Extracorporeal Shock Wave Gallstone Lithotripsy
We have investigated 30 cases of gallbladder stone patients treated by extracorporeal microexplosive biliary lithotripsy. The lithotriptor used for tratment is a Yachyoda SZ-5000, using as the energy source microexplosive pellets (AgN3).The stone-free rate was 12/30 (40%). Especially type Ia and Ib stones (ultrasonographic classification) were treated most effectively. The stone-free rate for types Ia and Ib was 4/6 (67%) and 5/5 (100%), while the side-effects and complications were mild. Extracorporeal microexplosive biliary lithotripsy was very safe and effective in patients whose ultrasonographic classification of the gallstone was type Ia or Ib.
