摘要

Purpose of Review

Neuropsychiatric disorders frequently co-occur with lower urinary tract symptoms (LUTS) in children, with prevalence rates for behavioral and psychological problems reaching 20–40% in those with elimination disorders. Notably, attention-deficit/hyperactivity disorder (ADHD) affects nearly 25% of children with daytime wetting. This strong association is increasingly understood through shared neurobiological underpinnings.

Recent Findings

Genetic studies reveal links between specific genes associated with anxiety and nocturnal enuresis, while epigenetics demonstrates how early life stress can induce methylation changes in genes critical for brain development and stress response, influencing bladder function. Neuroimaging has elucidated a common neuroanatomical basis. Brain regions such as the insula, anterior cingulate cortex (ACC), and prefrontal cortex (PFC), vital for both micturition control and executive functions, show structural and functional abnormalities in children with LUTS and neuropsychiatric conditions like schizophrenia and depression. Cortical thinning in the right frontal lobe, for instance, correlates with both urinary incontinence and depression. A distinct clinical phenotype, "wetting without sensory awareness," is often observed in children, reflecting dysfunction in major attention and default mode networks, particularly in ADHD. Pharmacological interventions targeting central neurotransmitter systems, rather than solely peripheral bladder mechanisms, have shown efficacy. Tricyclics, A2 agonists, norepinephrine reuptake inhibitors, and serotonin reuptake inhibitors demonstrate benefit by modulating central pathways affecting bladder control, often through ACC or frontal lobe activation. However, medications like norepinephrine reuptake inhibitors and sympathomimetics, while centrally beneficial, can cause peripheral bladder neck tightening, leading to voiding difficulties.

Summary

This complex interplay necessitates a holistic, neurobiologically informed approach to diagnosis and management, recognizing LUTS as manifestations of broader neurodevelopmental vulnerabilities.
