[Mobile extracorporeal piezoelectric lithotripsy (EPL)--suitable for which stones?]

We report our experience with the first 42 patients treated with extracorporeal piezoelectric shock wave lithotripsy (mobile Wolf Piezolith 2300, being once a month to our disposition). In our opinion, this fact influences the indication for the treatment with this lithotriptor; large stones should be treated first either by percutaneous litholapaxy or ESWL, with a Dornier-Lithotriptor.
