Comparative Study of the Efficacy of TENS Versus Placebo in Isolated Primary Enuresis

Plain-language summary

Nocturnal enuresis is a functional urinary disorder in children. It is intermittent urinary incontinence during sleep in children aged 5 years and older. It is said to be "primary" if the child has never been clean at night for at least 6 months and "isolated" if there are no other associated urinary symptoms, including daytime symptoms. It is a common condition with significant repercussions, including disruption of family and social life and a frequent decline in self-esteem. Without treatment, it can persist into adulthood. All these reasons justify taking care of these children. This is usually based on: The establishment of hygienic-dietetic rules: Regular urination and before sleeping, limitation of fluid intake in the evening. They are systematically implemented, whatever the subsequent management Drug treatments (Desmopressin, oxybutynin). These treatments have an efficiency of 60 to 70% at 6 months post treatment and sometimes have side effects. Non-drug treatments: Night-time "pee stop" alarms. They have an efficiency of around 70%. They are little used because they often wake up the whole family and are not reimbursed by social security. TENS (Transcutaneous Electro Neuro Stimulation) is a neuro-modulation technique which consists of stimulating the nerves by means of skin electrodes in order to obtain a somatic response. In urology, it is mainly used by stimulating either the sacral region, origin of the vesical innervation, or the tibial nerve. Its main indication is overactive bladder, a source of discomfort and incontinence. It is used at home, the side effects are exceptional and it does not disturb the activities of the patients. Few studies have evaluated its effectiveness in isolated primary enuresis.
