US-measured bladder wall was thickened. After 6 months of antimuscarinic treatment, we re-assessed the children with US and UD; the relation between UD and US measurements was confirmed. After analysing these data, we considered the use of a new diagnostic assessment for patients with NMPNE. In children with a significant US measurement, i.e. a bladder wall with a thickness of > 3 mm (full bladder) and > 5 mm (empty bladder), the diagnostic assessment was concluded and therapy was started. We restricted the UD examination exclusively to those patients who either had severe intractable symptoms or did not respond to treatment. This new management was applied to 453 patients with NMPNE. After the first 6 months of therapy all the patients were assessed with a new US study. RESULTSIn all, 343 patients (75.7%) were fullresponders, with a normal bladder wall thickness; 82 (18.1%) were partial responders but with no normalization of bladder wall thickness; only 28 (6.2%) were classified as nonresponders with a persistent thickened bladder wall.

These findings enabled a close connection between nocturia in adulthood and enuresis in childhood to be hypothesized. Furthermore, this analysis provided evidence of the link between suffering from nocturia, and previously from enuresis, and having children affected by enuresis.
