ABSTRACT
The paper reports an experimental technique and the results obtained in the study of cavitation arising in focusing the shock wave of electrodynamic lithotriptor. The aim of the above study was to specify mechanisms of soft tissue lesions during destruction of nephroliths with lithotriptor impulses. Cavitation regions were found along the axis of the generator focusing system and at its outgoing sites as a result of the boundary expansion wave. This phenomenon by the body margin is attributed to transformation of a positive pressure impulse into the tension impulse. As the shock wave pressure impulse is much more significant than the pressure impulse of the boundary expansion wave it is most probable that cavitation-induced lesions appear at the site of the wave exit from the body.
