In the case of extracorporeal shock wave lithotripsy (ESWL), a shock wave-bubble interaction inevitably occurs near the focusing point of stones, resulting in stone fragmentation and subsequent tissue damage. Because shock wave-bubble interactions are high-speed phenomena occurring in tissue consisting of various media with different acoustic impedance values, numerical analysis is an effective...

Shock waves as high energy acoustic are generated from underwater explosion with voltage condition in shockwave generator. The physical characteristics of a rapid positive peak pressure and negative that propagates rapidly through the body tissue. wave was primarily used to treat lithotripsy (kidney stone) by outside technique (called extracorporeal lithotripsy: ESWL). application shock has bee...

among 2379 patients with upper urinary tract stones who underwent eswl (extracorporeal shock wave lithotripsy) at sina hospitál using the siemens lithostar, 638 developed stone street (steinstrasse). of these, 516 (81%) passed all of the stone fragments spontaneously and no treatment was required, 90 cases (14%) had more eswl sessions to complete the treatment, and 30 (4.7%) required further in...
