METHOD FOR ENDOSCOPIC TREATMENT OF NON-MUSCLE INVASIVE BLADDER CANCER Russian patent published in 2015 - IPC A61B17/00 A61N5/67 

FIELD: medicine.

SUBSTANCE: transurethral bladder resection enables the exposure of tumour bed tissues to pulse laser light of wave length 970 nm and emitting power from 10 to 15 Wt. The exposure involves contacting a light guide to bladder wall wound tissues until visualising the coagulation changed within the contact exposure. That is combined with advancing the light guide spirally from the wound periphery to the tumour bed centre. A method involves improving the therapeutic effect by preventing the tumour recurrences, preventing erythrocyturia and developing complications caused by intraoperative complications, as well as preventing complications caused by the deep thermal exposure on the bladder wall.

EFFECT: improving the oncologic surgical effect is ensured by eliminating the tumour cell migration along the tumour bed vessels by the primary coagulation of the peripheral sections of the treated bed.
