Few things are more distressing to a family than having a child who is continuously wet.
The child suffers the ridicule of his classmates, the odors are offensive, the laundry mounts, and the parents agonize over their helplessness in bringing an end to the seemingly intractable problem. The family can only take comfort from the realization that the problem is common and that children generally outgrow it. In the meantime, however, the agony continues and there exists a small subgroup of these children who actually damage their urinary tract in the process. So, there are legitimate reasons to want to get to the bottom of this and bring it under control quickly. Primary enuresis is seen in children, who have never had a period of being totally toilet trained, whereas secondary enuresis occurs after a period of being dry for at least 6 to 12 months.
