Classification

The condition is divided into two types: Primary Nocturnal Enuresis (PNE) and Secondary Nocturnal Enuresis.

Primary Enuresis

Primary enuresis occurs when a child is beyond the age at which bladder control would normally be anticipated and:

• Continues to average at least two wet nights a week with no long periods of dryness, or
• Would not sleep dry without being taken to the toilet by another person

Some medical definitions list Primary Nocturnal Enuresis (PNE) as a clinical condition at between 4-5 years old. This type of classification is frequently used by insurance companies. It defines PNE as “Persistent bedwetting in the absence of any urologic, medical or neurological anomaly in a child beyond the age when over 75% of children are normally dry.”[3]

Secondary Enuresis

Secondary enuresis occurs after a patient goes through an extended period of dryness at night (approx. 6 months or more) and then reverts to night-time wetting. Secondary enuresis can be caused by emotional stress or a medical condition, such as a bladder infection. [4]
