Objective: Evaluate clinical aspects associated with the presence of nocturnal enuresis (NE) in children with a diagnosis of overactive bladder (OAB).
Material and Methods: A data base of 200 children who were evaluated by a structured questionnaire was analysed retrospectively . OAB was defined as the presence of urinary urgency (n=183 cases) and/or daytime urinary incontinence associated with holding maneuvers (n=168 cases). Inclusion criteria were a confirmed diagnosis of OAB, age 5-16 years, and no anatomical or neurological alterations of the urinary tract. Patients were divided into enuretics and non-enuretics. The two groups were compared with respect to sex, age, skin color, presence urinary infection, urgency, urge incontinence, non-urge incontinence, pollakiuria, urinary dysfunction, nocturia, holding maneuvers, number of episodes of enuresis and bowel alterations. In a univariate analysis, the chi-square test was used to compare proportions, with p-values <0.05 being considered significant. A multivariate analysis was conducted to identify independent predictive factors.
Results: Enuresis was diagnosed in 141/200 children. The two groups were similar with respect to sex, age and skin color. No difference was found in relation to urinary infection, non-urge incontinence, urinary dysfunction, nocturia, encopresis or constipation.
The two groups were significantly different with regard to some symptoms related to OAB such as urgency (p=0.001), urge incontinency (p=0.001) and holding maneuvers (p=0.033). Following multivariate analysis, only holding maneuvers (p=0.022) remained as an independent predictive factor.
Conclusion: The only independent predictive factor for resolution of enuresis in children with OAB, as detected in the multivariate analysis, was holding maneuvers.
