ABSTRACT
BACKGROUND: Lower urinary tract dysfunction (LUTD) is a broad term describing the full spectrum of disorders in any of the stages of bladder function-storage or voiding LUTD is a clinical condition associated with emotional and behavioral disorders in children. This cross-sectional study aimed to investigate the association of emotional and behavioral symptoms and their impact on the quality of life (QoL) in children and adolescents with LUTD. METHODS: Eighty-eight patients and their parents enrolled in an interdisciplinary program for children and adolescents with LUTD were included in the analysis. Child Behavior Checklist (CBCL) was used to estimate the prevalence of behavioral and emotional problems through the assessment of 14 items. Pediatric Quality of Life Inventory (versions for parents and children) was applied in the versions for parents and children to evaluate the QoL. The Pediatric Quality of Life Inventory-PedsQL, version 4.0-was applied separately for parents and patients. The association of clinical variables and aspects related to QoL of patients were evaluated through non-parametric correlations (Spearman) and multiple linear regression analysis. RESULTS: According to CBCL's clinical scores, 56% of the patients showed total behavioral problems, 55% internalizing, and 38% externalizing. When comparing the conditions of LUTD and the CBCL scores, patients with voiding postponement had the lowest rates of total problems (P = 0.036). Children and adolescents with LUTD who also had enuresis showed a higher frequency of externalizing problems (P = 0.001), especially aggressive behavior (P = 0.013). Scores of patients with LUTD were significantly lower in all domains of QoL than normative data. Presence of behavioral problems was associated with worse QoL in all evaluated aspects. The total QoL was most influenced by the CBCL school competence scale according to the regression model analysis. CONCLUSIONS: The study findings suggest the relevance of evaluation of behavioral and social repercussions of LUTD to improve the multidisciplinary approach for this condition in pediatric population.
