title: [Renal dysplasias].
abstract: The article presents an analysis of world literature on cysplasia of the kidneys (KD).  The authors consider as morphological characteristics the following signs: combination of primitive ducts, tubules, glomeruli, collecting tubules, cysts and immature mesenchyme with foci of cartilage and muscles.  An attempt is made to systematize individual forms of DK according to the degree of morphological changes (simple and cystic), extension (focal, segmental and total, mono- and bilateral) and localization (cortical, medullar and cortico-medullar or mixed) of the process.  From the group of cystic DK primary (aplastic and multicystic variants) and secondary (obstructive) ones were singled out.  The problems of morphology, incidence, complications, concomitant anomalies, causal and formal genesis of DK were also considered.
