title: [Lithotripsy of biliary calculi: evaluation of ultrasonography as a method to guide treatment by extracorporeal shock waves].
abstract: Extracorporeal shock-wave lithotripsy is a procedure recently introduced to treat gallstone disease. According to the literature, 15% to 25% of symptomatic persons will be candidates for this procedure if it proves effective. Currently, sonography is one of the best methods for monitoring the performance of lithotripsy. The authors have confirmed this. They have designed an in-vitro model which allows comparison between what is actually happening during gallstone lithotripsy and what is being seen by real-time sonography. The sonographic characteristics of the different phases of gallstone lithotripsy are presented.
