ABSTRACT
The sensitivity and specificity of ultrasound investigation (USI) and x-ray methods of indirect and direct contrast studies of the biliary system in the diagnosis of cholecysto- and choledocholithiasis were compared by a blind control method. USI was shown to be superior over all x-ray contrast methods in the diagnosis of cholecystolithiasis. The diagnosis of choledocholithiasis usually requires the use of x-ray methods among which preference should be given to endoscopic retrograde cholangiography as the most informative method permitting simultaneous intervention on the major duodenal papilla.
