Notes:
Urolithiasis is a disease that has been studied for many years, and the ethiopathogenesis of stone formation is not well understood. It is therefore important to fully recognize both the stone's chemical structure and composition. The structural composition of renal stones was determined by Fourier transform infrared spectroscopy and Fourier transform Raman spectroscopy. The elemental composition was determined by means of proton-induced X-ray emission, and the lead concentration was confirmed using atomic emission spectroscopy. Because of varying calculi composition, it was convenient to divide the stones into six groups: magnesium ammonium phosphate hexahydrate (struvite), calcium phosphate (apatite), mixed phosphates and oxalates, calcium oxalate mono- and dihydrate (whewellite and wedellite), mixed oxalates and uric acid, and uric acid. Trace elements interact with the body's organs and thus play a significant role in the living processes. It is important to establish concentration levels in analyzed materials. Such information can help in the diagnosis and evaluation of the risk of stone formation. Therefore, the concentration of trace elements in the samples has been determined. The correlation between lead concentration and structural composition and the correlation between lead concentration and environmental influence were found. The results obtained were statistically analyzed. © 1997 John Wiley & Sons, Inc. Biospectroscopy 3: 403-407, 1997
