AB Background: Children with nocturnal enuresis (NE) are believed to have deep sleep with high arousal threshold. Studies suggested that obstructive sleep apnoea-hypopnoea syndrome (OSAHS) and NE are common problems during childhood. We sought to asses the prevalence of OSAHS in children with refractory nocturnal enuresis and whether its severity is associated with the frequency of bedwetting. MATERIALS AND METHODS: The study group comprised 43 children, aged 6-17 years, with refractory monosymptomatic NE and the control group 30 children, aged 5-17 years. All subjects underwent thorough neurological examination, single night polysomnography but only for patient group; a lumbosacral plain X-ray was done to exclude spina bifida. RESULTS: The groups were well matched. Two subjects of the control group had mild OSAHS. The mean age of the patients was (10±3 years), thirty one were boys and sixty seven percent showed frequent NE (>3 days bedwetting/week). Patients with NE had significantly higher rates of OSAHS (P < 0.0001); three patients had mild, 12 moderate and 11 showed severe OSAHS. There was no significant statistical difference among patients having OSAHS in relation to age, sex or family history of NE. The frequency of bedwetting was statistically significantly higher in patients with OSAHS (p=0.003). CONCLUSIONS: Patients with refractory NE had a significantly higher prevalence of OSAHS with no gender difference. The frequency of bedwetting was higher in patients with severe OSAHS.
