A method and apparatus for treatment of chronic kidney disease (CKD), particular diabetic nephropathy, are disclosed. The method comprises activation of adenosine A2a receptors in parenchymal and immune cells infiltrated into kidneys. The activation is performed by PEMF (pulsed electromagnetic field) stimulation applied locally to kidneys. Adenosine A2a signaling pathway is a potent anti-inflammatory and immuno-suppressive regulator that has been proven to attenuate inflammation and injury in diabetic nephropathy. Efficient activation of A2a receptors is achieved by applying electromagnetic field stimulation consecutively in 3 spatial dimensions. This allows attaining a significant increase in activation of A2a receptors in comparison with one-dimensional stimulation. Assistant thermal stimulation may be applied to increase expression of heat shock proteins (HSPs) in parenchymal cells. HSPs improve protein functions, protect cells from apoptosis and necrosis, increase metabolism, and symbiotically enhance effects of electric stimulation on CKD.
