Since the May 1988, when the extracorporeal shock wave lithotripsy was initiated in Hungary, the indication has gradually enlarged. Elaborated methods for making better the radiological perceptibility, focusing and targeting of stones, and auxiliary endoscopic procedures have led to spread of indication. 80-85% of kidney- and ureteral stones needed intervention can be treated successfully by ESWL method.
