Biological Effects Produced by High-Energy Shock Waves

2010
High-energy shock waves are known to produce a wide range of bioeffects associated with their clinical applications. In shock wave lithotripsy (SWL), which is the most successful application of shock waves in clinical medicine for noninvasive disintegration of kidney and upper urinary stones, transient hematuria, hematoma, and temporary deterioration ...

Effect of High-Energy Shock Waves on Bony Tissue

1989
The indication for extracorporeal shock-wave lithotripsy (ESWL) in the treatment of lumbar and distal ureteral stones is well established. Ureteral calculi projecting onto the bony structures of the pelvis are not amenable to ESWL. Treatment options would include shock-wave treatment with the patient in a prone position where shock waves would pass ...

Shock wave generated by high-energy electric spark discharge

Journal of Applied Physics, 2014
Shock wave generated by electric spark discharge was studied experimentally and the shock wave energy was evaluated in this paper. A pressure measurement system was established to study the pressure field of the electric spark discharge process. A series of electric spark discharge experiments were carried out and the energy of the electric spark used ...

Interferoemtric Measureemnts of the Shock-Waves Generated by the High Energy Laser

2018 IEEE International Conference on Plasma Science (ICOPS), 2018
The spatial and temporal evolution of the shock-waves generated by the high energy Nd:Glass laser at KAERI1 were simultaneously measured by Nomarski interferometer and ORVIS. The Nd:Glass laser with pulse energy ~20 J and pulse duration 8 nsec was irradiated onto an Al sample in the air to generate laser-plasma and shock-waves.

Effects of High Energy Shock Wave Exposure on Renal Function during Extracorporeal Shock Wave Lithotripsy for Kidney Stones

European Urology, 1990
In order to study the effects of high energy shock wave exposure on the kidney in extracorporeal shock wave lithotripsy (ESWL) using Dornier HM3, renal hemodynamics and renal function before and after ESWL were analyzed by 99mTc-DTPA renoscintigraphy.

Reduction of high-energy shock-wave-induced renal tubular injury by selenium

Urological Research, 1999
In shock-wave-induced renal injury cavitation-generated free radicals play an important role. Using an in vitro model with Madin-Darby canine kidney (MDCK) cells, we investigated the influence of selenium, a free radical scavenger, in shock-wave-induced tubular cell injury. Suspensions of MDCK cells (33 x 10(6) cells/ml) were placed in small containers

Histopathologic and Ultrastructural Correlates of Tumor Growth Suppression by High Energy Shock Waves

Journal of Urology, 1987
High energy shock waves (HESW) are cytotoxic to tumor cells as determined by vital staining and impaired ability of viable cells to form colonies in a clonogenic assay. In addition, direct exposure of tumor nodules to HESW results in suppression of tumor growth rate.

Effect of high-energy extracorporeal shock waves on the immature epiphysis in a rabbit model

Archives of Orthopaedic and Trauma Surgery, 2007
We investigated the effect of high-energy extracorporeal shock wave (ESW) on immature tibial epiphysis in a rabbit model.Twenty New Zealand white immature rabbit were used in this study. Animals were divided into two groups and they received 14 kW, 0.6 mJ/mm(2), 1,500 or 3,000 shots for three times with an interval of 7 days.

Effects of Lithotripter-Generated High Energy Shock Waves on Mammalian Cells in Vitro

Journal of Urology, 1992
The effects of high energy shock waves on an established human prostatic carcinoma cell line (PC-3) were investigated. HESW were administered to PC-3 cell suspensions using an electrohydraulic lithotripter (Dornier HM3). Experimental variables included the number of shocks to which the cells were exposed, spark generator potential, and the position of ...

The Effect of High Energy Shock Waves Focused on Cortical Bone: An in Vitro Study

Journal of Surgical Research, 1993
Extracorporeal shock wave lithotripsy has become an accepted alternative for the management of nephrolithiasis and cholelithiasis. Direct impact of shock waves cause tear and shear forces at transition sites between tissues with divergent acoustic impedances leading to stone fragmentation.
