The Swiss Lithoclast: A New Device for Intracorporeal Lithotripsy

Abstract

Modalities available for performing intracorporeal lithotripsy include ultrasonic, electrohydraulic and laser procedures. We present our experience with a new and unique technology for performing intracorporeal lithotripsy, namely the Swiss Lithoclast. This simple and inexpensive device uses compressed air to activate a solid probe in a manner similar to that of a jackhammer. We report the use of the Lithoclast in 31 cases, consisting of 6 renal calculi approached percutaneously, 17 ureteral calculi and 8 bladder calculi. The Lithoclast successfully fragmented 94% of the calculi. There were no intraoperative or long-term complications directly related to the use of this device. We have found the Swiss Lithoclast to be a safe, effective and inexpensive means of performing intracorporeal lithotripsy for calculi located throughout the urinary tract.
