Key Takeaway
Recognize oral microbiota links to urinary diseases and caries risk as associations without causal proof

This publication is a systematic review examining the relationship between oral microbiota and urinary system diseases. The scope encompasses general and pediatric populations, specifically addressing chronic kidney disease, Henoch-Schönlein purpura nephritis, and early childhood caries. The authors synthesize accumulating evidence indicating that oral microbiota contribute to the pathogenesis of urinary system diseases.

Key findings highlight clinical observations linking untreated early childhood caries to an increased risk of Henoch-Schönlein purpura nephritis. The review discusses underlying mechanisms and associations rather than establishing definitive causal relationships through randomized trials. No specific statistical data, such as p-values or confidence intervals, were reported in the abstract to quantify these associations. The sample size and follow-up duration were not reported in the provided data.

The authors note that the source summarizes literature rather than presenting primary clinical trial data. Limitations include the absence of specific statistical metrics and the observational nature of the synthesized evidence. Consequently, the findings should be interpreted as associations rather than proven causal pathways. The review explicitly states it does not provide specific statistical data.

Practice relevance involves potential implications for the prevention, diagnosis, and management of urinary system disorders. Clinicians should recognize these links while acknowledging the evidence level remains at the systematic review stage without primary trial validation. Safety data regarding adverse events were not reported in the abstract.

The human oral microbiome has attracted considerable attention due to its role in oral health and potential implications for systemic diseases. Oral microbes provide real-time insights into health and disease status, making them valuable for early disease risk stratification and treatment outcome prediction. Accumulating evidence indicates that oral microbiota contribute to the pathogenesis of urinary system diseases. Notably, in pediatric populations, the oral microbiome—shaped by age, feeding patterns, and immune maturation—may modulate susceptibility to renal-related systemic conditions; clinical observations specifically link untreated early childhood caries to an increased risk of Henoch-Schönlein purpura nephritis (HSPN). This review critically appraises the existing literature to clarify the nature and magnitude of the association between the oral microbiome and urinary system diseases, including chronic kidney disease, urolithiasis, benign prostatic hyperplasia, and urologic cancers, as well as pediatric HSPN. We also analyze the potential mechanisms through which the oral microbiota are involved in the pathogenesis and progression of these relevant diseases, and explore its potential implications for the prevention, diagnosis, and management of urinary system disorders.
