title: Biliary Lithiasis: Prevalence and Ultrasound Profile in a Service Hospital.
abstract: Real time gray scale ultrasonography of upper abdomen was carried out in 1237 cases for varied indications. Overall prevalence of biliary lithiasis was 11.56% with female to male ratio of 4:1. Fifty years and below, female to male ratio was 6.5:1. 88.8% cases of biliary lithiasis were 60 years and below. Gall bladder dyspepsia (61.5%) and right upper quadrant pain (41%) were the main presenting features of biliary lithiasis. 26 patients (18%) presented with acute abdomen. Asymptomatic gallstones were found in 25 (17.5%) cases. Solitary calculus was less common than multiple calculi with a ratio of 1:4. Amongst cases of multiple calculi the small sized (2-4 mm) variety was the maximum (49%) followed by medium sized (5-10mm) and large sized (>10mm) calculi respectively.
