The electrical bio-impedance signal obtained from kidney reflects the nature of renal blood circulation. This paper proposed a novel approach that can be used to diagnose the acute kidney allograft rejection, the method based on non-invasive electrical impedance measurement from cutaneous electrodes on skin surface.

Objective – create the fundamental basis for the development of a renal blood monitoring system based on electrical impedance measurements from cutaneous electrodes that can be used to diagnose the acute kidney allograft rejection.

Results. a) An appropriate biophysical model has been proposed for the dynamic calculation of electrical resistivity change of kidney, which allows determining the amount of blood per 100 G of kidney tissue; b) The results of multichannel mapping with different electrode systems had shown electrical impedance signal due to renal blood circulation as well as the effect of the blood filling of the surrounding tissues of the kidney. Achieve an optimal location of the electrode system relative to the projection of the kidney onto the surface of the skin as well as taking into the account the surrounding tissues contribution can improve the measurement accuracy.

Practical significance – development of renal blood monitoring system using bio-impedance measurement.
