Nocturnal enuresis means involuntary bedwetting during sleep in a child aged 5 years or older.
  • Primary: the child has never been dry at night for at least 6 months.
  • Secondary: bedwetting returns after at least 6 months of dryness. This needs assessment for a new medical, urinary, bowel, sleep, or emotional cause.
It is common, often runs in families, and is not the child's fault or usually caused by poor parenting. Many children improve naturally with age. Textbook of Family Medicine, p. 1193.

What to check

A clinician will usually ask about:
  • Daytime urgency, frequency, wetting, painful urination, weak stream
  • Constipation or stool soiling
  • Excessive thirst or urine production
  • Snoring, disrupted sleep, or daytime sleepiness
  • New stressors, developmental history, medicines, and a family history
For uncomplicated primary bedwetting, history, examination, and urinalysis are often sufficient; imaging is usually unnecessary when these are normal. Textbook of Family Medicine, p. 1193.

Management

  1. Reassurance and practical measures
    • Do not punish or shame the child.
    • Regular daytime drinking and regular toilet visits.
    • Treat constipation if present.
    • Toilet immediately before bed.
    • Avoid large drinks close to bedtime, but do not excessively restrict daytime fluids.
    • Use mattress protection and involve the child positively in changing bedding if age-appropriate.
  2. Bedwetting alarm
    • Usually the best first option when the child and family can use it consistently for several weeks.
    • It has the best chance of a sustained response, though it requires support and persistence. Textbook of Family Medicine, p. 1193.
  3. Desmopressin
    • Can reduce wet nights quickly, useful for short-term situations such as camps or sleepovers, or when an alarm is unsuitable.
    • Relapse after stopping is common.
    • Must be prescribed with strict advice to limit fluid intake around the dose because excess water intake can rarely cause dangerously low sodium. The NICE bedwetting guideline supports individualized treatment choices.
  4. Other medicines
    • Anticholinergics or tricyclic antidepressants are not routine first choices and should be managed by an experienced clinician due to risks and specific indications.

Seek medical assessment promptly if

  • Bedwetting starts suddenly after prior nighttime dryness
  • Daytime wetting, recurrent urinary infections, pain/burning, abnormal stream, or blood in urine
  • Marked thirst, weight loss, fatigue, or large urine volumes
  • Constipation/soiling, gait weakness, back abnormality, or leg numbness
  • Loud snoring or witnessed pauses in breathing
  • Significant distress, bullying, or family strain
