Quality of life and psychological aspects in children with overactive bladder treated with parasacral transcutaneous electrical nerve stimulation - A prospective multicenter study.

Objective: To assess the impact of parasacral transcutaneous electrical nerve stimulation (parasacral TENS) on quality of life (QoL) and psychological aspects in children treated for overactive bladder (OAB).

Methods: This international, multicenter, prospective cohort study involved individuals of 6-16 years of age under TENS treatment for OAB. The study was conducted between June 2016 and December 2019 in four participating centers: two in Australia, one in Germany and one in Brazil. Patients with anatomical and/or neurological abnormalities of the urinary tract were excluded. Questionnaires were applied before and after parasacral TENS treatment: the Dysfunctional Voiding Symptom Score (DVSS), used in Brazil, or the International Consultation on Incontinence Questionnaire - Pediatric Lower Urinary Tract Symptoms (ICIQ-CLUTS), used in Germany and Australia, to analyze urinary symptoms; the Strengths and Difficulties Questionnaire (SDQ) to assess emotional and behavioral aspects; and the Pediatric Incontinence Questionnaire (PinQ) for bladder-specific Qol.

Results: Fifty-three patients (28 girls and 25 boys) with a mean age of 8.64 ± 2.63 years were included. Median DVSS was 11 (range 6-13.5) and 3 (range 0-7), (p < 0.001), and median ICIQ-CLUTS was 12 (range 9-14) and 9 (range 5.7-12), (p < 0.001), before and after treatment, respectively. Median PinQ score decreased from 47.8 (range 38.9-59.7) to 39 (range 29-53.15) following treatment (p = 0.04). Median total SDQ score before and after treatment was 17 (range 13.5-21) and 15 (range 12-21), respectively (p = 0.939).

Conclusion: Parasacral TENS was associated with a significant improvement in urinary symptoms and QoL; however, there was no change in psychological symptoms, as measured using the SDQ.
