Kidney stones analysis by ICP-OES

Abstract

Abstract The elemental composition of 100 oxalate type (only whewellite, weddellite and their mixture) urinary stones was determined by ICP OES. The calcium content varies from 130 to 320 g/kg; phosphorus – from 1.6 to 28 g/kg; sodium – from 0.54 to 8.7 g/kg; Ba, Fe, K, Li, Mg, Sr and Zn – from 0.0002 to 2.0 g/kg. The correlation analysis (Spearman rank correlation) showed a very weak tightness of the relationship between the elements of Ca/Li; a weak bond tightness for the pairs of elements Ba/Ca, Ba/Mg, Ba/Sr; Ca/Fe, Ca/Na, Ca/Sr; Fe/Mg, Fe/P, Fe/Sr, Fe/Zn; Li/Mg; Mg/Sr, Mg/Zn; P/Zn; average bond tightness for pairs of elements Ca/Mg, K/Na, Mg/P. All these correlations are positive.
