Abstract. The study was carried out to investigate the composition and type of different urinary stones upon application of extracorporeal shock wave lithotripsy. ATR FTIR spectra revealed the marker bands of a mixed stone composition containing calcium oxalate monohydrate/ calcium carbonate, respectively calcium oxalate monohydrate/cystine. The surface morphology of the samples and elemental analysis was performed by SEM-EDAX confirming the presence of oxalate, carbonate and cystine in the samples. Combination of FTIR spectroscopy and SEM-EDAX allowed quantitative and qualitative evaluation of components, the spatial distribution and the percent of major and trace elements present in a single sample.
Key words: urinary stones, lithotripsy, FTIR spectroscopy, SEM-EDAX.
