Abstract
Since the introduction of ESWL by Chaussy in 1980, the therapeutic strategy for urolithiasis has completely changed. Dr. Christain Chaussy of the University of Munich was the first to pulverize renal calculi in humans using a new concept termed “extracorporeal shock wave lithotripsy. Using this technology, he determined that patients could have renal or ureteral stones removed without the need of an incision or skin puncture. Due to its noninvasiveness, the concept quickly gained widespread acceptance and became the treatment of choice for the vast majority of urinary stones. The first lithotripter model (Dornier HM-1) was soon replaced by the HM-2 in 1982, and the HM-3 in 1984. The HM-3 was first used in the United states on February 23, 1984 at Methodist Hospital in Indianapolis(Tiede et al., 2003).
