The analyses of compositions of urinary stones can provide significant reference to the treatment and prevention of recurrence of urolithiasis. In the present paper, the application and research progress of composition analyses of various urinary stones such as calcium oxalates, phosphates, uric acid, urates, cystine etc. by means of modern instruments are summarized. These techniques include Raman spectroscopy, thermogravimetry analysis/differential thermal analysis (TGA/DTA), nuclear magnetic resonance (NMR), high-performance liquid chromatography (HPLC), Fourier infrared (FTIR) spectroscopy, etc.

In the present study, FT-IR, XRD, TGA-DTA spectral methods have been used to investigate the chemical compositions of urinary calculi. Multi-components of urinary calculi such as calcium oxalate, hydroxyl apatite, struvite and uric acid have been studied. The chemical compounds are identified by FT-IR spectroscopic technique. The mineral identification was confirmed by powder X-ray diffraction patterns as compared with JCPDS reported values. Thermal analysis techniques are considered the best techniques for the characterization and detection of endothermic and exothermic behaviors of the urinary stones. The percentages of each hydrate (COM and COD) are present together, in the presences of MAPH or UA. Finally, the present study suggests that the Urolithiasis is significant health problem in children, and is very common in some parts of the world, especially in India. So that present study is so useful and helpful to the scientific community for identification of latest human health problems and their remedies using spectroscopic techniques.
