Types of enuresis

Most children achieve day and nighttime continence by three or four years of age.

Nocturnal enuresis can be

• primary - the child has never achieved continence
• secondary - the child was dry for at least 6 months before wetting restarted (1).

Enuresis can also be divided into

• monosymptomatic - occurs in the absence of any daytime voiding symptoms, such as frequency, urgency, or incontinence
• nonmonosymptomatic - more common; a detailed history will elicit at least subtle daytime symptoms in the majority of children (2).
