Treatment Recommendations for Nocturnal Enuresis in a 6-Year-Old Male

For a 6-year-old male with bedwetting, the first-line treatment should be an enuresis alarm device, with desmopressin as a second-line therapy if the alarm is unsuccessful or not tolerated. 1

Initial Assessment

Before starting treatment, a basic evaluation should include:

• Urinalysis (dipstick test) to rule out diabetes mellitus or kidney disease 1
• Frequency-volume chart/bladder diary for 1-2 weeks to document:
  • Wet and dry nights
  • Daytime voiding patterns
  • Fluid intake
  • Any daytime symptoms 1
• Assessment for constipation (common comorbidity)
• Determination if monosymptomatic (bedwetting only) or non-monosymptomatic (with daytime symptoms)

Treatment Algorithm

Step 1: General Lifestyle Advice (First 1-3 months)

Start with these behavioral modifications:

• Regular voiding schedule (morning, at least twice during school, after school, dinner time, and bedtime) 1
• Fluid management:
  • Liberal fluid intake during morning/early afternoon
  • Minimize evening fluid intake (especially after dinner)
  • Avoid caffeinated beverages 1
• Treat constipation if present (polyethylene glycol is effective) 1
• Maintain a calendar of wet/dry nights (has therapeutic effect itself) 1
• Encourage physical activity 1
• Reassure family that bedwetting is not the child's fault and is common 1

Step 2: Alarm Therapy (If lifestyle changes insufficient after 3 months)

The enuresis alarm is the most effective long-term treatment:

• Success rate: approximately 66% become dry during treatment 2
• Nearly half remain dry after treatment completion 2
• Lower relapse rates than medication 2
• Requires commitment and support from parents
• Most effective for motivated families who can manage disrupted sleep

Step 3: Desmopressin (If alarm fails or isn't tolerated)

Consider desmopressin as second-line therapy:

• Approximately 30% of children are full responders, 40% partial responders 1
• More immediate effect than alarm but less long-term success 2
• Most effective for children with nocturnal polyuria (excessive nighttime urine production) 1
• Oral formulations preferred over nasal spray 1

Important safety considerations with desmopressin:

• Restrict fluid intake from 1 hour before until 8 hours after administration 3
• Monitor for hyponatremia (headache, nausea, vomiting, altered mental status) 3
• Contraindicated in patients with:
  • Excessive fluid intake
  • History of hyponatremia
  • Polydipsia 3

Step 4: Combination or Specialist Referral

For treatment-resistant cases:

• Consider combination therapy (alarm + desmopressin)
• Consider anticholinergic medication if there are signs of bladder dysfunction
• Refer to specialist (pediatric urologist or pediatric nephrologist)

Common Pitfalls to Avoid

1. Starting active treatment too early: Treatment should usually not begin before age 6 years 1

2. Punishing the child: This is counterproductive and harmful to the child's self-esteem 1

3. Waking the child to void: This only helps for that specific night and doesn't treat the underlying issue 1

4. Expecting immediate results: Basic bladder advice shows limited efficacy (18%) and takes up to 3 months to show effect 4

5. Neglecting constipation: Treating constipation can significantly improve enuresis outcomes 1

6. Excessive fluid restriction: While limiting evening fluids helps, excessive restriction is not recommended

7. Overuse of medications: Desmopressin has a low curative potential and should be used appropriately 1

Remember that nocturnal enuresis has a spontaneous resolution rate of about 14% per year 5, but treatment is warranted due to the significant impact on the child's self-esteem, interpersonal relationships, and school performance.
