[A new laser endoscope for irradiation of bladder tumors].

A new endoscopic laser tool is presented consisting of a urethrocystoscope with Albarran-tray. Because of the flexibility of the new guide light fibres it is possible to irradiate any spot of the bladder wall, the bladder neck and the fascia prostatae. Advantages are apart from the flexibility--the simplifying of the equipment, the good working conditions under water and the higher efficacy using the same power output as the usual laser endoscopes.
