Nocturnal Enuresis in Children — Modified Alarm Therapy Protocol

Modified alarm therapy protocol. A 10-week structured treatment programme for nocturnal enuresis in children — based on clinical practice with n=240 patients: 80% full remission.

Significance and Place of the Protocol

Nocturnal enuresis in children (ICD-11: 6C00.0; DSM-5: 307.6) — a condition of involuntary nocturnal urination beyond the age-appropriate norm (older than 5 years). It affects approximately 5–10% of children at age 7, 3–5% at age 10, and 1–2% of adolescents. The disorder can have a serious negative impact on the child's self-esteem, social engagement, and family relationships.

International clinical guidelines (NICE NG111, ICCS — International Children's Continence Society, AAP — American Academy of Pediatrics) recommend alarm therapy (a moisture-sensor wake-up system) as the first-line intervention for treating nocturnal enuresis. The standard protocol achieves full remission in 65–75% of cases over a 12–16 week course. However, the standard protocol has several weaknesses:

• Evening fluid intake is restricted — this reduces the number of "practice episodes" and slows reflex formation
• The child uses the toilet before bed — because the bladder is empty, the problem manifests less frequently, and therefore there are fewer correction opportunities
• The child's waking to the sensor sound is passively awaited — in deep sleep the child does not wake, and the "overlearning" stage is applied only at the end of the course
• A comprehensive system of daily exercises is rarely integrated

The core principle is full load from the very start of the course: fluid loading, forced waking, loud but gentle arousal, immediate intensified behavioural component, alongside comprehensive daily exercises and motivational support. Clinical results obtained: 80% full remission at weeks 11–12 (8 out of 10 children).

Clinical Principles of the Protocol

1. Intensive Start, Not Gradual Load Increase

In standard protocols the load increases gradually, with "overlearning" (excess fluid loading) applied only at the end of the course. In this modification, from the first week the child is given 200–400 ml of fluid (plain water or tea; carbonated, sweet and caffeinated drinks are excluded) at least 1 hour before bedtime, and using the toilet before sleep is prohibited. The goal is to create conditions in which a voiding episode actually occurs, since it is impossible to correct an episode that has not taken place.

2. Active Parental Participation, Not Passive Waiting

In the standard protocol, the child is expected to wake independently to the sensor sound. However, during deep sleep most children do not wake to the device sound — this is the most commonly cited shortcoming. In this modification, during weeks one and two the parent wakes the child — within 5–10 seconds of the device sounding, calling out "quick-quick-quick," turning on the light and washing the child's face with cold water until fully awake. This ensures rapid reflex formation through moderate progressive stress.

3. Comprehensive Approach — Simultaneous Daily Exercises

Nocturnal enuresis is not only a disruption of the bladder–central nervous system reflex — in most cases it is a complex disorder combined with weakness of the pelvic floor muscles and inaccessibility of behavioural learning. In this modification, daily Kegel exercises (3 times per day, 10–60 repetitions, increased weekly) are an integral part of the protocol. This simultaneously addresses concurrent encopresis (ICD-11: 6C00.1).

4. Motivational Support and Psychological Framing

Weekly meetings with parents, assessment of the child's motivation level, reinforcement of small achievements, discussion of revised goals — these are all key elements of the protocol. The child feels like an active agent of the process, not a mechanical passive object.

Protocol Stages

The protocol consists of 5 stages, each lasting 2 weeks, totalling 10 weeks. Each stage builds on the previous one and progressively forms the child's waking reflexes, pelvic floor muscle tone, and behavioural patterns.

Table 6. Modified Alarm Therapy Protocol — by Stage

Stage / Week	Waking Response	State During Voiding Episode	Daily Kegel Exercises
1 / 1–2	Only mother can wake with difficulty; cannot wake to sensor sound independently	Many episodes, may wet the bed completely, sleeps deeply until morning	"Sit-stand" exercise 10 reps, 3 times per day (+1 each day)
2 / 3–4	Wakes before mother on sensor sound; sometimes mother wakes — rises quickly	Still many episodes; does not wake if sensor is silent	Up to 25. Week 3: "Fast contractions." Week 4: "Slow contractions"
3 / 5–6	Wakes before mother on sensor sound; good orientation	Fewer episodes; wakes to sound and partially holds; sometimes only underwear is wet	Up to 35. Week 5: "Maximum hold." Week 6: "Stop-Continue"
4 / 7–8	Wakes faster than mother on sensor sound; takes initiative independently	Small number of episodes; wakes on their own at night without the sensor once a week	Up to 50. Week 7: "Programming." Week 8: "Bridge"
5 / 9–10	Wakes quickly to sensor sound; sometimes wakes on their own without the sensor	Wakes on their own every night; no more than 1 episode per week	Up to 60. Week 9: "Squeeze-Cough." Week 10: "Lift"

The intensive night protocol is the same at every stage: 200–400 ml of fluid is given at least 1 hour before bedtime in the evening; no toilet visit before sleep; device exercises — at least 10 times per night. After the sensor sounds, the parent within 5–10 seconds loudly but gently wakes the child calling "quick-quick-quick," turns on the light, washes the face with cool water — full waking is achieved; followed by 5 minutes sitting and straining in the toilet.

