The dual kidney transplant registry

Area of Science:

• Nephrology
• Transplantation Immunology
• Geriatric Medicine

Background:

• Aged donor kidneys are increasingly used for dual kidney transplantation.
• Long-term outcomes for these dual transplants are becoming clearer with accruing follow-up data.
• Kidneys outside standard acceptance criteria represent a valuable, often underutilized, resource.

Purpose of the Study:

• To evaluate the long-term graft survival of dual kidney transplants utilizing aged donor organs.
• To highlight the viability of using expanded criteria donor kidneys for transplantation.
• To identify critical factors influencing graft survival in this population.

Main Methods:

• Analysis of long-term graft survival data in recipients of dual kidney transplants from aged donors.
• Comparison of survival rates with historical data from single kidney transplants using younger donors.
• Assessment of factors potentially impacting graft longevity, including cold ischemic time.

Main Results:

• Long-term graft survival in dual kidney recipients from aged donors approaches that of single kidney recipients from younger donors.
• Properly transplanted aged donor kidneys demonstrate excellent long-term function.
• Reducing cold storage time is identified as a crucial factor for optimal graft survival.

Conclusions:

• Dual transplantation with aged donor kidneys is a viable strategy, offering excellent long-term function.
• Expanded criteria donor kidneys are a valuable resource that should be considered for transplantation.
• Minimizing cold storage time is paramount for maximizing graft survival in dual aged kidney transplants.
