Description and interpretation of functional changes in canine kidneys after preservation with hypothermic perfusates and subsequent reperfusion.
The function of canine kidneys stored with hypothermic solutions (Rheomacrodex, Collins4, Sacks) was studied in acute autologous reperfusion models. Changes in the perfusates (increase in LDH level and minor increase in K+ level), as well as the quantitative and qualitative properties (proteinuria) of the urine produced by the graft may be ascribed to storage and revascularization which affect the cells and their membranes. The alterations of the circulatory parameters demonstrable at the outset and during revascularization are due to an increase in renovascular resistance of hypothermic origin on the one hand, and to acute tubular epithelial damage inherent in the procedure, on the other.
