The foremost determinant of the success rate of a kidney transplant is whether a patient gets a living donor transplant or a deceased donor transplant.

• Living donor transplants generally have a higher potential for success since the kidney to be transplanted is coming from a healthy living body. The healthier medical history of the donor contributes to the chance of success, with the rates going as high as 95% success during the first year. However, the rate of success in this period also depends upon how well the patient takes post-operative care. A great thing about this type of transplant is that it can be scheduled in advance.
• Deceased donor transplants, on the other hand, while still successful up to 85% to 90%, rely on deceased donors. As such, these kidneys can often be unhealthier as compared to those donated by a live person. This happens because the death causes a lack of supply of oxygen to the kidneys, from the time they are retrieved to the time they are transplanted. With proper care, the patient can witness a high success rate nevertheless.

2. Overall Health Of Recipient:

How successful a kidney transplantation process is also depends in large part on the overall health of the patient that is to receive the new kidney. A patient who does not maintain their health will experience a lower success rate and typically a higher chance of failure. Pre-existing medical conditions need to be monitored and kept under control, especially the following:

• Diabetes and blood pressure issues: These comorbidities can have a massive impact on the new kidney, damaging it rapidly in the time that your body tries to adjust to it and recover.
• Diseases of the Heart or Lungs: Patients suffering from cardiovascular diseases are likely to experience a lower success rate after kidney transplantation and have a higher chance of developing some complications during the surgery also.
• Compromised Immunity: A patient who has compromised immunity is more likely to develop infections, especially in the post-transplant recovery phase. Some may also have infections before the treatment, but in such cases, the transplant would normally be postponed until the infections are treated.

3. Donor-Recipient Compatibility

Another one of the key factors affecting kidney transplant is the compatibility between the donor and the receiver. Compatibility here refers to a blood type match and a tissue type match. Prior to the treatment, specialists will check specific parameters to assess whether the donor’s organ will be suitable or compatible with the receiver’s body. These checks include an assessment of the following:

• Blood Type Matching: If the donor and the receiver both have the same blood type, then the chance of success of the transplant is significantly increased than if they do not. This means that the chances of the kidney adjusting to the new body and functioning successfully are increased.
• HLA Match: HLA, or Human Leukocyte Antigen matching, is an important element to boosting the chances of success of the kidney transplant process. If the HLA matches, the success rate rises.
• Crossmatch Check: The crossmatch check or test is another important assessment done before the transplant process. This test checks whether or not the receiver’s immune system will accept the new kidney. This is essential because the immune system can start attacking the new kidney even immediately leading to irreparable damage.

4. Postoperative Care

How well a patient takes care of themselves and follows the doctor’s orders after the transplant is completed ,also plays a vital role in determining how successful the kidney transplant process will be. There are a number of medications prescribed to the patient after the completion of the procedure, along with detailed instructions about everyday care, do’s and don'ts, and the follow-up dates to ensure that the kidney is functioning optimally in the new environment. Failure to adhere to these guidelines leads to complications.

Medicines such as immunosuppressants are prescribed to ensure that the immune system does not attack or reject the new kidney. If the patient stops using them as prescribed, their immune system can start to reject the kidney.

Conclusion

Kidney transplant is a significant, life-altering surgical procedure that can have life-long implications for the patient if it does not succeed. The chances of success of the procedure, in modern times, are quite high, thanks to medical advancements and increased technological integrations. However, following proper pre- and post-operative care methods goes a long way in increasing chances of success. Along with this, other factors like the compatibility between the donor and receiver in specific parameters, the kind of donation, and multiple other factors come into play. Proper guidance before the procedure is thus necessary.
