Abstract
Achieving optimal results with extracorporeal shock wave lithotripsy is dependent both on technical factors related to lithotriptor design as well as careful attention to technique during the performance of lithotripsy. Recent research suggests that lithotriptor designs employing broad focal zones and lower pressures (as existed in the original lithotriptor, the Dornier HM3) provide the best balance between effective stone fragmentation and minimal tissue effects. Ensuring adequate coupling during lithotripsy is critical. Stone fragmentation can also be enhanced by slowing the shock wave delivery rate. No matter what lithotriptor design is being utilized, it is likely that ramping up gradually on the pressures in f2 will minimize tissue effects. In summary, both technology and technique are important to achieving optimal outcomes with extracorporeal shock wave lithotripsy.
