Autoregulation of renal blood flow was demonstrated in the autotransplanted kidney after various methods of preservation. In the transplanted kidney, as in the normal kidney, autoregulation was maintained to a tissue pressure of 30 mm Hg and then was progressively abolished as the tissue pressure rose. Autoregulation of renal blood flow may be a more sensitive parameter in assessing preservation techniques than simple renal blood flow. The fact that in this present study hypothermia and hyperbaric oxygen in combination showed preservation of autoregulation after 4 h storage while hypothermia alone did not sustain autoregulation suggests the former may be a more effective method of storage.
