Abstract
We assessed the efficacy of voiding and bladder biofeedback for achieving perineal synergy and curing symptoms in children with detrusor-sphincter dyssynergia A total of 16 boys and 27 girls 4 to 14 years old with detrusor-sphincter dyssynergia diagnosed by uroflowmetry and electromyography underwent biweekly voiding biofeedback therapy consisting of perineal floor electromyography during uroflowmetry. The 6 patients with enuresis and an unstable bladder also underwent bladder biofeedback training during cystometry. Biofeedback continued until detrusor-sphincter dyssynergia resolved. Followup consisted of electromyography and uroflowmetry 1 month after completing biofeedback training, and telephone interviews after 2 and 4 years. Biofeedback resolved detrusor-sphincter dyssynergia in all children, although the condition disappeared significantly sooner in girls (p <0.02). Secondary enuresis disappeared significantly earlier than primary enuresis (p <0.0001). The 2-year success rate of 87.18% for enuresis decreased to 80% at the 4-year followup. Voiding and bladder biofeedback achieves perineal synergy and cures symptoms in children with detrusor-sphincter dyssynergia
