In this study, we compare 2 cold storage conditions for transplantation using 31P CSI: Oxygenated pulsatile perfusion (O2+HPP) performed immediately after kidney harvesting vs. simple cold storage (CSS). We found that ATP did not fully recovered after 8 hours of CSS, and PME/Pi time constant was similar in both conditions (~0.05 h-1). Assessment of PME and ATP kinetics are important in the context of organ evaluation before transplantation as they may be considered as markers of kidneys viability.
