摘要：
The goal of this study was to describe: the design and performance of dual-phase reflectors to be used in electrohydraulic lithotripters in order to increase efficiency during extracorporeal shock wave lithotripsy (ESWL). These reflectors generate two phase-inverted pulses, instead of only one positive peak, followed by a trough, as in conventional systems. Pressure measurements and stone fragmentation efficiency of two novel reflectors were compared to that of a conventional reflector. One of the new reflectors was more efficient in breaking up kidney-stone models than the conventional ellipsoidal reflector.
