Zuzuk F. Mineralogy of Urolites.

Based on vast statistical data about spreading of urinary stone disease both in the world in general and in Ukraine in particular, the author states that the phenomenon bears local-regional peculiarities and is caused by such factors as social-economical, pollution of the environment, climatic, hydrochemical peculiarities of the drinking water and geological one. Associations of continuous rows are the most widespread ones, to which belong such associations as apatite-struvite, whewellite-apatite, weddelite-apatite and weddelite-whewellite. Peculiarities of individuals and aggregates of stone forming minerals correspond to such of geological formations. It has been proved that urolites are formed as the result of sedimentation, crystallization and vital activity of microorganisms.
