Management of Uncomplicated Urinary Tract Infection in the Post-Antibiotic Era: Select Non-Antibiotic Approaches.

BACKGROUND:Given the high frequency of patients presenting with urinary tract infections (UTIs) and the ensuing high degree of antibiotic prescription, UTI is a critical point of intervention for non-antibiotic treatments to curb the further development of antimicrobial resistance and provide risk-appropriate care for patients.OBJECTIVES:To highlight several select non-antibiotic therapies for the treatment of uncomplicated UTI and relevant indications (prevention and complicated UTI) from recent literature.SOURCES:PubMed, Google Scholar, and clinicaltrials.gov were searched for clinical trials published in the English language corresponding to non-antibiotic treatments for UTI.CONTENT:The focus of this narrative review centres on a limited number of non-antibiotic therapies for the treatment of UTI based on (a) herbal extracts or (b) antibacterial strategies (e.g. bacteriophage therapy and D-mannose). The experience of treatment with non-steroidal anti-inflammatory drugs is also used to fuel discussion on the risk of developing pyelonephritis without antibiotics-compared with the projected harms of continuing their widespread use.IMPLICATIONS:Non-antibiotic treatment strategies for UTI have shown varying results in clinical trials, and the current evidence does not yet indicate a clear, better alternative to antibiotics. However, the collective experience with non-antibiotic treatments suggests that there is a need to weigh the actual benefits/risks of unfettered, non-culture-confirmed antibiotic use in uncomplicated UTI. Given the different mechanisms of action of proposed alternatives, more in-depth knowledge on microbiological and pathophysiological factors influencing UTI susceptibility and prognostic indicators are highly needed to stratify patients most likely to benefit. The feasibility of alternatives in clinical practice should also be considered.
