Signs of a Dying Organ: Beyond Resistance in Subnormothermic Kidney Perfusion.
M. Blum, D. Urcuyo, Q. Liu, B. Soliman, T. Okamoto, D. Goldfarb, C. Quintini.
Cleveland Clinic, Cleveland, OH.
Purpose: In hypothermic machine preservation of the kidney, resistance is often used to assess organ quality. Since no prognostic standard yet exists for subnormothermic ex-vivo…
