Function of human autologous kidney grafts after extracorporeal preservation with Sacks' II solution.

ABSTRACT

The function of 18 human kidney grafts was studied before and 3 months after autotransplantation without prior bench surgery on the parenchyma or the vessels. Kidney protection was accomplished by pre-treating the patient with mannitol and low molecular weight dextran solution and flushing the kidney with a Xylocaine-heparin mixture and cold Sacks' II solution. The mean cold ischaemia time was 239 min (range 140-345 min). The glomerular filtration rate (GFR) remained unchanged post-operatively in terms of both total and split kidney GFR. Proximal and distal tubular integrity, as studied by determination of beta2-microglobulin excretion and concentration ability respectively, was also preserved.
