PURPOSE
Despite adequate empiric management, 20 % of children with overactive bladder (OAB) fail
to improve. An inpatient bladder rehabilitation program (voiding school) was established, as an
alternative strategy for refractory OAB in children. The aim was to evaluate the long-term outcome
of the voiding school program.
MATERIAL AND METHODS
A retrospective chart review of 357 children with refractory OAB, who attended voiding school be-
tween 2000 and 2010 was performed. Children were between 5 and 16 years old (mean 9.7 years,
SD 2.0), 227 (63,6 %) were boys. Outcome was evaluated at 6 time points, until one year after void-
ing school, measuring continence, enuresis and daytime incontinence voiding scores (respectively
eVS and dVS) and maximal voiding volume (MVV). Linear mixed models were used to account for
the longitudinal character of the data.
RESULTS
Voiding school in children with refractory OAB resulted in a spectacular increase of continence
(<1 % at entry to 26.6 % 1 year after voiding school). Moreover, a decline in the proportion of
children (68.2 % to 22.9 %) with combined daytime & night incontinence, and of the severity of
the incontinence was seen. Young boys with comorbid nocturnal polyuria, dysfunctional voiding or
faecal incontinence had the most unfavourable evolution.
CONCLUSIONS
Voiding school is a successful treatment modality for children with refractory OAB and resulted in
a spectacularly increase of dryness. Additionally, voiding school introduced an important shift from
combined and severe to isolated and mild forms of incontinence, with good long-term effects.
