Paper Abstract

Vhe paper reports that 149 bladder tumors in 40 patients were treated by gold vapor laser photodynamic therapy in the period from June 1989 to August 1991. The light fiber output power of gold vapor laser is more than 2 W, that spread through a spherical diffuse light leading fiber. Focusing the irradiation on the tumor and the whole bladder the power density was 70.77 mw/cm2 to approximately 509.55 mw/cm2. After a follow-up of 4 to 24 months we found the following results: cured 28 cases (70%); good effect in 11 cases (27.5%); improved 1 case (2.5%); and regenerated 4 (10%).
