Effectiveness of adenotonsillectomy in resolution of enuresis in children with sleep-disordered breathing: a hospital based prospective cohort study in Dar es Salaam, Tanzania

ABSTRACT 

Background: Adenotonsillar hypertrophy remains to be the commonest causes of sleep disordered breathing in paediatric patients and has been implicated as a cause of primary and secondary enuresis. The aim of this study was to determine the effectiveness of adenotonsillectomy in resolution of enuresis in children with sleep-disordered breathing.  

Methods: A hospital based prospective cohort study was conducted at Ekenywa Specialised Hospital in Dar es Salaam, from May 2018 to February 2019. Two hundred children aged 3 to 15 years with obstructive adenotonsillar hypertrophy who were admitted ready to undergo adenotonsillectomy were evaluated. Upon such evaluation, the primary outcome was the number of bedwetting incidents (nocturnal enuresis) post-operatively compared with preoperative incidents. Patients were kept under follow-up for 3 months. Data were collected using structured questionnaires regarding number of bedwetting incidents, type of enuresis (primary or secondary) and family history of enuresis. Data was analyzed using SPSS version 21 and p-values
