Mass spectrometric trace element analysis of calcium oxalate uroliths.
Mass spectrometric trace element analysis of whewellite and weddellite uroliths revealed 55 elements, from which 20 could be well assessed quantitatively. The total trace element content in weddellite increased by 77.5% with respect to whewellite, the main portion being made up from Na, P, Mg, and Cl. In physiological conditions weddellite is stabilized by trace elements. The importance of trace element analysis of Si, Al, Sr, Rb, S, F, Cl, and Br in uroliths is indicated.
