Non-bacterial urinary tract infections (UTIs) remain a critically understudied domain within urology and infectious disease, overshadowed by the well-characterized bacterial paradigm despite their significant clinical impact. This review provides an exhaustive analysis of non-bacterial UTIs, encompassing viral (e.g., adenovirus, BK virus), fungal (e.g., Candida spp.), parasitic (e.g., Schistosoma haematobium), and non-infectious etiologies (e.g., interstitial cystitis, chemical irritants, autoimmune conditions). These conditions often evade conventional diagnostics, leading to misdiagnosis, inappropriate antibiotic use, and chronic patient suffering. We explore the pivotal roles of the urinary microbiome and immune dysregulation, integrating cutting-edge research on dysbiosis, neuroimmune interactions, and environmental triggers. Diagnostic challenges are dissected alongside innovative solutions, including metagenomics, AI-driven tools, and novel biomarkers. Therapeutically, we propose a multifaceted approach – pathogen-specific treatments, immunomodulation, microbiome restoration, and patient-centered strategies supported by emerging modalities like nanoparticle drug delivery and dietary interventions. Enhanced clinician awareness and standardized protocols are advocated to combat antimicrobial resistance and improve outcomes. This expansive review, enriched with multidisciplinary insights and forward-thinking proposals, seeks to galvanize global research efforts to address the complexities of non-bacterial UTIs comprehensively.
