FIELD: medicine, in particular, oncology and urology, possible use for treatment of surface cancer of urinary bladder.
SUBSTANCE: in accordance to method, tumor is irradiated by laser with output power 0,5-2 Wt with wave length 662 nm and light energy of 300-600 J/cm2 during 10-30 minutes in presence of specified photosensitizer injected intravenously in volume of 0,8-1 mg/kg. Then a silicon vessel is inserted into urinary bladder with fibro-optical filament with cylindrical diffuser positioned therein. Vessel is filled with distilled water and laser irradiation of whole mucous tunic of urinary bladder by light energy at 30-40 J/cm2 is continued during 40-60 minutes.
EFFECT: possible decrease of frequency of relapses and collateral reactions.
