[Extra-corporal shock wave lithotripsy using the HM3 Dornier lithotripter with a modified shock wave generator. Initial clinical reports of experiences].

We report on the clinical application of a modified shock-wave generator for the Dornier Lithotripter HM 3. Stone fragmentation, complication rate, and frequency of auxiliary measures were unchanged in comparison to the former generator. The new shock-wave generator led to markedly reduced patient discomfort during treatment, with the result that more than 50% of all ESWLs could be done with sedation only or without any medication.
