Necromancing the stones.
Since its introduction 15 years ago extracorporeal shockwave lithotripsy (ESWL) has become a standard treatment for urinary stones. The author comments on the results of Adrian R. Levy and Maurice McGregor's study of the use of ESWL for urinary stones in Quebec (see pages 1729 to 1736 of this issue). The rapid increase in the use of ESWL that occurred in the first 2 years of the study points to the fact that the application of a new technology is often quickly expanded before thorough assessments of effectiveness and safety have been carried out. New technologies also lead to shifts in cost distribution that must be considered in cost analyses. The author argues that continuing research is needed to document the dissemination of new technologies and points to methodologic concerns that should be addressed to make such research as fruitful as possible.
