Abstract

© 2025 Wiley Periodicals LLC.Aims: Recurrent urinary tract infections are a common medical problem and current guidelines recommend both antibiotic and non-antibiotic preventative treatments. However, for a significant proportion of patients with this condition these second-line treatments are not effective. As a result, there has been recent focus on more targeted treatment such as intravesical instillations and bladder fulguration procedures. We aim to report discussions regarding these targeted treatments for recurrent urinary tract infections that took place at the International Consultation on Incontinence - Research Society meeting in Bristol 2025. Methods: We undertook a think-tank session during this multi-disciplinary meeting specifically designated for discussion regarding targeted treatments for UTI prevention. We discussed the incidence and prevalence of recurrent UTIs in the general population and recognise that up to 25% of patients are not adequately treated with currently recommended preventive strategies. We also explored the increasing knowledge base surrounding the urinary microbiome and discussed the concept of chronic urinary tract infection. Finally we outlined the current evidence to support the use of the targeted treatments of intravesical instillation of both antibiotics and glycosaminoglycan (GAG) replacement compounds and the surgical procedure of bladder fulguration. This led to the generation of research ideas which hope to shape future UTI research within this topic area. Results: We describe the discussions that took place and document the important research questions that were generated during the International Consultation on Incontinence—Research Society meeting in Bristol 2025. Conclusions: Although the use of targeted treatments is becoming more widespread the evidence base is currently insufficient for strong guideline recommendation. This must be balanced against the significant need for second-line treatments when current guideline recommended treatments are unsuccessful, particularly in the design of clinical pathways for patients with refractory recurrent UTIs.
