Nocturnal enuresis—theoretic background and practical guidelines

Nocturnal polyuria, nocturnal detrusor overactivity and high arousal thresholds are central in the pathogenesis of enuresis. An underlying mechanism on the brainstem level is probably common to these mechanisms. Enuretic children have an increased risk for psychosocial comorbidity. The primary evaluation of the enuretic child is usually straightforward, with no radiology or invasive procedures required, and can be carried out by any adequately educated nurse or physician. The first-line treatment, once the few cases with underlying disorders, such as diabetes, kidney disease or urogenital malformations, have been ruled out, is the enuresis alarm, which has a definite curative potential but requires much work and motivation. For families not able to comply with the alarm, desmopressin should be the treatment of choice. In therapy-resistant cases, occult constipation needs to be ruled out, and then anticholinergic treatment—often combined with desmopressin—can be tried. In situations when all other treatments have failed, imipramine treatment is warranted, provided the cardiac risks are taken into account

Practical consensus guidelines for the management of enuresis

Despite the high prevalence of enuresis, the professional training of doctors in the evaluation and management of this condition is often minimal and/or inconsistent. Therefore, patient care is neither optimal nor efficient, which can have a profound impact on affected children and their families. Once comprehensive history taking and evaluation has eliminated daytime symptoms or comorbidities, monosymptomatic enuresis can be managed efficaciously in the majority of patients. Non-monosymptomatic enuresis is often a more complex condition; these patients may benefit from referral to specialty care centers. We outline two alternative strategies to determine the most appropriate course of care. The first is a basic assessment covering only the essential components of diagnostic investigation which can be carried out in one office visit. The second strategy includes several additional evaluations including completion of a voiding diary, which requires extra time during the initial consultation and two office visits before treatment or specialty referral is provided. This should yield greater success than first-line treatment. Conclusion: This guideline, endorsed by major international pediatric urology and nephrology societies, aims to equip a general pediatric practice in both primary and secondary care with simple yet comprehensive guidelines and practical tools (i.e., checklists, diary templates, and quick-reference flowcharts) for complete evaluation and successful treatment of enuresis
