[A new theoretical and experimental validation of the treatment and prevention of cholelithiasis]

Approaches are proposed, new in principle, toward breaking biliary calculi into pieces, as well as toward prophylaxis of cholelithiasis. Exposure of the concrements to ultrasound with varying resonance frequency in a contact medium containing litholytic substances permits bringing about their reduction to fragments being safe for their evacuation from the biliary system. Prevention of cholelithiasis involves identification of precalculous period and exposure of the gallbladder region to vibration along with adopting conventional therapy.
