The experimentr eportedh ere was designed to find the causef or dissolvingth e urinary stones rapidly in EDTA solution by relatively low power ultrasonic irradiation without direct disintegration of the stone and systemice ffect of heating. In this experiment it has become clear that the irradiation with ultrasonic wave accelerated the dissolution of stones. The quantitative experimental studies using spherically shaped gypsum as model sample, moreover, have revealed that the ultrasonic irradiation increased the cheical dissolution rates of the model stone by10to30times. It may be probable that the increase in dissolution rate is ascribed to the following facts; the effects due to the microstream generated by the vibration of bubble associated with the ultrasonic irradiation and the effects due to the dance of the stone in EDTA solution by an intermittent straight flow generated by the ultrasonic wave pulse.
