We reviewed the evidence for ex-vivo Supplemental Oxygen during Hypothermic preservation (SOH) for deceased donor kidneys. Bibliographic databases were searched for human and animal studies of SOH in kidney transplantation reporting on patient or animal survival rate, discard rate, technical complications or renal function outcomes. We make special reference to a specific subgroup: supplemental oxygen applied during cold perfusion, referred to as Hypothermic Oxygenated Perfusion (HOP). Four human and 25 animal studies were identified. The data present conflicting results but suggest that the effects of oxygen on restoring kidney function during preservation may be of value for DCD kidneys and/or kidneys that have undergone a period of hypotension, warm ischemia or poor perfusion in the donor. There is very little information available from human or animal studies. This work highlights to the transplant community that far more high quality clinical studies are required to understand this technology and its role before widespread clinical introduction.
