Kim, Kim, Namgoong, Park, Park, Lee, Lee, Chung, and The Korean Enuresis Association: A Multicenter Prospective Study of the Effect of Imipramine and Desmopressin on Arousability in Children with Nocturnal Enuresis

Abstract

Purpose

We performed a multicenter, prospective study to evaluate the efficacy of imipramine and desmopressin to improve arousability and prevent nocturnal enuresis (NE).

Materials and Methods

The total of 48 children with NE were given questionnaires that included a scoring system for the assessing arousal from sleep. They were assigned into two groups: group 1 (imipramine 25 mg, 3 girls and 16 boys, mean age 7.9 years), group 2 (desmopressin 0.2 mg, 9 girls and 9 boys, mean age 7.5 years). The assessment of arousability was repeated 2 weeks and 4 weeks after medication. Eleven children were excluded because of incomplete data.

Results

Mean wetting events in group 1 decreased from 8.8 to 5.1 times (2 weeks) and 3.0 times (4 weeks) (p=0.009) versus 10.2 to 5.5 times (2 weeks) and 6.4 times (4 weeks) (p=0.007) for group 2. The mean threshold of arousability in group 1 was 4.9 (baseline), 4.4 (2 weeks), and 3.7 (4 weeks), and, for group 2, 5.1 (baseline), 4.8 (2 weeks), and 4.8 (4 weeks). The two groups were not different (p=0.14, p=0.73).

Conclusions

Imipramine and desmopressin, which are commonly used in treating NE in Korea, influenced wetting events but not arousability.
