... between 200 and 400 bar (20-40 MPa) where lithotripsy can be performed successfully and the tissue can be protected. By calculation of isobar zones the pressure distribution of different lithotripters can be compared quantitatively. From this it becomes evident that the dynamic range of the Lithostar...

...C. Pertusa; A. Albisu; M. Acha; M. Blasco; R. Llarena; J.G. Tanago The Alexandrite laser system has proven to be an effective and safe method of ureteral lithotripsy. Some authors have recently reported the risk of intersper- sion of fiber splinters into tissue during lithotripsy, when short pulses...

...G. Köhler; U. Schätzle; B. Granz An improved shock wave source is required for the extended application of extracorporeal lithotripsy in proven and anticipated novel fields of therapy. Fundamental research was performed in the domains: disintegration efficiency; hydrophone stability; absolute...

...G. Vallancien; N. Defourmestraux; J.P. Léo; L. Cohen; J. Puissan; B. Veillon; J.M. Brisset 1,200 extracorporeal lithotripsies have been performed in 816 patients. 58% of the stones had a diameter of 3-10 mm, 41% measured between 11 and 20 mm and 1% were larger than 20 mm. The patients were all...

...M.C. Cheung; F. Lee; S.K.H. Yip; P.C.
