PURPOSE Extracorporeal shock wave lithotripsy (ESWL) is well documented to exert destructive effect to renal cells and its mechanism is not clear. Autophagy is one of cell basic response for stressful conditions and it is important to determine cell's fate. The aim of this study is to elucidate the role of autophagy in the process of shock wave-induced renal cells injury. METHODS NRK-52E cell...

This study aimed to evaluate the clinical value of a novel ureter dilatation method during ureteroscopic pneumatic lithotripsy in patients with ureteral calculi and polyps. Clinical information of 86 patients with ureter calculi and polyps who underwent ureteroscopic pneumatic lithotripsy was reviewed. A cavity-distention machine was used in 44 cases to inject normal saline for keeping clear op...

A clinical study of the concept “wide-focus and low-pressure” extracorporal shock-wave lithotripsy (ESWL) was performed in a scientific cooperation between the Physical Institute of the University of Stuttgart and the Xixin Medical Instruments Co. Ltd. in Wuxian-Suzhou, China. In this cooperation, self-focusing electromagnetic shock-wave generator systems from the University of Stuttgart were i...

PURPOSE The use of shock waves in orthopedic diseases was reviewed with special regard to the clinical applications. MATERIALS AND METHODS Findings in the literature and results from our own studies were analyzed and summarized. RESULTS Extracorporeal shock waves induced osteoneogenesis in animal models with intact and fractured bones. Based on these findings shock waves were used for the t...

!i£l AJBS'JrRA CT Shock wave therapy is a relatively new treatment of foot and ankle pain. An acoustic sound wave similar to one used for lithotripsy can cause a hyperanalgesia effect reducing pain and can cause breakdown and neovascularization of c1u'onically damaged tissue. T1u'ee commercial sources are available for musculoskeletal applications. To date, the treatment seams to be effective f...

The temporal and spatial dynamics of cavitation bubble cloud growth and collapse in extracorporeal shock wave lithotripsy (ESWL) is studied experimentally. The first objective is obtaining reproducible cloud patterns experimentally and comparing them with FDTDcalculations. Second, we describe a method to modify the cavitation pattern by timing two consecutive pressure waves at variable delays. ...
