STUDIES ON THE APPLICATION OF MICROEXPLOSION TO MEDICINE AND BIOLOGY

III. Amino Acids in Urinary Calculi

Abstract

As one of the fundamental researches for the development of microexplosion lithotripsy, amino acid analyses were performed on 12 dry urinary calculi. The results are as follows:
1) The weight of protein in dry calculi was from 0.53 to 3.15%. The mean was 1.6%.
2) Almost all amino acids in calculi were assumed to be the components of protein.
3) Regardless of inorganic component, calcigerous calculi had a similar pattern of amino acid composition, while uric acid calculus had a quite different pattern.
4) If protein should be added as to the materials to make a calculus model, fibrin would be the best from various points of view.
