Definition: The word enuresis is derived from a Greek word mean ing to make water. The term is used to refer to wetting by night or day, and night-time wetting is referred to as nocturnal enuresis (NE). NE can be divided into primary nocturnal enuresis (PNE) and secondary nocturnal enuresis (SNE) forms. If the child has experienced a minimum 6-month period of continence before the onset of the bed-wetting, the NE is considered SNE. With PNE, psychological problems are almost always associated, although rarely the cause. In contrast, psychological problems are a possible cause of SNE. The co morbidity of behavioural problems is 2-4 times higher for children with NE in all epidemiologic studies. The emotional impact of NE on a child and family can be considerable. Child ren with NE are commonly punished and are at significant risk of emotional and physical abuse. Numerous studies report feelings of embarrassment and anxiety; loss of self-esteem; and effects on self-perception, interpersonal relationships, quality of life, and school performance. A significant negative impact on self-esteem is reported even in children with enuretic episodes as infrequent as once per month.
