Epidemiological Study of Urolithiasis with special reference to its chemical nature. To find out the quality of urinary stone. The collected stones were sent to the Department of Biochemistry, K.M.C.H, Katihar. Qualitative biochemical analysis were performed to know the composition of the stones by H. Varley method. It was a prospective study. A total of 23 patients had been studied. The study period is of 1 year duration of which male – 14, female – 9 all were collected after intervention. Age group was from 8 years to 70 years. 73.91% of the case studied was renal calculi. 94.11 % of all the renal calculi was unilateral. 21.73% of all the urolith was  ureteric calculi and bladder stone was 8.69%.
