Current trends, diagnosis, and treatment of enuresis.

This survey describes the evolution of our concept of monosymptomatic bedwetting over the last decades. It takes you briefly through psychology and enuresis. The minor role of bladder pathology is described ending up with focusing on the mismatch between bladder capacity at night-time and urine production. Monosymptomatic bedwetting should currently be regarded as an umbrella diagnosis allocated to children where daytime urinary problems have been excluded. Within the diagnosis of monosymptomatic bedwetting we can nowadays identify at least two groups. One is related to children who have a large night-time urine production and a normal bladder capacity, and the other is related to children who have a large night-time production, but a bladder capacity too small for the normal urine production. The genetic aspects are currently investigated. The results and this kind of research will probably end up in a further subgrouping.
