Water-soluble crystals in structure of urine acid urolitae

For the first time in urine acid urolith, water-soluble crystals sylvite and halite of cubeoctahedron forms and mixed crystals which structure corresponds to chloride of sodium- potassium, are found out. The water-soluble phases containing sulfate potassium and sulfate of sodium- potassium are fixed. It is shown that the growth of halite, sylvite and syntactically fusing crystals is possible both in vivo, and in vitro as a result of evaporation. The sources of mineral formation genesis of water-soluble crystals in uroliths are discussed.
