title: [Substantiation and use of a new method of transorganic oxygen preservation of the kidneys].
abstract: A new method has been developed for effective normobaric transorganic oxygen preservation of the kidneys. According to this method, oxygen is insufflated simultaneously through an artery, a vein and a ureter. A portable autonomously-operated device has been developed and used successfully for its clinical application. In experimental conditions, transorganic oxygen preservation ensures viability of the preserved kidney for up to 48 hours, with immediate post-transplantation recovery of renal function, and for 72 hours, with delayed functional recovery. The success of transorganic oxygen preservation was controlled by cellular metabolism assessment. Changes in adenylic acid components, lactic acid and lipid peroxidation products were measured in renal tissue. In clinical conditions, the outcome of transplantation could be predicted with high probability on the basis of intraoperative transplant hemodynamic studies. Two groups of patients were compared: 43 patients to whom a cadaver kidney, preserved by transorganic oxygenation for up to 52 hours, was transplanted, and recipients of contralateral kidneys, obtained from the same donors and preserved in Eurocollins solution for not more than 26 hours without perfusion. Preservation by transorganic oxygenation was shown to be preferable when clinical results were analysed.
