A study of the frequency of vasicular lithiasis in an apparently sound sector of the population was conducted. It was found a frequency of affection of 6.2%. The predominance of the white race over the black one was just 1.8:1. This affection is much more common in the females than in the males (proportion 9:1), and among individuals over 40 (60%), who are overweight or obese (85%). It may be completely asymptomatic in 50% of the cases.
