PURPOSE
Parasacral Transcutaneous electrical nerve stimulation (TENS) is an effective method in the treat-
ment of overactive bladder in children. We have performed this procedure with sessions of 20 min-
utes, 3 times per week. However, the ideal number of sessions per week is not well established.
Fewer sessions would be more suitable to patients and reduce costs. The aim of this study is to
compare TENS parasacral held 3 vs.2 times a week.
MATERIAL AND METHODS
This is a randomized clinical trial. Inclusion criteria: Patients with urgency, urinary flow with bell or
tower shape and low post-voiding residual urine.
Patients were randomly allocated to 2 groups: A) Parasacral TENS 3x/week, B) 2x/week. Sessions
lasted 20 minutes. The result was evaluated by visual analogical scale (VAS). Below 50% improve-
ment would be poor response, of 50% to 90% was partial and 100% complete response. They were
also evaluated by DVSS. The results were compared by Fisher’s exact test for categorical variables
and Mann-Whitney test for continuous variables.
RESULTS
34 children were allocated (22 girls) aged 4-14 years: 18 in group A and 16 in group B. Ten children
were constipated before treatment. With respect to VAS, in the group A 11 group had a complete
response, 6 had partial response and 1 with little response. In group B 8 had complete response,
6 had partial and 2 had poor response. Both evolved with significant improvement in DVSS after
treatment, but there was no significant difference between groups (p = 0.618). No difference in the
rate of improvement of enuresis and constipation was found.
CONCLUSIONS
This study shows that it is possible to treat patients with parasacral TENS 2x / week without com-
promising significantly the outcome. A larger number of patients would be required to define that this
number of sessions per week is the ideal.
