Abstract

The renal calculi in the kidney cause discomfort to the patient, and should be removed in time. These days, these stones are removed by non-invasive techniques like extracorporeal shock wave lithotripsy. The actual mechanisms of disintegration are, however, not fully known, though cavitation is an accepted phenomenon. As the renal calculi are piezo-electric in nature, a voltage potential is found to occur in these stones, which is studied here as one of the new phenomena of the disintegration
