Abstract

Purpose
To assess the efficacy of desmopressin plus anticholinergic combination therapy as first-line treatment for children with primary monosymptomatic nocturnal enuresis (PMNE) and to analyze this combination’s effect on functional bladder capacity (FBC).
Materials and Methods
A total of 99 children with PMNE were prospectively enrolled from 2015 to 2019 and randomly allocated to a monotherapy group (n=49), with oral desmopressin lyophilisate (MELT) only; and a combination group (n=50), with desmopressin plus an anticholinergic (propiverine 5 mg). Efficacy and FBC were evaluated at 1 and 3 months after treatment initiation; the relapse rate was assessed at 6 months after treatment cessation.
Results
The combination therapy group showed a higher rate of complete response than the monotherapy group after 3 months of treatment (44.0% vs. 22.4%, p=0.002). A significant increase in mean FBC was observed only in the combination group, from 88.72±26.34 mL at baseline to 115.52±42.23 mL at 3 months of treatment (p=0.024). Combination therapy was significantly associated with treatment success at 3 months after treatment initiation (odds ratio [OR], 3.527; 95% confidence interval [CI], 1.203– 6.983; p=0.011) and decreased risk of relapse at 6 months after treatment cessation (OR, 0.306; 95% CI, 0.213–0.894; p=0.021), by multivariable analysis.
Conclusions
This study represents the first prospective, randomized controlled trial showing higher response rates and lower relapse rates with desmopressin plus anticholinergic combination therapy compared with desmopressin monotherapy as first-line treatment for children with PMNE.
