“…They were realized in the "Institut der Gesellschaft für Strahlen-und Um- Later pilot studies were started by Miissiggang (9, 10) using neodymium-YAG laser and carbon dioxide-laser in kidney and spleen surgery. In animal experiments in 1973 Breitwieser et al (1) made partial kidney resections using the carbon dioxidelaser. In this study, they could not report any advantage to the use of the carbon dioxide laser.…”

For the first time cystoscopic argon and neodymium-YAG laser irradiation of the bladder wall using a flexible quartz fiber light guide (as described by Nath) was studied morphologically and histologically. It was seen that it is possible to control the depth of tissue removal without the risk of perforation of the bladder wall. Therefore endoscopic surgery of bladder tumors by laser radiation seems to be possible. Hydronephrosis could not be observed even after direct laser irradiation of the orifices.

“…The endoscopic applications of first argon and later Nd: YAG (neodium:ytrium aluminium garnet) lasers were reported by Bociates in 1973 (1). Applications oflasers in medicine have since expanded to include laser lithotripsy, laser treatment of benign prostatic hypertrophy, photodynamic therapy and laser destruction of bladder tumors (2)(3)(4)(5)(6)(7).…”

In this work, morphological processing is applied to study a bubble, which is crucial factor in laser-induced shock-wave lithotripsy. Erosion, dilation and subtraction are applied for edge detection of a bubble Hence the position and the shape is measured. The image of the bubble is extracted from the actual image of the stone (shadowgram). The image is obtained by fast photography using an N-Dye laser for illumination. A Ho: Yag laser is used for fragmentation ofthe stone. Using a time delay, an oscilloscope and a computer, two laser pulses are synchronized. A microscope and a Kodak-camera are used to photograph the stone and the phenomena around.

Development of a carbon dioxide laser cystoscope

et al. 1980

CO2 laser lesions were created at varying power densities on the exteriorized canine bladders. A 50-watt carbon dioxide continuous laser coupled to a Zeiss surgical microscope was used. A schematic power curve was developed indexing depth of bladder penetration by the laser against laser energy output. Once the optimal power settings for the carbon dioxide laser were established, vertical heat transmission, hemostasis, and healing were studied. A prototype carbon dioxide laser cystoscope was then constructed that allowed endoscopic delivery of the CO2 laser beam into the intact canine bladder. The beam was focussed by a germanium lens and directed out the end of the endoscope, using a movable mirror. Eight dogs were then endoscopically studied in vivo.
