[Endoscopic laser therapy of bladder tumors in man]

15 patients with papillary bladder tumors were radiated with a Neodym-YAG laser beam since summer 1976. The seize of the tumors ranged from 5 to 10 mm in diameter. Neither complications nor tumor recurrency in the former tumor area could be observed. A final statement about the value of laser radiation in malignant tumors is not yet possible because of the small number of patients and the short control period. However, our preliminary experiences might be a beginning of a successful improvement of bladder tumor therapy by use of endoscopic laser radiation.
