[The etiological and pathogenetic bases of nephrolithiasis]. / Etiologicheskie i patogeneticheskie osnovy nefrolitiaza.

A new outlook on etiology and pathogenesis of nephrolithiasis regards renal tubular acidosis (RTA) as the basic pathogenetic factor of nephrolithiasis. These conclusions were made basing on the findings on blood and urine glycolysis enzymes, lactic acid, acid-base metabolism, titrated acids, ammonium. RTA stages responsible for the variety of the forming concrement and two groups of nephrolithiasis etiological factors (acting on epithelial cell of the nephron and involved in urinary processes) are distinguished.
