The effect of focus size and intensity on stone fragmentation in SWL on a piezoelectric lithotripter

ConclusionsA smaller focus size, as well as a higher peak pressure results in a more effective stone fragmentation. However, these results need to be confirmed in an in vivo setting with multiple parameters interfering the efficacy, like BMI, respiration or stone migration.
