Transcript of Enuresis

Management History Definitions 3 System Model Enuresis Dr K Balasubramanian
Paediatric Consultant
Maidstone Hospital
Any type of wetting episode that occurs in discrete amount during sleep in a child >5 years of age.

Long standing no bladder control attained

Had a dry period at night for at least 6 months

Only have enuresis as a single symptom

Have additional lower urinary tract symptoms +/- bladder dysfunction
Enuresis Primary Secondary Monosymptomatic Non-monosymptomatic Epidemiology Why? Nocturnal polyuria
Urine production normally falls at night to <50% of daytime levels

Definition: >130% of expected bladder capacity

EBC 2-12 yrs:
(age in years x 30) + 30 ml
Lack of arousal
Fundamental problem for all

Not because of deep sleep

Can occur at any stage of sleep

Disorder of brainstem arousal
Reduced bladder capacity
Overactive bladder
Constitutionally small bladders

< 65% of EBC

Spontaneous involuntary detrusor contraction during filling/ storage phase

Lower urinary tract symptoms +

Infections – UTI
Metabolic -DI / DM ,hypercalciuria
Ectopic ureter, Neurogenic bladder
Obstructive uropathy
Other causes Enuresis profile Severity
Primary / Secondary

Child ever wakes to stimuli?

Early wetting, large amount, more than once

Single void, late at night, dry if sleeps shorter

Daytime symptoms – urgency, frequency
Wets more than once at night, small amounts
Wakes up after wetting

Lack of arousal Polyuria Small Bladder / Arousal Overactive bladder Symptoms of bladder dysfunction Complications Difficulty to initiate void
Stop-start stream
Abdominal straining
Need to sit to void in boys
Discomfort Known renal tract anomalies
Recurrent UTI
Constipation +/- soiling
OSA /Sickle cell disease Neuro Developmental issues Motor disorder
Learning difficulties
Child & Family
factors Child's motivation
Child's drinking / voiding patterns
Bedtime routines
Sleeping arrangements
Family h/o enuresis
? NAI What is it? Examination &
Investigations BP
Abdomen: bladder/ faecal mass
