Electrohydraulic lithotripsy (EHL) is a common treatment modality for kidney and ureteral stones. During EHL, a spark discharge at the tip of a small probe introduced endoscopically produces a vapor plasma and subsequently a cavitation bubble near the stone surface. Through high-speed photography and acoustic measurement, the transient cavitation bubble oscillation and associated shock wave generation during EHL were successfully characterized.
