[In vivo determination of local tissue pO2 in renal cortex in kidney transplantation].

From measurement of local tissue PO2 in human kidney grafts after restoration of renal circulation, a correlation between initial microcirculation and kidney function can be drawn. PO2-histograms of kidney grafts with sufficient function are normal, whereas PO2-histograms of kidneys with delayed onset of function (congruent to 3 weeks) show distinct disturbances of microcirculation. These preliminary results suggest that measuring local tissue PO2 in transplanted kidneys may be of value for the prognosis of the graft.
