Canine kidney preservation for 24 to 72 hours. Use of intracellular-like perfusate.

For universal application and usefulness, methods of renal preservation need simplification. Recent studies using initial brief perfusion with, and storage in, an intracellular, hyperosmolar type of perfusate have suggested the feasibility of this simple method. In the present study, 49 nephrectomized dogs received 16, 19 and 14 renal autografts preserved for 24, 48, and 72 hours, respectively, by this simple method. Long-term survivors in the three groups were seven of 16, ten of 19, and seven of 14, with return to normal or near-normal function. This method of preservation offers promise for wide clinical application in the near future.
