Studies reveal nocturnal polyuria in some but not all children with enuresis. Although nocturnal polyuria is important in the pathophysiology of enuresis, overproduction of urine per se cannot be the sole causal factor. Nocturnal polyuria does not explain why children with enuresis do not wake up to the sensation of a full or contracting bladder or why enuresis can occur during daytime naps.
