According to A. D. Caprin et al., [1] out of 3 630 567 patients, uterus cancer accounts for 7,1%; prostate — 6,1%; cervix — 4,9%; rectum — 4,4%; bladder — 2,99%. 30 to 50 per cent of all these patients require radiotherapy with high summary doses, palliative or symptomatic irradiation. Radiation-induced cystitis is diagnosed for in a range of 20 to 80%. Amount of publications concerning various methods of treatment of this pathology — systemic, local, using physical and different combinations — shows that there is no solid concept for prophylactics and treating of this adverse side effect of radiotherapy.
