Professor Zhao Yuyong is one of the first twelve famous Chinese medicine practitioners in Hebei province. He has been engaged in kidney disease research for more than 50 years and has rich clinical experience. Professor Zhao believes that the pathogenesis of idiopathic membranous nephropathy (IMN) is characterized by deficiency of the essence and excess of the essence, with deficiency of the spleen and kidney as the main deficiency, and the excess of the essence is the combination of wind, dampness, heat, blood stasis and toxin. This paper demonstrates the objectivity of "kidney collateral stasis" from the perspective of renal pathomorphology, and puts forward that the key to the pathogenesis of IMN is "kidney collateral stasis"; Based on the microscopic differentiation of symptoms and signs, it is considered that in the pathogenesis of IMN caused by podocyte injury caused by membrane attack complex, membrane attack complex is interlinked with pathogenic Qi coagulation in traditional Chinese medicine, and the treatment method of "supporting healthy Qi, eliminating pathogenic factors and dredging collaterals" is established. In the treatment of IMN, such as hypercoagulability, thrombophilia and massive proteinuria, the prescription is used in a unique way, and the method of "taking analogy" is used skillfully. Professor Zhao Yuyong‘s clinical experience in treating IMN is now analyzed.
