Analysis of constituents of 426 urinary stone samples in Shaanxi province with infrared spectroscopy

Objective To study the constituents of urinary stones in Shaanxi province in recent years and to provide prevention and treatment of urinary stones. Methods 426 urinary stone samples colleted in Shaanxi province were analyzed with LIIR Automatic Analysis System of Infrared Spectroscopy （Tianjin）. Results 72.3% of the stones were mixed. The components of urinary stones were calcium oxalate monohydrate （71,83%）, carbonate apatite （63.85 %）, calcium oxalate dehydrate （42.26%）, uric acid dehydrate （11.03%）, ammonium （3.76%）, and ammoniomagensium phosphate （3.29%）. Conclusions The constituents of urinary stones in Shaanxi province are calcium oxalate, carbonate apatite and uric acid.
