Efficacy of transcutaneous posterior tibial nerve stimulation in children with functional voiding disorders.

TPTNS is an efficient minimally invasive treatment in children with FVD who do not respond to medical treatment. TPTNS provides a significant improvement on episodes of frequency, episodes of incontinence, overall and day-time DVISS scores, and QoL scores. The effectiveness of treatment continues even at the end of the second year of intervention. UBs were not found to be predictive in terms of diagnosis and evaluating the treatment response.
