ABSTRACT
INTRODUCTION AND

HYPOTHESIS:

The objective was to systemically review the current literature on the association of gut, vaginal, and urinary dysbiosis in female patients with overactive bladder (OAB).

METHODS:

We performed a comprehensive literature search following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) protocols for systematic reviews. In the EMBASE, CINAHL, and Medline databases, a search was conducted using key words such as "microbiome," "microbiota," "microflora," "overactive bladder," "urge," "gut," "vaginal." Articles were screened using the online tool www.covidence.org . Two independent reviewers screened studies at each stage and resolved conflicts together. We excluded papers that discussed pediatric patients and animal studies. In total, 13 articles met this criterion, which included 6 abstracts.

RESULTS:

After identifying 817 unique references, 13 articles met the criteria for data extraction. Articles were published from 2017 to 2021. No study reported the same microbiota abundance, even in healthy individuals. Overall, there was a loss of bacterial diversity in OAB patients compared with controls. Additionally, the bacterial composition of the controls and OAB patients was not significantly different, especially if the urine was collected midstream. Overall, the composition of the microbiome is dependent on the specimen collection methodology, and the metagenomic sequencing technique utilized. OAB urine microbiome is more predisposed to alteration from the gut or vaginal influences than in controls.

CONCLUSIONS:

Current evidence suggested a potential relationship among gut, vaginal, and urinary microbiome in OAB patients, but there are very limited studies.
