Abstract

Eight kidney stones obtained from a single patient over a period of about eleven years were analysed in its natural form by Rutherford backscattering with 2 MeV He-4+ ions, PIXE with 3 MeV protons, and PIGE with 4.5 MeV protons using the newly installed nuclear microprobe at Faure. Since the mechanism of kidney stone nucleation and growth is stillpoorly understood, it was of interest to establish whether kidney stones from a single patient were constant in composition as regards trace element content and whether the type of stone is reproduced on new stones grown after the removal of existing stones. As expected, the stones were rich in Ca. The matrix was calcium oxalate. Light elements present in minor concentrations were P, S, Cl and K. Trace elements werein very low concentrations, and the presence of Fe, Ni, Cu, Zn, Se, Br, Rb, Sr and Pb were recorded. Trace element trends in the stones, analysed with micro beams were identified. A good positive correlation between Sr and Zn was observed.
