Infrared Spectral Studies of Urinary Stones Resected from Urinary Bladder

The urinary stone resected from urinary bladder of a patient hailing from Kollam district of Kerala, India is characterized by using analytical techniques like powder XRD, EDAX and FTIR spectroscopy. The EDAX spectrum of the sample shows the presence of carbon, nitrogen and oxygen in the sample under investigation. Most of the XRD peaks can be indexed to that of uric acid with monoclinic structure. The most intense band in the IR spectrum is observed at 1122 cm−1 and is due to C–C stretching vibrations. The XRD and FTIR investigations suggest that the major constituent of the present sample is uric acid.
