Urolithiasis is an important economic disease in food animal. This research was carried out on 500 slaughtered cows in the city of Shahrekord for determining frequency and relative frequency of nephrolithiasis. Results indicated that prevalence of nephrolithiasis was equal to 6% and in 80% of cases, nephroliths were found in left kidney (maybe due to decrease urine flow in suspended left kidney).
