Initial Management of Nocturnal Enuresis

Introduction to Nocturnal Enuresis

The American Academy of Child and Adolescent Psychiatry recommends reassurance that the family history confirms a genetic basis, with a 44% risk when one parent had enuresis and a 77% risk when both parents were affected, before implementing behavioral modifications and completing a frequency-volume chart to guide treatment 1

The American Urological Association suggests performing a urine dipstick test to exclude diabetes mellitus and kidney disease, with urgent blood glucose testing if glycosuria is present 4
The International Children's Continence Society recommends assessing and aggressively treating constipation first, as it is a paramount cause of treatment resistance, with polyethylene glycol as a stool softener (Grade Ia evidence) 4

The American Academy of Pediatrics recommends having the family complete a frequency-volume chart for at least 2 days of measured fluid intake and voided volumes, plus 1 week of documenting wet/dry nights, daytime incontinence, and bowel movements, to objectively detect nocturnal polyuria and identify polydipsia 4
The European Society for Pediatric Urology suggests weighing nighttime diapers to assess nocturnal urine production, as nocturnal polyuria indicates desmopressin would likely be successful 4

The American Urological Association recommends implementing evidence-based lifestyle changes, including regular daytime voiding, restricting evening fluid and solute intake, encouraging physical activity, keeping a calendar of dry and wet nights, and informing parents that waking the child at night to void is allowed but only helps for that specific night, if at all (Grade IV evidence) 4

The American Academy of Pediatrics recommends not starting active treatment before age 6 years, though general lifestyle advice should be given to all bedwetting children, with enuresis alarm therapy as first-line for monosymptomatic enuresis in children aged 6-7+ years, and desmopressin as an alternative when rapid onset or short-term improvement is the priority 4, 5
The International Children's Continence Society suggests desmopressin dosing of 0.2-0.4 mg tablets or 120-240 µg melt formulation, with critical safety warning to restrict fluid intake from 1 hour before the dose until 8 hours after to avoid water intoxication, hyponatremia, and convulsions (Grade Ia evidence) 5

The American Academy of Pediatrics recommends scheduling monthly follow-up appointments to sustain motivation and assess response, with an individualized program with realistic goals between visits improving outcomes 4, 5
The American Urological Association suggests continuing treatment for at least 2-3 months before declaring failure 5

The International Children's Continence Society recommends avoiding failing to screen for and treat constipation, punitive parental responses, inadequate alarm monitoring, excessive fluid intake on desmopressin, and missing non-monosymptomatic enuresis, which requires treating underlying bladder dysfunction first 2, 5
