Factors associated with response to simple behavioral intervention in primary enuresis nocturna.

This 8-week longitudinal study examined predictors of response to simple behavioral intervention in primary enuresis nocturna (PEN). A total of 154 children, aged 8-18 years, diagnosed with PEN were evaluated. The results indicated that lack of constipation, milder enuresis severity, and higher bladder capacity are the primary predictors of good treatment response, and lower family dysfunction is the most robust familial predictor. Lack of constipation is the main predictor with unique variance in multiple regression. Specialists should be aware of conditions that hinder the success of simple behavioral intervention before implementing costly treatments. In treatment-refractory cases, it is important to examine each child for constipation. Family-centered approaches can be helpful if used in parallel with behavioral treatments.
