Effective Nocturnal Enuresis Treatments: From Motivational Therapy to Pharmacologic Interventions

Treatment of Nocturnal Enuresis in Children

General Approach
The primary approach to managing nocturnal enuresis in children emphasizes reassurance and supportive measures. It is crucial to reassure both the child and their parents that the condition is typically self-limited. Avoiding punitive measures is essential to prevent adverse effects on the child’s psychological development.

Lifestyle and Behavioral Modifications
– Fluid Management: Restrict fluid intake to 2 ounces after 6 or 7 PM. Ensure the child voids at bedtime.
– Dietary Considerations: Avoid extraneous sugar and caffeine after 5 PM.
– Addressing Snoring and Adenoids:If the child snores and has enlarged adenoids, a referral to an otolaryngologist should be considered, as adenoidectomy can sometimes resolve enuresis.

Age Considerations
– Children Under 6 Years: Active treatment is generally avoided as enuresis is very common in this age group.
– Older Children and Puberty:Treatment is more effective in children approaching puberty, particularly those motivated to stay dry.

Initial Measures
– Motivational Therapy: Use a star chart for dry nights. Waking the child a few hours after they fall asleep to void may help, though it is not a curative measure.
– Conditioning Therapy: This involves using an alarm that activates when voiding occurs, with a reported success rate of 30-60%. Persistence for several months may be necessary, and it is most effective in older children.
– Self-Hypnosis:Some children respond well to self-hypnosis, which can help them manage enuresis psychologically and improve nighttime voiding habits.

Pharmacologic Therapy
Pharmacologic interventions are second-line treatments and focus on managing symptoms rather than curing the condition.

– Desmopressin Acetate: This synthetic analog of antidiuretic hormone reduces nighttime urine production. It is available as an oral tablet (0.2-0.6 mg 2 hours before bedtime). Effective in about 40% of children, especially those nearing puberty. Fluid restriction at night is crucial, and the medication should not be used if the child has systemic illness or polydipsia. If effective, use for 3-6 months and then attempt dosage tapering.
– Anticholinergic Therapy: For therapy-resistant enuresis or overactive bladder symptoms, options include oxybutynin (5 mg) or tolterodine (2 mg) at bedtime. Dosages may be doubled if ineffective, with monitoring for constipation as a side effect.
– Imipramine: This tricyclic antidepressant, used as a third-line treatment, has mild anticholinergic and alpha-adrenergic effects, slightly reduces urine output, and may alter sleep patterns. Dosages are age-dependent: 25 mg for children aged 6-8 years, 50 mg for those aged 9-12 years, and 75 mg for teenagers. Side effects include anxiety, insomnia, dry mouth, and potential heart rhythm effects.

Combination Therapy
Combining different therapies often enhances effectiveness:
– Alarm Therapy + Desmopressin:More effective together than either alone.
– Oxybutynin + Desmopressin: Combining these can yield better results.
– Desmopressin + Imipramine:This combination can also be effective.

Persistent use and close monitoring are crucial in determining the success of these treatment
