[Biofilm control in urological practice].

Urinary tract infections (UTIs) have long been among the most common diseases. In the structure of the general infectious morbidity, UTIs rank second after acute respiratory viral infection. Every year, researchers note an increasing number of mutations in the genomes of bacteria that cause infectious diseases, which leads to the formation of more and more aggressive forms of pathogens. Patients with infectious diseases of the urinary system have the highest risk of biofilm formation, the frequency of which is directly proportional to the length of time the urethral catheter is located and accounts for more than half of all nosocomial infections. The presence of resistant strains of pathogenic bacteria and the development of bacterial biofilms are major problems in the treatment of urinary tract infections. The increasing number of nosocomial bacterial strains in the hospital increases the postoperative bed-day, the frequency of readmission and the number of antibacterial drugs used. In light of increasing antibacterial resistance, the use of medical resources is dramatically increasing, which ultimately leads to an increase in the cost of treatment. Along with this, the selection of resistant strains brings to the fore both the rational use of antibacterial drugs and the search for alternative methods of therapy. This review of publications on the problem of bacterial biofilm formation in urological practice demonstrates updated information on the role of enzymes, probiotics, and bacteriophages in preventing biofilm formation on various medical biomaterials, such as urethral catheters.
