Parasacral transcutaneous electrical neural stimulation versus?urotherapy in primary monosymptomatic enuresis: A prospective randomized clinical trial

摘要

Abstract Objective To evaluate the clinical response of parasacral transcutaneous electrical neural stimulation (parasacral TENS) associated with urotherapy in children with primary monosymptomatic nocturnal enuresis?(PMNE) compared to urotherapy alone. Material and Methods This prospective controlled clinical trial enrolled 72 children over 5 years of age with PMNE. Children were randomly divided into two?groups, control group (CG), treated with urotherapy and scapular stimulation, and experimental group (EG), treated with urotherapy and parasacral TENS. In both groups, 20 sessions were performed, 3 times weekly, for 20?min each, with 10?Hz frequency, 700?μS pulse width and intesity determinated by the patient threshold. The percentages of dry nights were analyzed for 14 days before treatment (T0), after the 20th session (T1), 15 (T2), 30 (T3), 60 (T4), and 90 (T5) days after the end of the sessions. Patients of both groups were followed with intervals of 2 weeks in the first month and monthly for three?consecutive months. Results Twenty‐eight enuretic children, 14 girls (50) with a mean age of 9.09?±?2.23 years completed the study. There was no difference in mean age between groups. Mean percentage of dry nights in EG at T0 was 36, at T1 49, at T2 54, at T3 54, at T4 54, and 57 at T5; while in CG, these percentages were 28, 39, 37, 35, 36, and 36, respectively. Conclusions Parasacral TENS associated with urotherapy improves the percentage of dry nights in children with PMNE, although no patient had complete resolution of symptoms in this study.
