Conditions

Primary Monosymptomatic Nocturnal Enuresis

Brief summary

This randomized controlled trial will evaluate whether restricting bedtime digital-device use improves the response to desmopressin in children with primary monosymptomatic nocturnal enuresis. Participants will receive desmopressin for 8 weeks and will be assigned to either bedtime device restriction or usual screen habits.

Detailed description

This is a prospective, parallel-group, open-label randomized controlled trial conducted at Al-Hussein and Sayed Galal Hospitals, Al-Azhar University, Cairo, Egypt. Children aged 6-14 years with primary monosymptomatic nocturnal enuresis will be enrolled and randomized 1:1 to receive desmopressin plus bedtime digital-device restriction or desmopressin with no restriction. The intervention group will avoid digital devices, including smartphones, tablets, televisions, computers, and video games, for at least 60 minutes before habitual bedtime. The control group will continue the usual screen habits. All participants will receive oral desmopressin at bedtime for 8 weeks, with dose adjustment allowed according to clinical response. The primary outcome is the proportion of participants achieving full response, defined as no more than 1 wet night during the last 2 weeks of treatment. Secondary outcomes include reduction in wet nights per week, partial response rate, sleep quality, adherence, and relapse 4 weeks after treatment discontinuation. Baseline demographic, clinical, and sleep-related data will also be collected to explore predictors of treatment response.

Adherence to Bedtime Device RestrictionDuring the 8-week treatment periodProportion of nights in which participants in the intervention group avoided digital-device use for at least 60 minutes before bedtime, based on parental log.
Desmopressin AdherenceDuring the 8-week treatment period.Proportion of prescribed desmopressin doses taken during the 8-week treatment period, based on parental report and pill count.
Adverse Effects of DesmopressinDuring the 8-week treatment period and 4 weeks after treatment discontinuationProportion of participants experiencing adverse effects related to desmopressin, including headache, nausea, vomiting, hyponatremia symptoms, excessive thirst, fluid retention, or any other treatment-emergent adverse event.
