Single pulse energy was 50 to 120mJ with a repetition rate of 20Hz. Urothelium and kidney parenchyma were irradiated in seven pigs. Tissue samples were examined histologically and electron-microscopically directly, two, four, eight and 12 days after irradiation. No macroscopic lesion could be found. Maximum energy caused a small ‘rupture cone’ of 40µm. depth. No thermic effects or necrosis resulted, so that no harm is to be expected with unintentional irradiation during laser stone disintegration. © 1988 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByHAUPT G and HAUPT A (2018) In Vitro Comparison of 4 Ultrasound Lithotripsy DevicesJournal of Urology, VOL. 170, NO. 5, (1731-1733), Online publication date: 1-Nov-2003.Schulze H, Haupt G, Piergiovanni M, Wisard M, Niederhausern W and Senge T (2018) The Swiss Lithoclast: A New Device for Endoscopic Stone DisintegrationJournal of Urology, VOL. 149, NO. 1, (15-18), Online publication date: 1-Jan-1993.
