Abstract: Recently a new idea for the disintegration of urinary calculi based upon the large difference of the acoustic impedance inside urinary calculi was suggested. This large difference of acoustical impedance between the two main components of kidney stones, is confirmed in this paper for smooth laminated uric acid stones by two different experimental techniques measuring sound velocities: a surface contact and a submersion technique. Our measured values correlate well with the large differences of the earlier reported measured sound velocities. In general, the disintegration of a urinary stone can be described as follows: a urinary calculus is an inhomogeneous geometrical structure, and its structure plays an important role in the disintegration process.
