Peculiarities of sources of rudiments and morphogenesis of the pelvicalyceal system of the kidney in early period of the human prenatal ontogenesis

Abstract

Clarifying the sources of the rudiments, features of morphogenesis and syntopic changes of organs and body structures at an early period of human ontogenesis is an important task of anatomists, histologists and embryologists. A clear understanding of the sequence of the main stages of embryogenesis and the temporal dynamics of structural transformations of the urinary system sources in the intrauterine period of human development (IUD) will allow practicing doctors to clearly understand the features of the eriopathogenesis of malignant neoplasms of its organs and structures, to differentiate the remnants of embryonic tissues in the surgical material from tumors, to rationally apply the immunohistochemistry method in cancer diagnosis.
