- The article describes the results of combined treatment of chronic bacterial cystitis caused by antibiotic-resistant strains of microorganisms, treatment combining endoscopic antimicrobial photodynamic therapy (aPDT) and antibiotic therapy. Methylene blue, the effect of which was potentiated by potassium iodide, was used as a photosensitizer for aPDT; antibiotic therapy drugs were administered due to the bacteriological analysis of urine. The patient underwent two aPDT sessions, each with a light dose of 28 J/cm 2 , antibiotic therapy being provided between them. The elimination of pathogenic microflora proved to be effective, stable remission of the disease being achieved.
