Authors : B. Shokouhi , K. Gasemi and E. Norizadeh

Abstract: The aim of this study was to perform the chemical analysis of stones to investigate the pattern of biochemical composition of stones and to determine epidemiological risk factors for stone formation in Ardabil province of Iran. Renal stones from 1268 patients were analyzed during 5 year period from March 2001-March 2006. These stones were sent to seven laboratories in 2 cities of Ardabil province for analysis from different clinics and hospitals. The stones were analyzed by semi-quantitative method (Saba kit). The powdered stones and standards both were analyzed for uric acid, cystine, oxalate, phosphate, ammonium, calcium and magnesium contents. Male to female ratio was 2.7:1. The stone frequency was very greater in adults as compared to children. Maximum number of stones was analyzed in summer months. Calcium oxalate stones were the commonest followed by uric acid and phosphate stones. Only 8 cystine stone was found in the series analyzed. From the study of epidemiological factors, it seems that the men are more prone to development of stones. A clear stone season seems to exist in the area corresponding to the summer months. The relative increased frequency of stones in the region indicates that nutritional, environmental and genetic factors play a role in the occurrence of stones. M/F ratio, male to female ratio; mm, millimeters; mg, milligrams
