Coexistence of Upper Airway Obstruction and Primary and Secondary Enuresis Nocturna in Children and the Effect of Surgical Treatment for the Resolution of Enuresis Nocturna.

Objective. The aim of this study is to investigate the coexistence of upper airway obstruction (UAO) and primary enuresis nocturna (PEN) and secondary enuresis nocturna (SEN) in children. Besides, the efficacy of surgery on resolution of enuresis nocturna is evaluated. Materials and Methods. The children with PEN and SEN were included in the first group and investigated for UAO in the Department of Otorhinolaryngology. During the same period, children who had been planned for an operation to treat UAO over 5 years old were included in the second group and were evaluated in the Department of Urology for PEN and SEN before the operation. Results. A hundred patients completed the study (50 patients in Group 1, 50 patients in Group 2). According to the otolaryngologic examination, 20 of 25 PEN patients and 9 of 25 SEN patients also had UAO. The difference was statistically different (P < 0.05). The second group consisted of fifty patients on the surgery list for upper airway obstructive pathologies. Coexistence of PEN and SEN is found in 12 and 3 of children, respectively. These ratios were statistically significant (P < 0.05). The improvement rate of PEN and SEN after operation in the second group was 83.3% and 33.3%, respectively. The difference was statistically significant (P < 0.05). Conclusion. There is a strong relationship between PEN and UAO, but it cannot be declared for SEN patients. UAO should be kept in mind as a possible etiologic factor for PEN.
