Influence of calciuria on the urine stones genesis

Introduction. Hypercalciuria (HCU) is one of the main metabolic lithogenic disorders caused urolithiasis. Considering the significant role of calcium in the pathogenesis of urolithiasis, the proven effect of HCU on the initiation of stone formation during urolithiasis, it was decided to study the effect of calciuria on the frequency of formation of urinary stones of various chemical composition. Materials and methods. Material for the study - results of the chemical composition analysis of708 urinary calculi from 303 men and 405 women from the age of 16 to 78 years. The study was conducted retrospectively. All patients underwent an analysis of the chemical composition of urinary stone and a biochemical analysis of daily urine. Method of dividing the ranked variation series of calciuria into 10 ranges was used to assess the effect of the degree of calciuria on the frequency of calculi detection. Each range had from 64 to 75 observations. Results and its discussion. HCU with an excretion level of more than 4...
