Abstract: The urinary tract (UT) was once considered sterile, but now it is known to host a diverse
community of microorganisms, known as the urinary microbiome. The collective microbiota is
made up of bacteria, fungi, and viruses, necessary for maintaining UT health. This review aims to
synthesize current knowledge on the urinary microbiome and clarify its emerging role as a key
modulator in both health and a wide spectrum of UT disorders. Dysbiosis within this microbial
community has been linked to conditions such as urinary tract infections (UTIs), interstitial cystitis/
bladder pain syndrome (IC/BPS), urinary incontinence, urolithiasis, benign prostatic hyperplasia
(BPH), and even urinary tract malignancies. Advances in methodologies, such as expanded quantitative
urine culture and metagenomics, have provided valuable insights into microbial variability influenced
by factors like age, sex, and disease conditions. Additionally, this review explores the therapeutic
potential of probiotics and bacteriophages, as well as the association of urinary microbiota
with autoimmune and inflammatory conditions. Special emphasis is placed on translational relevance,
including emerging microbiome-targeted therapies and personalized interventions for UTIs.
Ethical considerations allied with UT microbiome research, such as data privacy, informed consent,
and equitable access to emerging therapies, are also discussed. Despite substantial progress, challenges
such as methodological heterogeneity, a lack of longitudinal data, and unresolved causal relationships
persist. The study concludes by identifying key knowledge gaps and proposing future directions
for multidisciplinary research to advance therapeutic innovation in urological health.
