[Unusual elements in renal calculi].
A group of 54 renal calculi were spontaneously passed renal stone after a nephritic colic. Two groups of calculi were found: papillary and non-papillary calculi. All calculi were analyzed by infrared spectroscopy and electronic microscopy scan (EMS) and EDAX. When the stones were analyzed with EDAX, elements such as C, N, O, Na, S, Mg, Al, Si, Cl, K, Ca, Mn, Fe, Ni, Zn were detected. The possible origin of these elements is discussed in this work.
