title: [Conventional ultrasound in the diagnosis of bile duct calculi].
abstract: Transabdominal ultrasound (US) is one of the most useful methods in the diagnosis of biliary stones.
  
  
  OBJECTIVE
  To appreciate the value of US in the diagnosis of bile duct stones.
  
  
  METHODS
  989 patients, explored in the Institute of Gastroenterology and Hepatology Iaşi by US compared with ERCP, MRCP, operative diagnosis and the final diagnostic.
  
  
  RESULTS
  The sensitivity of US in the detection of bile duct stones was 78.39% and specificity was 72.22% in the first group of 650 patients, and bile duct stones were identified in 139 cases of 339 of the second group where US could not identify the cause of bile duct dilatations.
  
  
  CONCLUSIONS
  The results were comparable with the most recent studies in the literature.
  
  
  CONCLUSIONS
  US is an efficient method for the diagnosis of bile duct stones in many cases and remains the first step in the diagnosis.
