Hardness Testing of Urinary Calculi
With the advent of electrohydraulic and extracorporeal shock wave lithotripsy, it is important to document the mechanical properties of urinary calculi. Since the success of both techniques is affected by the compressive and tensile strength of the calculus, we have compared the hardness of a variety of urinary calculi. This information may be important in understanding the limitations of these new techniques.
