Keeping donated kidneys healthier longer with room-temperature oxygenated perfusion
Platform for Extended Kidney Preservation Via Subnormothermic Perfusion
This project tests a device and special solution that keep donated kidneys at about room temperature with oxygen flowing through them so more high-risk organs might be usable for people needing transplants.

What this research studies
If I'm waiting for a kidney transplant, this project aims to reduce damage that happens while a donated kidney is stored and moved by using a machine that pumps oxygenated solution through the organ at 22–25°C. The approach pairs a perfusion device with a matched preservation solution developed by BioMedInnovations and the Duke Ex Vivo Organ Lab. In animal (porcine) pilot work, this method improved how kidneys worked after transplant compared with standard cold storage. The team plans to refine the platform so more older or circulatory-death donor kidneys can be preserved, tested, and accepted instead of discarded.
Who could benefit from this research
Good fit: People on the kidney transplant waiting list or candidates preparing for transplant, especially those willing to consider higher-risk donor kidneys, are the intended beneficiaries.
Not a fit: People who do not need a kidney transplant or those ineligible for transplant would not directly benefit from this preservation technology.
Why it matters
Potential benefit: If successful, this could increase the number of usable donor kidneys and improve early transplant function for people on the waiting list.
How similar studies have performed: Early animal studies showed better post-transplant kidney function versus standard cold storage, but broader human testing is still needed.
