In the UK approximately half a million children aged between 5 and 16 wet the bed but the percentage of children decreases with age. Whilst most children will be dry in the day by the age of 5 years, 1 in 75 children older than five will have some degree of day time wetting.įor all children, night time bladder control takes longer to develop than day time control but again, the age at which children gain night time dryness also varies greatly. The age at which children gain brain control over their bladders varies and so children differ greatly in how long it takes them to become fully toilet trained. As we get older we start to learn to block this reflex our brains learn that we can control when the bladder contracts and also stop it from contracting and so we become ‘potty trained’. When we are babies our bladders fill and empty without our control as a reflex when the bladder is full. What is considered normal depends on your child’s age. Relaxing one hand whilst squeezing with the other takes coordination and this is what the sphincter and detrusor muscles should do when you urinate (‘wee’) the sphincter relaxes at the same time that the detrusor bladder muscle contracts. The best way to empty the balloon of water is to relax your fingers holding the neck of the balloon and at the same time, squeeze down with the hand around the balloon itself. Your other hand rests on and around the balloon just like the detrusor muscle. To help understand how the bladder works, imagine you are holding a balloon filled with water your fingers on one hand hold the neck of the balloon shut and so are acting like the sphincter muscle. The bladder increases in size as your child grows and so, gets an increased capacity and therefore, older children can hold more urine and void less regularly than young children who, because their bladders can hold less, need to void more frequently. The bladder should stretch easily as it fills with urine and should not contract or get increased pressure inside as it fills. ![]() The bladder is like a balloon inside your body that fills up with, and stores, urine. ![]() Cochrane Database Syst Rev.The important muscles that relate to the bladder are firstly the ‘detrusor muscles’ in the bladder wall and secondly the ‘sphincter’ which is a ring of muscle at the junction of the bladder and urethra which stops urine leaking out between voids (wees). Simple behavioural and physical interventions for nocturnal enuresis in children. The standardization of terminology of lower urinary tract function in children and adolescents: report from the Standardisation Committee of the International Children's Continence Society. NICE (October 2010).Nocturnal enuresis - The management of bedwetting in children and young people.Jarvelin et al found that structural abnormalities and functional disorders of the urinary tract (such as unstable bladder contractions or urinary tract infections) was more often seen in children with day time wetting than in children who had night- time wetting alone (4).the symptom of bedwetting is termed as enuresis or intermittent nocturnal incontinence regardless of whether concurrent daytime symptoms are present or not (3)ĭay time wetting is rare but is considered to be a significant problem and investigations should be carried out to identify any physical (organic) causes such as urinary tract dysfunction, congenital malformation and neurogenic disorders (4).enuresis can be termed nocturnal enuresis to add greater clarity when needed. ![]() The International Children’s Continence Society (ICCS) which uses the term “incontinence” when describing uncontrollable leakage of urine defines enuresis as incontinence in discrete episodes while asleep in children who are at least 5 years or older.The Diagnostic & Statistical Manual of Mental Disorders (DSM- IV) defines nocturnal enuresis as an involuntary voiding of urine during sleep, present at least twice a week, in children aged more than 5 years without any congenital or acquired defects of the central nervous system (2).The terminology used to describe nighttime wetting has been the subject of much confusion with the terms nocturnal enuresis, enuresis, bedwetting and incontinence of urine when sleeping being used synonymously (2). It may be nocturnal, during the day - or both (1). Enuresis is uncontrolled or involuntary discharge of urine in a child, 5 years or older in the absence of a physical disease.
