Abstract
The review article is devoted to the application of photodynamic therapy for non-muscle invasive bladder cancer. The data on the mechanism and pathogenetic bases of the application of this method of treatment, the method of its implementation, the advantages and disadvantages of the photosensitizers and the results of clinical studies are presented. It has been shown that intraoperative photodynamic therapy significantly reduces the rate of recurrence of bladder cancer after transurethral resection, including in patients with carcinoma in situ and multifocal growth of urothelial tumors.
