Enuresis nocturna can be provoked in normal healthy children by increasing the nocturnal urine output

In a large proportion of enuretics, the enuresis episodes are accompanied by high urine output at night. At this study we provoked a high urine output in normal non-enuretic children in order to investigate whether volume provocation per se could cause enuresis.In six of ten children it was possible to provoke nine enuresis-like episodes. The enuresis volumes were small with no relation to functional bladder capacity. It is concluded, that increased urine output at night may produce enuresis-like episodes even in normal children.
