DIAGNOSTIC ACCURACY OF ULTRASOUND IN DETECTING GALLBLADDER STONES: A CLINICAL STUDY

Abstract

Background: Gallbladder stones (cholelithiasis) are a common gastrointestinal condition, often diagnosed using non-invasive imaging modalities such as ultrasound. This study evaluates the diagnostic accuracy of ultrasound in detecting gallbladder stones. Objectives: To determine the diagnostic accuracy of ultrasound for gallbladder stones and analyze associated demographic and risk factors. Methods: A cross-sectional study was conducted on 28 patients clinically suspected of having gallbladder stones. Ultrasound findings were compared with intraoperative or radiologic confirmatory diagnoses. Demographic and risk factors were recorded and analyzed. Results: Out of 28 patients, ultrasound correctly diagnosed gallbladder stones in 25 cases, yielding a sensitivity of 92.6% and specificity of 100%. Most patients were females aged between 30–50 years. Obesity, female sex, and a family history of gallstones were the most common risk factors. Conclusion: Ultrasound is a highly sensitive and specific, non-invasive, and cost-effective modality for detecting gallbladder stones.
