An oxygen consumption assay using adenosine diphosphonucleotide (ADP) was performed on canine kidneys to measure the efficiency of oxidative phosphorylation. The purpose of the assay was to establish a respiratory control index (RCI) that could be used to evaluate kidneys preserved by different methods. Of the four methods tested, perfusion yielded the best results after 24-hour preservation. Additionally, four pairs of human cadaver kidneys were evaluated with the same assay. Some correlation existed between the RCI values of the nontransplanted kidney in each pair and the clinical viability of its transplanted mate.
