Age range of patients in study group was 10-75 years with mean age of 33.6±7.5 years. Renal stones were collected from these cases and sent for chemical examination. Means, standard deviation and frequencies were calculated for qualitative data like age, gender and type of stone. Results: Total 1100 cases were studied including 64.8% male and 35.2% female cases. Prevalence of renal stone was higher among men than women wih male to female ratio of 1.8:1. Prevalence was higher in age group of 20-50 years among men and 30-40 years among women.
