Histological features of stored kidneys after simple hypothermic perfusion with preserving solutions of different types

Four different preserving fluids were studied for protective effect in a total of 33 isolated canine kidneys. The preservation method consisted in initial perfusion followed by 24 hours of hypothermic storage. Two electrolyte and two non-electrolyte solutions were tested. One of the electrolyte solutions was of the extracellular, the other of the intracellular type. The two non-electrolyte solutions were 5% human albumin and 10% Rheomacrodex.
