CONTEXT: A high relapse rate after discontinuation of desmopressin treatment of pediatric enuresis is consistently reported. Structured withdrawal strategies have been used to prevent relapse.
OBJECTIVE: To assess the efficacy of a structured withdrawal strategy of desmopressin on the relapse-free rate for desmopressin responder pediatric enuresis.
DATA SOURCES: Systematic literature search up to November 2015 on Medline, Embase, Ovid, Science Direct, Google Scholar, Wiley Online Library databases, and related references without language restriction.
STUDY SELECTION: Related clinical trials were summarized for systematic review. Randomized controlled trials on the efficacy of structured versus abrupt withdrawal of desmopressin in sustaining relapse-freestatus in pediatric enuresis were included for meta-analysis.
DATA EXTRACTION: Eligible studies were evaluated according to Cochrane Collaboration recommendations. Relapse-free rate was extracted for relative risk (RR) and 95% confidence interval (CI). Effect estimates were pooled via the Mantel-Haenszel method with random effect model.
RESULTS: Six hundred one abstracts were reviewed. Four randomized controlled trials (total 500 subjects) of adequate methodological quality were included for meta-analysis. Pooled effect estimates compared with the abrupt withdrawal, structured withdrawal results to a significantly better relapse-free rate (pooled RR: 1.38; 95% CI, 1.17-1.63; P = .0001). Subgroup analysis for a dose-dependent structured withdrawal regimen showed a significantly better relapse-free rate (pooled RR: 1.48; 95% CI, 1.21-1.80; P = .0001).
LIMITATIONS: The small number of studies included in meta-analysis represents a major limitation.
CONCLUSIONS: Structured withdrawal of desmopressin results in better relapse-free rates. Specifically, the dose-dependent structured withdrawal regimen showed significantly better outcomes.
