The authors modified the China-made extracorporeal shock wave lithotriptor (Dornier HM3) (ESWL), and successfully developed the first home-made non-immersed extracorporeal shock wave lithotriptor not necessitating anesthesia. From 8 September 1987 to 8 February 1988, the authors treated 250 patients with stones of the upper urinary tract with their ESWL device. Stones were completely fragmented in 194, partially in 44, and not disintegrated in 12 cases. The overall fragmentation rate of calculi was 95.2%. Followup from 1 to 6 months showed that 128 patients were cured, and 11 patients were markedly improved. This ESWL equipment works well, and can be used clinically in selected cases.
作者对国产体外冲击波碎石机（多尼尔HM3型）进行了改进，成功研制出第一台国产无需麻醉的非沉浸式体外冲击波碎石机。1987年9月8日至1988年2月8日，作者使用该体外冲击波碎石设备治疗了250例上尿路结石患者。结石完全粉碎的有194例，部分粉碎的有44例，未粉碎的有12例。结石的总粉碎率为95.2%。1至6个月的随访显示，128例患者治愈，11例患者明显好转。这种体外冲击波碎石设备运行良好，可用于部分临床病例。
