MODIFICATION OF DORNIER HM-4 LITHOTRIPTOR FOR PEDIATRIC EXTRACORPOREAL SHOCKWAVE LITHOTRIPSY

Extracorporeal shockwave lithotripsy has enjoyed increasing acceptance and utility in pediatric urology. The Dornier HM-4 lithotriptor has h ad good results in adults, but the gantry design does not allow smalle r children to be treated. We have employed a specially designed yet si mple ''spacer'' to allow smaller children to be treated safely. The de vice may also have application in older patients with deformities who could not be treated in the past.
