A cumulative shear mechanism for tissue damage initiation in shock-wave lithotripsy.
Evidence suggests that inertial cavitation plays an important role in the renal injury incurred during shock-wave lithotripsy. However, it is unclear how tissue damage is initiated, and significant injury typically occurs only after a sufficient dose of shock waves. Although it has been suggested that shock-induced shearing might initiate injury, estimates indicate that individual shocks do not...
متن کاملKidney damage in extracorporeal shock wave lithotripsy: a numerical approach for different shock profiles.
In shock-wave lithotripsy--a medical procedure to fragment kidney stones--the patient is subjected to hypersonic waves focused at the kidney stone. Although this procedure is widely applied, the physics behind this medical treatment, in particular the question of how the injuries to the surrounding kidney tissue arise, is still under investigation. To contribute to the solution of this problem,...
متن کامل[Extracorporeal shock-wave lithotripsy].
Concrement lithotripsy in the kidney and ureter using extracorporeal shock waves (ESWL) was performed with the aid of a 2nd-generation lithotriptor--Lithostar Siemens. Over a period of 11 months ESWL was applied in 526 patients aged 7 to 80 years, 10 of these were children. 19 patients had bilateral lithiasis so that the treatment was applied to a total of 545 renoureteral units and 698 concrem...
متن کاملShock wave induced damage in kidney tissue
In a common medical procedure known as shock-wave lithotripsy hypersonic waves are generated and focused at the kidney stone. These shock waves are thought to fragment the stone but also lead to injuries of the kidney tissue. To predict and estimate this damage we develop here a mechanical model for the response of soft tissue to the exposure of shock waves. The material model combines shear in...
متن کاملExtra-corporeal shock wave lithotripsy.
Extra-corporeal shock wave lithotripsy (ESWL) has proved to be a revolutionary advance in the treatment of renal stone disease. It, itself, is non-invasive but may necessitate or be used as an adjunct to more invasive auxiliary procedures. The basic principles of lithotripsy, the clinical experience thus far and probable future applications are discussed.
