title: Analysis of the optimal perfusion pressure and flow rate of the renal vascular resistance and oxygen consumption in the hypothermic perfused kidney.
abstract: Thirty-six dog kidneys were perfused with different perfusion pressures (between 15 and 60 mm. Hg) for 72 hours and then transplanted. Hypothermic human albumin was the perfusion fluid.  Enzyme release, kidney weight, and renal oxygen consumption were measured during perfusion. Kidneys perfused with a flow rate of 0.8 ml. per gram per minute (21 mm. Hg mean perfusion pressure) showed the smallest increase in kidney weight and the best function after transplantation. Renal vascular resistance was independent of the level of the perfusion pressure and renal oxygen consumption was independent of the applied flow rate. It is concluded that the perfusion pressure applied with hypothermic perfusion should be as low as possible because in this way kidney damage caused by perfusion can be avoided most easily.
