A Study of Oral Desmopressin in Previously Untreated Children Aged 5 to 15 Years With Primary Nocturnal Enuresis

An Open Label, Multi-national Study of Oral Desmopressin in Previously Untreated Children Aged 5 to 15 Years With Primary Nocturnal Enuresis

To evaluate the overall response to desmopressin treatment among previously untreated enuretic children aged 5-15 years after 3 and 6 months of treatment.

To investigate the influence of possible predictive factors on response after 3 and 6 months of treatment.

To evaluate the proportion of patients achieving dryness. To evaluate the long-term safety profile of oral desmopressin in children with primary nocturnal enuresis.
