Urinary stone disease causes discomfort, pain and occasional renal failure. Urinary stones are hard solid pellets, and are found in the urinary tract (kidney, ureter and bladder). Factors contributing to increased risk of urinary stones include family history, some disease conditions like Crohn's disease, urinary tract infections, renal tubular acidosis, hyperparathyroidism, medullary sponge kidney, and Dent's disease. Infrared spectroscopy using Fourier Transformation (FTIR) carried out in the department of Biophysics,  provides qualitative as well as a semi-quantitative analysis of the stone composition. Knowledge of chemical composition of stones may be of great importance both as a guide for planning the policy of medical management and also for understanding the physicochemical principles underlying calcul/stonei formation. This may help to initiate preventive
