The main clinical symptoms of different stages of the nephrotic crisis are described, namely of the abdominal painful crisis, migrating erysipelas-like erythemas and the hypovolemic shock (collapse). The spectrum of diseases requiring the differential diagnosis with the nephrotic crisis is established. The complex of measures for the prophylaxis and treatment of the nephrotic crisis is proposed.
