Endoscopic Neodymium-YAG laser application for destroying bladder tumors.
302 bladder tumors to a size of a thumb tip were treated with a Nd: YAG laser. 196 large bladder tumors were removed by transurethral resection combined with laser irradiation 1 week later. In all cases tumors were classified as pTA to pT3a, No, Mo tumors. 8 weeks after treatment we found local recurrences in 9% using the rigid laser endoscopes. On the contrary, the local recurrence was 2.1% using laser endoscope with modified Albarran insert. In proven cases the Nd:YAG laser application is an effective and careful procedure to destroy bladder tumors.
