Nocturnal enuresis (NE), commonly known as bed-wetting, affects a significant number of school-age children and can have profound effects on self-esteem, sleep, and family dynamics. An updated expert consensus, published in the World Journal of Pediatrics, provides a comprehensive framework for diagnosing and managing this condition, aiming to standardize care and improve outcomes.
The new guidance, developed by researchers from the Children's Hospital of Fudan University and the Chinese Cooperative Group for the Management of Pediatric NE, lowers the diagnostic threshold. Children aged five years and older who experience at least one involuntary nighttime void per month for three months now meet the criteria, a shift from the previous weekly standard. This change allows for earlier intervention, potentially reducing the psychological and social burden associated with the condition.
A key aspect of the consensus is the clear distinction between monosymptomatic NE (MNE), where no daytime urinary symptoms are present, and non-monosymptomatic NE (NMNE), which includes daytime symptoms such as urgency or incontinence. This classification is crucial for guiding treatment decisions. The voiding diary is highlighted as a diagnostic cornerstone, requiring patients to record at least two daytime charts and seven consecutive nights of fluid intake and voids. This allows clinicians to phenotype children as having nocturnal polyuria, reduced bladder capacity, or a combination, leading to more targeted therapy.
For MNE, first-line treatment is phenotype-driven: desmopressin for nocturnal polyuria and the enuresis alarm for reduced bladder capacity, with combination therapy for mixed types. For NMNE, the focus shifts to managing daytime lower urinary tract symptoms and comorbidities, particularly constipation, which affects 36-80% of these children. The consensus also outlines clear referral criteria, advising that primary care can manage MNE, but non-responders or suspected NMNE should be evaluated by specialists, potentially including urodynamics and lumbosacral MRI. For refractory cases, defined as less than 50% improvement after three months, a systematic re-evaluation is recommended before escalating treatment.
The authors emphasize that NE should not be treated as a single disorder. Instead, clinicians should identify the child's specific pattern, consider daytime symptoms and comorbidities, and match treatment to the underlying mechanism while involving the family. This approach aims to reduce trial-and-error treatment and improve response rates by addressing issues like constipation, sleep-disordered breathing, and ADHD earlier.
The recommendations have practical implications for pediatricians and primary-care providers, helping them distinguish between children who can be managed locally and those needing specialist care. By promoting the use of voiding diaries and symptom-based classification, the consensus seeks to enhance care coordination and ensure timely referrals. While some recommendations reflect Chinese practice patterns and evidence gaps remain, such as desmopressin withdrawal strategies, the framework represents a significant step toward more systematic and individualized care for children with nocturnal enuresis.
