Abstract

Introduction and hypothesis: Intravesical antimicrobials (IVA) provide a localized modality of treatment for recurrent urinary tract infections (rUTIs). Owing to the sporadic use of these treatments, we conducted a systematic review on the efficacy of IVA in the management of uncomplicated rUTIs. Methods: A systematic review was conducted for all English language articles from inception to April 2021 utilizing the Cochrane and Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards with the following databases: PubMed, OVID Embase, Biomed Central, and Scopus. References were cross-examined for further articles. Risk of bias was assessed in the articles included using the Cochrane and Joanna Briggs Institute tools. Results: The initial search resulting in 476 titles led to 15 full-text articles. Of the 13 in the final review (2 RCTs), 3 used gentamicin and 10 used hyaluronic acid IVA. These included 764 participants, mostly women, with a mean age range of 27–80 (median: 53.1). There was a reduction in UTI frequency in 12 out of 13 studies, with 10 studies showing a statistically significant decrease. Dosages of 80 mg of gentamicin per instillation and both 40 mg and 800 mg of hyaluronic acid per instillation were found to be effective in reducing the frequency of UTIs in most studies. Eleven participants reported gentamicin-resistant infections after IVA treatment. Despite high levels of bias in selected categories, the 13 studies were designated to be of high quality for inclusion. Conclusions: The IVAs gentamicin and hyaluronic acid with chondroitin sulphate demonstrated efficacy in the management of uncomplicated rUTIs, mostly in women.
