    Abstract:
    BACKGROUND: In recent years the role of trace elements in lithogenesis has received steadily increasing attention. OBJECTIVES: This study was aimed to attempt to find the correlations between the chemical content of the stones and the concentration of chosen elements in the urine and hair of stone formers. MATERIAL AND METHODS: The proposal for the study was approved by the local ethics committee. Specimens were taken from 219 consecutive stone-formers. The content of the stone was evaluated using atomic absorption spectrometry, spectrophotometry, and colorimetric methods. An analysis of 29 elements in hair and 21 elements in urine was performed using inductively coupled plasma-atomic emission spectrometry. RESULTS: Only a few correlations between the composition of stones and the distribution of elements in urine and in hair were found. All were considered incidental. CONCLUSIONS: The data obtained did not allow for the creation of a proper and practical algorithm to predict stone chemical composition based on hair and urine analysis.
