  • Title: [Short time in-situ preservation of the ischemic kidney by a simple initial hypothermic perfusion with various cold solutions. An animal experimental study].

    Journal: Urologe A; 1975 Jul; 14(4):199-204. PubMed ID: 1154570.
    Abstract:
    In unilateral nephrectomized beagle dogs the remaining kidney was subjected to 2 hrs of ischemia in situ. The ischemic organ was cooled to 22--23 degrees C by initial hypothermic perfusion over a 5-F catheter introduced into the renal artery via the carotid artery. It was then left in the open abdominal wound without any further attempts of cooling. Three perfusates were used: an isoosmolar Dextran solution (Eisenberger), a hyperosmolar, "intracellular" electrolyte solution (Sacks), and a hyperosmolar, "extracellular" electrolyte solution. There was a mean postoperative increase in serum creatinine levels of 0.6 mg-%. By the 3rd p.o. day at latest the serum creatinine was again within normal limits. The inulin and PAH clearances on the 7th and 14th p.o. day showed no significant differences to preoperative determinations. No definite advantage or disadvantage was noted among the three perfusates. All control dogs whose kidneys were made ischemic for 2 hrs without perfusion died due to acute tubular necrosis. Apparently the homogenous cooling and flushing by the initial perfusion is of more importance for good preservation in this situation than the composition of the perfusate.
