ABSTRACT In this investigation, ultrasonic parameters of kidney stones are measured, in vitro, using a double probe ultrasonic-through-transmission technique. Due to the complex chemical structure of these stones, a large variation in the values of the ultrasonic parameters is found. A correlation between ultrasonic properties and variation in pathology of the renal calculi is also discussed.
