Treatment of primary nocturnal enuresis in children: a review

Primary nocturnal enuresis is a common childhood disorder. Treatment approaches bridge the psychological and medical fields. A substantial body of literature addresses the various ways of treating enuresis, from pharmaceuticals to behavioural interventions. The medical and psychological literatures have proceeded relatively independently from one another and there has been little interconnection between the US and international literatures, resulting in a lack of discourse and integration among researchers investigating treatment outcomes for enuresis. This review examined the evidence base for treatments of primary nocturnal enuresis in children. Psychological, pharmaceutical and multi-component interventions are discussed. This review sought to provide an integrated interdisciplinary and international perspective on treatment efficacy for nocturnal enuresis by expressly gathering publications from psychological and medical fields, as well as US and international sources. The literature supported the urine alarm as the most effective intervention for nocturnal enuresis and demonstrated the benefit of combining the urine alarm with other components, both behavioural and pharmaceutical. In particular, recent literature showed that the urine alarm, when used in conjunction with antidiuretic medication (i.e. desmopressin), leads to more dry nights earlier in the conditioning process. Disparities between the different literatures were discussed.
