MICROANALYSIS OF CALCIUM-RICH HUMAN KIDNEY-STONES AT THE NAC NUCLEAR MICROPROBE

Previous studies on the role of trace elements (TE) in the development of calcium oxalate (CaOx) human kidney stones by nuclear microprobe ( NMP) investigated the mechanisms and role of TE in the buildup of urin ary CaOx concretions. In the present work, microanalysis of the previo usly reported series of recurrent human kidney stones was further expa nded. Interest was focused on determining levels of directional variab ility in elemental concentrations of Ca and TE throughout selected mic ro-regions of single stones by Dynamic Analysis (DA).
