The maximum storage time for kidneys in cold storage solution, as recommended by the Association of Organ Procurement Organizations (AOPO), is indeed 24-36 hours. This timeframe is crucial for ensuring that the organs remain viable for transplantation. During cold storage, kidneys can function effectively in a low-temperature environment, which helps to preserve cellular metabolism and reduces the potential for damage.

Storing kidneys beyond this recommended time frame can lead to significant decline in quality and function due to factors like organ ischemia and reperfusion injury when the organ is ultimately transplanted. This guideline is established based on extensive research and clinical practice to optimize transplant outcomes.

While the other options suggest varying timeframes, they do not align with the established guidelines provided by AOPO regarding the optimal conditions for kidney preservation before transplantation.
