Key Findings
- Network meta-analysis of 18 RCTs (n=1649) comparing four treatment strategies for pediatric monosymptomatic nocturnal enuresis
- Desmopressin plus alarm combination showed the highest complete response rate, ranking first among all strategies
- Desmopressin plus anticholinergic agent ranked second for complete response
- Desmopressin monotherapy was superior to alarm therapy alone for short-term response
- Alarm therapy alone showed better long-term cure rates (lower relapse after discontinuation) compared to desmopressin alone
- The combination of desmopressin + alarm captures the benefits of both: rapid response (desmopressin) and durable cure (alarm conditioning)
Study Design
Network meta-analysis using Bayesian framework. Searched MEDLINE, Embase, Cochrane, and ClinicalTrials.gov for RCTs comparing desmopressin, alarm, desmopressin + alarm, and desmopressin + anticholinergic agents in children with monosymptomatic nocturnal enuresis. 18 RCTs met inclusion criteria. Primary outcome: complete response (defined as 14 consecutive dry nights). Treatment strategies ranked using surface under the cumulative ranking curve (SUCRA). Assessed inconsistency, heterogeneity, and publication bias.
Limitations
- Moderate heterogeneity across included studies in outcome definitions and follow-up periods
- Limited data on long-term outcomes (>6 months post-treatment) for most strategies
- Some comparisons in the network had few connecting studies
- Desmopressin dosing and formulations varied across trials
- Cannot fully account for differences in alarm device types and compliance
Clinical Relevance
This network meta-analysis is clinically important because it directly compares treatment strategies that are rarely tested head-to-head in individual RCTs. The finding that desmopressin + alarm is the most effective combination aligns with current ICCS (International Children's Continence Society) guidelines recommending combination therapy for refractory cases. For peptide therapy education, this study illustrates how a synthetic peptide (desmopressin) can be strategically combined with behavioral interventions for synergistic effects — a principle analogous to peptide stacking in other clinical contexts where pharmacological and non-pharmacological approaches complement each other.
