Brief summary

The absence of infectious, urological and neurological causes defines the idiopathic character of overactive bladder (OAB). Although a progressive approach starting with behavioural therapy (urotherapy) is recommended, anticholinergic agents remain the mainstay of medical treatment of overactive bladder (OAB) in children. Bladder neuromodulation is also used but no study with sufficient evidence has assessed its effectiveness and tolerance compared to the reference treatment. The purpose of HAV-O-TENS is to demonstrate the non-inferiority of treating idiopathic overactive bladder (OAB) in children using posterior tibial nerve stimulation (PTNS) compared to the reference treatment with oxybutynin after three months of treatment. Before inclusion, patients will receive instructions for urotherapy and a treatment plan. After confirming the diagnosis and obtaining informed consent, patients will be randomly assigned to either oxybutynin or PTNS (posterior tibial nerve stimulation) treatment, and their effectiveness, tolerance, and adherence will be monitored.

Design outcomes

Primary

MeasureTime frameDescription
Variation of DVISS score between PTNS treatment group and oxybutynin groupat 3 monthsDVISS score is : Dysfunctional Voiding and Incontinence Symptoms Score (DVISS) Questionnaire. The DVISS is a 13-item instrument that includes 1 QOL question. The first 5 questions are scored using an ordinal scale with the remainder in binary format. The DVISS scores are based on the estimated odds ratio (OR) for each question between cases and controls. For example, a score of 1 is given if the item's OR is between 2 and 10, and a score of 5 is given if the OR is greater than 50. The total score can range from 0 to 35 with a cutoff score of 8.5 having 90% sensitivity and specificity at detecting BBD.

Secondary

MeasureTime frameDescription
variation of time to treatment efficacy between both groupsat 6 months
variation of tolerance between both groupsat 3 months
variation of treatment duration between both groupsat 6 months
variation of long-term efficacy between both groupsat 12 months
variation of long-term efficacy of AOB frequency between both groupsat 24 monthsLong term efficacy of OAB frequency is measured with DVISS score. The DVISS is a 13-item instrument that includes 1 QOL question. The first 5 questions are scored using an ordinal scale with the remainder in binary format. The DVISS scores are based on the estimated odds ratio (OR) for each question between cases and controls.
