Timer watch assisted urotherapy in children: a randomized controlled trial.

ABSTRACT

PURPOSE: We evaluated the effect of timer watch treatment in addition to standard urotherapy in children with overactive bladder and daytime urinary incontinence. MATERIALS AND METHODS: A total of 60 children with daytime urge incontinence were included in the study. Following a 4-week run-in period of standard urotherapy children were randomized to 12 weeks of standard urotherapy with or without a timer watch. Incontinence episodes were registered and 48-hour bladder diaries were obtained before randomization, and at weeks 1, 11 and 12. Long-term response was evaluated at 7 months. RESULTS: Two children became continent during the run-in period. Before intervention children in the timer group were slightly more wet than children in the standard urotherapy group (median 7 [IQR 25% to 75% 6 to 7] vs 6 [3 to 7] wet days per week, p <0.05). Following 12 weeks of standard urotherapy children randomized to timer assisted urotherapy had significantly fewer wet days per week (median 2, IQR 25% to 75% 0 to 5) vs those undergoing standard urotherapy alone (5, 2.75 to 6.75, p <0.01). In the timer group 18 children (60%) achieved a greater than 50% decrease in incontinence episodes, compared to only 5 (18%) treated without timer assistance. Nine patients (30%) in the timer group and no child in the standard urotherapy group achieved complete daytime continence. The timer increased compliance with the timed voiding regimen. At 7 months of followup 60% of children in the timer group were still continent in the daytime. CONCLUSIONS: A programmable timer watch significantly improves the effect of standard urotherapy. When using the timer watch as a supplement to standard urotherapy 60% of the children obtained complete and sustainable daytime continence.
