The recently developed equipment for extracorporeal piezoelectric lithotripsy (EPL) represents an improvement concerning the shock-wave-induced disintegration of urinary calculi. While the usual spark gap transmitter needs a focusing reflector, the piezoelectric lithotriptor is based on a self-focusing spherical bowl transmitter. The stone is detected exclusively by ultrasound. For this purpose, an integrated sector scanner is used as well as the high-energy sound transmitter itself. With the piezoelectrically generated high-energy sound pulses we have succeeded in completely disintegrating implanted stones in the renal pelvis of dogs without injuring the morphology or function of the exposed kidneys.
最近研发的体外压电碎石术（EPL）设备在冲击波致尿路结石崩解方面有所改进。普通的火花隙发射器需要一个聚焦反射器，而压电碎石器基于一个自聚焦球形碗状发射器。结石仅通过超声检测。为此，使用了一个集成扇形扫描仪以及高能声发射器本身。通过压电产生的高能声脉冲，我们成功地完全崩解了植入犬肾盂的结石，且未损伤暴露肾脏的形态或功能。
