    Abstract:
    Using thermoluminescence spectrometer, X-ray diffraction and Fourier transform infrared spectroscopy, the chemical compositions of four types of kidney stones were investigated. They are calcium oxalate, uric acid, calcium phosphate and magnesium ammonium phosphate calculi (struvite). Experimental results showed that in the 305 cases of stones, calculi oxalate stones were found to account for 63%, uric acid stones 22%, calcium phosphate stones 8%, struvite 5%, and the stones with other compositions 2%. There were significant differences in the thermoluminescence spectra among the 4 types of urinary stones, which can provide an important basis for the clinic diagnosis of urinary stone types.
