Acute and Follow-up Results of Piezoelectric Gallbladder Stone Lithotripsy

Seventy-five patients fulfilled the standard selection criteria for treatment of gallstones with piezoelectric lithotripsy. The ages of the patients ranged from 23 years to 73 years. Successful fragmentation could be observed in 74 patients (99%). The mean maximum fragment diameter after the first treatment session was 3.9 mm, measured 12 to 16 hours after lithotripsy.
