Some children have only one or the other, while other children have both diurnal and nocturnal enuresis. Another word that is sometimes used to describe urinary leakage is incontinence.
Enuresis occurs for a number of reasons.
This, however, is a rather infrequent cause of enuresis. Often times we do not know the exact reason that wetting occurs. There are many theories that have been proposed as causes for wetting, particularly in patients with nocturnal enuresis. When it starts rather suddenly in a child who previously has had no problems with wetting, enuresis can be the first sign of a urinary tract infection . This deserves prompt investigation by his or her primary doctor.
