Lehmann KJ, et al. - This study entails an analysis of relevant literature for the efficacy of adenotonsillectomy (T&A) in treating children aged 2–19 years with primary nocturnal enuresis (PNE). The evidence demonstrated that T&A caused improvement in more than 60% of patients, with complete resolution rates in excess of 50%. Persistent results were provided by meta-analysis focused only on studies including older patients (≥5 years) and those with short follow-up after surgery (≤3 months), suggesting a higher cure rate than would be expected based on natural history alone.
