The effect of adenotonsillectomy on pediatric nocturnal enuresis: a prospective cohort study.

Results: Of 420 children admitted for adenotonsillectomy, 97 had a positive history of preoperative enuresis, including 42 girls and 55 boys, with mean age of 48 months. The parents of 84 (86.6%) children agreed to participate in the study. Three months after adenotonsillectomy, enuresis had resolved completely in 51 (60.7%) children and had shown relative improvement in 22 (26.2%) children. Enuresis had not improved in the remaining 11 (13.1%) children (P<0.001). Conclusion: The results of this study indicate that adenotonsillectomy can improve enuresis in the majority of children with adenotonsillar hypertrophy. However, further evidence based on large multi-center randomized clinical trials is required to confirm these results.
