Management of Nocturnal Enuresis with Daytime Frequency in a 10-Year-Old Female

For a 10-year-old female with nocturnal enuresis and daytime urinary frequency who has never achieved bladder control, a comprehensive treatment approach including behavioral therapy, alarm systems, and potentially medication is required.

Initial Assessment

• A thorough evaluation should include a frequency-volume chart to document voiding patterns and identify potential causes of the symptoms 1, 2
• Urinalysis is mandatory to rule out infection, diabetes, or kidney disease 1, 2
• Physical examination should focus on the lower back and external genitalia to rule out neurological or anatomical abnormalities 1
• Assessment for constipation is crucial as it can significantly contribute to both nocturnal enuresis and daytime frequency 3

Primary Treatment Approach

Behavioral Modifications (First-line)

• Implement a regular daytime voiding schedule (every 2-3 hours) to improve bladder function 1, 2
• Establish proper voiding posture with relaxed pelvic floor muscles during urination 1
• Maintain a voiding diary or calendar of dry and wet nights to track progress 1, 2
• Restrict evening fluid intake while ensuring adequate hydration earlier in the day 1, 2
• Ensure the child voids immediately before bedtime 1

Address Constipation (If Present)

• Treat constipation aggressively as it can lead to resolution of urinary symptoms in up to 89% of cases with daytime incontinence and 63% with nocturnal incontinence 3
• Use polyethylene glycol as a stool softener to optimize bowel emptying 1
• Aim for soft bowel movements daily, preferably after breakfast 1

Secondary Treatment Options

Enuresis Alarm (Most Effective Long-term)

• Implement a bedwetting alarm system as it has shown superior long-term success rates (66% initial success with more than half experiencing long-term success) 1, 2
• Recent research shows alarm therapy is significantly more effective than basic bladder advice alone 4
• Provide written instructions, establish a contract, and schedule frequent monitoring appointments (at least every 3 weeks) to enhance success 1

Pharmacological Options

For Nocturnal Enuresis:

• Desmopressin can be used, particularly in children with nocturnal polyuria, with approximately 30% full response rate 2
• Consider desmopressin for short-term use (e.g., sleepovers, camps) even if using other treatments 1
• Monitor for water intoxication, especially during intercurrent illness 1

For Daytime Frequency:

• If daytime symptoms persist and suggest detrusor overactivity, consider anticholinergic medication such as oxybutynin 1, 5
• Oxybutynin is FDA-approved for bladder instability in children 5 years and older 5
• Start with lower doses in children and monitor for side effects 5

Combination Approaches for Resistant Cases

• For children not responding to single modalities, consider combining alarm therapy with desmopressin 2
• In cases with mixed disorders (pelvic floor dysfunction and overactive bladder), a combination of urotherapy and medication may be necessary 1
• If constipation and urinary symptoms coexist, prioritize treating constipation first before escalating urinary treatments 3

Follow-up and Monitoring

• Schedule monthly follow-up appointments to sustain motivation and assess treatment response 2
• Continue treatment for at least 2-3 months before attempting to wean 2
• If no improvement occurs after 1-2 months of consistent therapy, reassess the diagnosis and consider referral to a specialist 2

Common Pitfalls to Avoid

• Failing to screen for and treat constipation, which is a common comorbidity 3
• Discontinuing treatment too early before establishing long-term success 2
• Using desmopressin without proper fluid restriction in the evening 2
• Punishing the child for wet episodes, which can worsen psychological impact 1
• Assuming basic bladder advice alone will be sufficient without adding more effective interventions like alarm therapy 4
