RESUMEN
AIM: To analyze uroflowmetry as a predictor of the outcome of treatment with parasacral transcutaneous electrical nerve stimulation (TENS) in patients with pure overactive bladder. METHODS: Thirty-eight patients of 5-16 years of age were included in this prospective cohort study. All the patients had been seen at a referral clinic between 2006 and 2015. All had a diagnosis of pure overactive bladder and were treated with TENS. Parameters established at pretreatment uroflowmetry were evaluated, with patients then being separated into two groups based on their visual analogue scale (VAS) score immediately following TENS. The variables analyzed at uroflowmetry were: maximum flow rate, curve pattern (bell or tower-shaped), time until maximum flow and voided volume. RESULTS: The mean age of the children evaluated was 7.26 years (SD: 2.62) (95%CI: 6.4-8.13) and 73.7% were girls. No association was found between maximum flow rate, curve pattern (bell or tower-shaped) or voided volume and the complete resolution of symptoms following treatment. Nevertheless, a shorter time until maximum flow was associated with a greater likelihood of treatment failure. CONCLUSION: The time until maximum flow rate before treatment is a potential predictor of the outcome of TENS treatment.

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.
