title: Microanalysis of calcium-rich human kidney stones at the NAC nuclear microprobe.
abstract: 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 urinary CaOx concretions. In the present work, microanalysis of the previously reported series of recurrent human kidney stones was further expanded. Interest was focused on determining levels of directional variability in elemental concentrations of Ca and TE throughout selected micro-regions of single stones by Dynamic Analysis (DA).
