This paper reports how laboratory experiments and hydrocode simulations (of cavitation
and shock wave propagation) have been used to generate a clinical device which can deliver real
benefit to patients with kidney stones. Currently X-ray or ultrasound B-scan imaging are used to
locate the stone and to check that it remains targeted at the focus of the lithotripter during
treatment. Neither imaging method is particularly effective in allowing the efficacy of treatment
to be judged during the treatment session. In this study, laboratory experiment and
Computational Fluid Dynamics simulations of the complex interactions between the shock wave,
the stone, and the human tissue, have been used to develop a new clinical device. This device,
which has been tested in clinical trials, exploits the passive acoustic emissions generated by these
interactions, to identify whether the stone remains in the focus, and to what extent the treatment
has been successful.