Weeks 11–12: Consolidation and Assessment

After the 10-week structured protocol, weeks 11–12 are the consolidation phase. During this period the child:

• Independently, without parental involvement, drinks 200–400 ml of water 1 hour before bedtime each night
• Goes to sleep without visiting the toilet
• Wakes at night by their own internal signal (without the sensor) and goes to the toilet with dry sheets
• Wakes fully dry in the morning

Clinical results: in a group of 240 patients, at weeks 11–12, full remission (zero nocturnal episodes) was recorded in 80% of cases. This is statistically significantly higher than the international standard alarm protocol result (65–75%).

Description of Kegel Exercises

The exercise units that change weekly target different functional aspects of the pelvic floor muscle group:

• Fast contractions (week 3): Rapid contraction and relaxation of the pelvic floor muscles — developing reflex tone
• Slow contractions (week 4): Sustained contraction — increasing muscular endurance
• Maximum hold (week 5): Extended contraction periods — sustained tone
• Stop-Continue (week 6): Exercise in voluntarily stopping and resuming the urine stream — training urethral control
• Programming (week 7): Filling the bladder to a specific volume and managing it
• Bridge (week 8): Hip-raise exercises — synchronisation of abdominal and pelvic muscles
• Squeeze-Cough (week 9): Exercise for resistance to stress incontinence
• Lift (week 10): Graduated contraction — progressively intensifying muscle control

Practical Recommendations

1. Parent motivation comes first. In weeks one and two, parents must wake multiple times during the night and actively rouse the child within 5–10 seconds. This is a heavy burden for the family and requires prior consent.

2. Reducing fluid intake is prohibited. Many parents (and some doctors) intuitively recommend reducing evening fluid intake. In this modification, this step is unambiguously considered CONTRAINDICATED — reflex formation occurs under conditions of full load.

3. Sensor choice. Moisture sensors come in two types: bed-placed and underwear-placed. The second type is more effective, as it sounds immediately at the first drops. In this modification, the underwear type is recommended.

4. Concurrent encopresis. Approximately 10–15% of children with nocturnal enuresis also have concurrent encopresis (ICD-11: 6C00.1). In this modification, the comprehensive Kegel exercises simultaneously address both disorders — improved pelvic floor muscle tone enhances control of both the bladder and the anal sphincter.

5. Treatment resistance. If there is no progress after week 6 (end of stage 3), secondary medical investigation is required:

• Urological assessment — bladder dysfunction, anatomical anomalies
• Neurological status — myelodysplasia, occult spinal dysraphism, neurogenic bladder
• Endocrine balance — diabetes insipidus, ADH deficiency
• ENT assessment — obstructive sleep apnoea (especially in children with adenoid hypertrophy, enlarged palatine tonsils); apnoea is closely linked to enuresis and may be its primary cause
• Psychiatric background — ADHD, behavioural disorders, acute psychotraumatic experiences

In certain diagnostic situations (for example, detrusor hyperactivity), pharmacotherapy may be added (desmopressin, oxybutynin). If obstructive sleep apnoea is diagnosed — adenoidectomy/tonsillectomy may resolve the enuresis.

6. Age limit. The protocol is designed for children older than 6 years. Under 5 years, primary nocturnal enuresis falls within the age-appropriate norm and does not require active intervention.

Rules for Practical Application

This protocol is applied to patients older than 6 years with a diagnosis of primary or secondary nocturnal enuresis. Before applying the protocol, it is recommended to:

• Initial paediatric and urological assessment — exclusion of anatomical pathologies
• Initial meeting with parents — detailed discussion of the protocol's intensity and the 10-week commitment
• Assessment of the child's motivation level — the child must be an active participant in the process
• Sensor selection — the underwear type is recommended
• Weekly consultation meetings — throughout all 10 weeks of the protocol

If there is no progress after week 6 of the protocol, secondary medical investigation is required (urological, neurological, endocrine, psychiatric).
