title: [Prevalence of gallbladder lithiasis in a Uruguayan population].
abstract: Ultrasound examinations were carried out in 693 volunteers from the health care personnel of the Hospital de Clinicas of Montevideo, with the aim of studying the prevalence of gallbladder gallstones in Uruguay, the proportion of symptomatic and asymptomatic people and its association to some definite risk factors. The prevalence found was 10.4%, which, according to the sample's size, is representative of the general population with a confidence of 99%. Sixty five per cent of gallstones carriers were asymptomatic. A statistically significant association with the following factors was found: people between 31 and 50 years old, slight obesity, and, for women, to have children. A marked tendency with the following factors was found, though it was not statistically significant: female sex, and a familiar history of mother carrying gallstones. Considering all these factors as a whole, the probability of having gallstones reached 19%. Results are discussed and compared with those of foreign publications. It is concluded that uruguayan people with more possibilities of having gallstones are: women between 31 and 50 years old, obese, with children, and whose mother has or had the same disease.
