Regarding the issue of kidney transplantation in diabetic patients?

Hello Dr.
Hsiao, I have a question regarding a family member who has developed kidney disease due to diabetes and has been on dialysis for several years.
They are considering living kidney transplantation, so I would like to ask about the risks associated with the kidney transplant surgery.
Additionally, will the transplanted kidney function normally in the patient? How long can the transplanted kidney typically last? Thank you again for your response.
Best Regards.

Hello,
In response to your inquiry:
1.
Renal transplantation is a collaborative effort that requires the teamwork of urologists, nephrologists, anesthesiologists, and various other personnel.
Generally, patients who undergo renal transplantation are expected to have a longer lifespan and a normal quality of life.
Preoperative assessment is crucial to avoid transplant failure.
If there are unresolved issues with the vascular or urinary systems, the surgical risks will inevitably increase.
2.
According to a large study report developed by the USRDS in 1998, the one-year survival rate for deceased donor kidney transplants is 87%, and the three-year survival rate is 76% (based on 35,289 cases).
For living donor transplants, the respective rates are 92% and 83% (based on 2,153 cases).
3.
Post-transplant, patients must take immunosuppressive medications such as Prednisolone and Cyclosporine.
It is also important to monitor for the recurrence of pre-existing conditions, including diabetic nephropathy, chronic glomerulonephritis, and infections.
4.
My knowledge of renal transplantation is limited, so I recommend discussing this further with the renal transplantation teams at major hospitals.
Wishing you a speedy recovery.
Dr.
Hsiao Yong-Hsun, Family Medicine

More Info

Kidney transplantation can be a life-changing procedure for patients with diabetes who have developed kidney disease, particularly those on dialysis. However, it is essential to understand the associated risks, the potential for the transplanted kidney to function well, and the expected longevity of the transplant.

Risks of Kidney Transplantation
The risks associated with kidney transplantation for diabetic patients can be multifaceted. Firstly, the surgical procedure itself carries inherent risks, such as bleeding, infection, and complications related to anesthesia. For patients with diabetes, these risks can be heightened due to potential cardiovascular issues and impaired wound healing.
Moreover, diabetes can lead to vascular complications, which may affect the blood supply to the transplanted kidney. Pre-existing conditions, such as peripheral vascular disease, can also increase the risk of surgical complications. Therefore, a thorough preoperative assessment is crucial to evaluate the patient's overall health and the presence of any comorbidities that could complicate the surgery.

Post-Transplant Functionality
After a successful kidney transplant, the new kidney can function effectively, allowing the patient to regain a more normal lifestyle. However, the success of the transplant largely depends on several factors, including the patient's adherence to immunosuppressive therapy, the management of diabetes, and the absence of other complications.

Patients will need to take immunosuppressive medications to prevent rejection of the transplanted kidney. These medications can have side effects, including an increased risk of infections and potential impacts on blood sugar levels. Therefore, careful monitoring and management of diabetes post-transplant are essential to ensure the transplanted kidney functions optimally.

Longevity of the Transplanted Kidney
The longevity of a transplanted kidney can vary significantly based on several factors, including the type of donor (living vs. deceased), the patient's overall health, and how well the diabetes is managed post-transplant. According to data from the United States Renal Data System (USRDS), the one-year survival rate for deceased donor kidneys is approximately 87%, while for living donor kidneys, it is around 92%. The three-year survival rates are 76% for deceased donors and 83% for living donors.

In general, a well-functioning transplanted kidney can last anywhere from 10 to 20 years or more, depending on the factors mentioned above. However, it is important to note that diabetes can lead to complications that may affect the longevity of the transplant, such as recurrent diabetic nephropathy or other metabolic issues.

Conclusion
In summary, while kidney transplantation can offer a new lease on life for diabetic patients with kidney failure, it is not without risks. A comprehensive preoperative evaluation and careful postoperative management are crucial for optimizing outcomes. Patients must remain vigilant in managing their diabetes and adhering to their medication regimens to enhance the longevity of the transplanted kidney. Engaging in regular follow-ups with healthcare providers specializing in transplant care is essential for monitoring kidney function and overall health.
