PURPOSE
Day and night-time urinary incontinence secondary to overactive bladder (OAB) is a disorder
frequently observed in children. Current therapies include urotherapy and anti-muscarinic drugs,
however both have shown poor outcomes. Recently, transcutaneous electric nerve stimulation
(TENS) has been demonstrated successful treatment for OAB. We aimed to assess compliance
and success of TENS in our population
MATERIAL AND METHODS
We randomly selected a cohort of patients from our prospectively maintained database. Patients
were prescribed TENS treatment for a maximum of 84 days. A bladder-voiding diary was completed
by parents. Patients were followed-up 3 months after the initiation of treatment. Demographic data
including age, gender and BMI were collected. Outcome parameters included: resolution of symp-
toms, length of treatment and compliance. We analysed results dividing patients based on compli-
ance (table 2) and BMI (table 3: Underweight (BMI<18.5), normal (18.5< BMI < 25), Overweight
(BMI > 25)).

CONCLUSIONS
Partial/complete response was obtained in half of the patients in the analysed cohort. Compliance
was high (85%). Nor BMI or compliance significantly influenced the success of the treatment.
