[Value of ultrasonography for the diagnosis of cholelithiasis in light of surgical verification].

Up to the age of ultrasonography the cholelithiasis diagnostics has been based on the radiologic examination that is on the peroral cholecystography introduced by Graham and Cole in 1924 as well as on the intravenous cholangiography performed for first time by Langecker and Harwat in 1952. During last years the cholelithiasis diagnostics is more and more frequently based on the ultrasonographic examination. The purpose of this study was in evaluation of ultrasonography in detection of cholelithiasis. The diversity of ultrasonographic images according to the cholelithiasis type and the accompanying alterations in the wall and surrounding area of the gallbladder has been taken into account. The USG diagnostic value and that of routine radiologic methods in diagnosis of cholelithiasis has been additionally compared.
