FIELD: medicine.

SUBSTANCE: invention refers to medicine, oncology, urology, radiology, methods of registration auto fluorescence of tissues for more efficient use of low-dose brachytherapy of localised forms of malignant tumors of the prostate gland. Implantation is carried out at ultrasound control of microcapsules with radionuclide I-125 by trans-perineal access in prostate tumor tissue by template with holes with a pitch of 5 mm. Previously at the beginning of operation through the holes of the template is introduced in prostate tissue a diagnostic catheter for registration of auto fluorescence. Determined amount of centers of auto fluorescence typical for tumor tissue, and their boundaries. According to this data is determined the radiation dose, number of microcapsules and nature of their distribution at implantation.

EFFECT: method allows more precise and specifically explore a whole volume of the body, exclude the possibility of passage of prostate parenchyma sections at its complex anatomical structure or considerable dimensions, as well as use the obtained value for target distribution of micro sources and calculation of necessary doses to avoid bringing excess radiation effect on the surrounding healthy tissues, reduce rate of developing early and late radiation complications.
