Thus, bladder pressure, sphincter activity, and flow rate are recorded simultaneously. This takes about an hour and a half. If the problem is detected before damage requires surgical correction, the child begins a simple retraining program that centers on urinating frequently, completely, and in a relaxed manner. This may require months or even years. The child goes to the bathroom at two-hour intervals, tries to maintain a continuous stream by remaining completely relaxed, and then tries to urinate again and again until unable to pass any more urine.
Secondary enuresis is bed-wetting in a child who has had bladder control.
These terms do not apply to wetting problems due to physical illness or anatomical defect. The APA definition includes daytime wetting not due to disease or defect. For every child with daytime wetting, it's reported there are six who wet at night. Typically, bed-wetting occurs during the first third of sleep. When it takes place in REM sleep, the child may remember dreaming about urinating.
