The technical innovation of a low pressure generator with a standard ellipsoid installed into the Dornier HM3 lithotriptor leads to a decrease in pressure at the second focus by 30 per cent. The preliminary experience with 273 patients treated at 2 centers is presented. The success rate in terms of stone disintegration was similar compared to the old generator (96 versus 97 per cent). However, the rate of secondary treatments increased from 8 to 15.5 per cent, respectively. Owing to the lower peak pressures at the second focus, an additional 700 impulses per session were necessary. The method of anesthesia was changed to a combination of an anxiolytic and analgesic drug in the majority of the patients. Treatment was judged as free of pain or with easily tolerable pain in 93 and 88 per cent of the patients, respectively.
将标准椭圆体安装到多尼尔HM3碎石机中，这种低压发生器的技术创新使第二焦点处的压力降低了30%。本文介绍了在两个中心对273例患者进行治疗的初步经验。结石粉碎方面的成功率与旧的发生器相似（分别为96%和97%）。然而，二次治疗率分别从8%增加到了15.5%。由于第二焦点处的峰值压力较低，每次治疗需要额外增加700次脉冲。大多数患者的麻醉方法改为使用抗焦虑药和镇痛药的组合。分别有93%和88%的患者认为治疗过程无痛或疼痛易于耐受。
