Purpose: To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder.
Materials and Methods: A search was made of the institute’s database for all patients diagnosed with overactive bladder over the preceding four years. Children and adoles¬cents under 18 years of age with overactive bladder and no neurological or anatomi¬cal alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the pres¬ence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify pa¬tients with febrile UTI and subsequently determine predictors of this condition. Uni¬variate and multivariate analyses were performed.
Results: Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses.
Conclusions: These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.
