BACKGROUND: Our objective is to analyze ultrasonographic and clinical variables such as the presence or absence of bile sludge, thickness of the gallbladder wall, transverse measurement of the gallbladder, age, parity, and presence or absence of diabetes mellitus and to determine the prevalence of asymptomatic gallstones in female patients submitted to ultrasonographic examination. METHODS: A prospective study was conducted on 265 female patients attended at the Ultrasonographic and Medical Updating School of Ribeirão Preto during the period from January to September 2001. RESULTS: There was a statistically significant difference in gallstones and gallbladder wall thickness, bile sludge, transverse gallbladder diameter, age range, parity, from 4.1% among nulliparous women to 39.1% in multiparous women and women with diabetes. The prevalence of gallstones in asymptomatic patients was 14.7%. CONCLUSION: The asymptomatic gallstones in women were mainly related to age and parity. The presence of galbladder wall thickness and bile sludge were the most frequent ultrasographic findings.
