Snow A, et al. - Adenotonsillectomy (AT) for the treatment of pediatric obstructive sleep apnea (OSA) appears to improve nocturnal enuresis (NE) in this secondary analysis of a randomized clinical trial.

• Three hundred ninety-three of the 453 children enrolled were analyzed, with 201 of them being girls (51.1%).

• At baseline, the mean (SD) age was 6.54 (1.40) years.

• The number of children with NE in the AT and watchful-waiting groups was similar at the baseline.

• After 7 months, the probabilities of NE were about twice as high in the watchful-waiting group as in the AT group.

• There was a decrease in the number of children with NE (n = 38) after AT.

• At the follow-up, the prevalence of NE did not alter significantly in the watchful-waiting group (n = 66).

• Despite the fact that NE was less common in girls, other clinical characteristics such as age, race and ethnicity, obesity, and the apnea-hypopnea index were not associated with NE improvement.
