Summaryummary A study dealing with urinary lithiasis frequency in San Luis city, Argentina, applying infrared spectroscopy is reported for the first time. The infrared spectra of 169 urinary stones provided by public and private sanitary centers were analyzed. The most frequent chemical components found were calcium oxalate monohydrate, urates, calcium phosphate, magnesium ammonium phosphate hexahydrate and mixed compositions. Quantitative data analysis, performed by descriptive sta- all the cases, as well as its distribution according to the corresponding age and sex. Calcium oxalate monohydrate and urates were more frequently found in men than in women ranging between 21–60 and between 41–70 years old, respectively. The inverse ratio is determined for calcium or magnesium phosphates, women being the most affected. Stones with mixed composition showed the same incidence in women and men. all the cases, as well as its distribution according to the corresponding age and sex.
