Abstract

This paper presents a study of the role played by cavitation role in the disintegration of urinary calculi generated by a modified extracorporeal shock wave lithotripsy (ESWL) system. The ElectroMagnetic Acoustic Source of a Lithostar lithotripter initiated the incident shock waves into the water, and the ultrasound transducer fixed into the system played an important role by enhancing the cavitation effects of the bubbles in the Calcium-silicate target fragmentation..
