OBJECTIVE: Parasacral TENS and PTNS have emerged as effective methods to treat overactive bladder in children.
To the best of our knowledge, however, no study has compared the two methods. The objective of this study is to evaluate the results of parasacral TENS and PTNS in children with OAB.
MATERIALS AND METHODS: This is a prospective study of children with OAB and without dysfunctional voiding. Success of treatment was evaluated using the VAS, the DVSS, and by the level of improvement of each specific symptom. Parasacral TENS was performed three times per week and PTNS was performed once per week.
RESULTS: 22 consecutive patients were treated by PTNS and 37 by TENS. There was no difference between the two groups with respect to demographic characteristics and symptom types. Regarding the evaluation by VAS, a complete resolution of symptoms was seen in 70% of the group who underwent parasacral TENS and 9% of the group who underwent PTNS (p = 0.02). When the groups were compared, there was no statistically significant difference (p = 0.55). The frequency of persistence of urgency and diurnal urinary incontinence was nearly double in the group that underwent PTNS treatment. However this difference was not statistically significant.
CONCLUSIONS: We found that parasacral TENS is more effective in the resolution of the OAB symptoms, which matches the parents' perception of their children. However, there was no statistically significant difference in the evaluation by DVSS nor in the complete resolution of urgency and diurnal incontinence.
