Daytime Incontinence in Children
Dr Steven McTaggart
Queensland Child & Adolescent Renal Service
Royal Children’s and Mater Children’s Hospitals
Brisbane.
Paediatric Society of Queensland Meeting
Friday 12 October, 2012
Children rated wetting themselves at school as the third most catastrophic event behind losing a parent and going blind.
Ollendick et al, Behav Res Therapy, 1989.
?A Mental Illness
Enuresis – DSM V
• Repeated voiding of urine into bed or clothes (whether involuntary or intentional).
• The behaviour is clinically significant as manifested by either a frequency of twice
a week for at least 3 consecutive months or the presence of clinically
significant distress or impairment in social, academic (occupational), or other
important areas of functioning.
• Chronological age is at least 5 years (or equivalent developmental level).
• The behaviour is not due exclusively to the direct physiological effect of a
substance (e.g., a diuretic or an antipsychotic medication) or another medical
condition (e.g., diabetes, spina bifida, a seizure disorder).

Case Study
• 10 year old girl - Referred from GE Clinic
› Long-standing patient of regional paediatrician
› Chronic constipation
multiple investigations and treatment incl 4
previous admissions for washout
› Daytime incontinence and nocturnal enuresis
Evaluation - History
• Age and pattern of toilet training
› longest dry periods - primary vs secondary
Toilet trained 2 years age
Dry during day for 2 months - never been dry since then
Wets daily – never dry at night
• Current symptoms and signs
› voiding pattern - stream/volume/frequency/post-void dribbling
Wears pad during the day – always damp but rarely soaks
through to clothes
Frequent voiding – up to 8x/day at school – ?small vols
No post-void dribbling
Not continuously wet
→ Consider Voiding Diary
Voiding Diary(http://childrenshospital.org/clinicalservices/Site2852/Documents/voidind_diary.pdf)
Voiding Diary App
Ectopic Ureter
Evaluation - History
› urgency / holding manoeuvres
› perineal hygiene - vulvovaginitis/balanitis
› dysuria / frequency / UTI’s
Previously recurrent UTI – none for 3 years
Evaluation - History
› CONSTIPATION
Constipation with soiling since 2 years age
Multiple unsuccessful treatments
Does not use school toilets
‘withholding’ behaviour
• Family history of urological problems
Nil
• Developmental / behavioural issues
• Social history - think about CSA
Evaluation - Physical Exam
• Exclude structural lesions› Abdominal examination
› Genital examination
labial adhesions/meatal stenosis
bifid clitoris
• Exclude occult neurological disorders› examine back for signs of occult spina bifida
› DTR’s lower limbs
› gait
› ?anal wink
Evaluation - Investigations
• Urinalysis - dipstick, M/C/S, (urine osmolality)
• Ultrasound
› estimate functional bladder capacity & residual
• IVP/CT urogram if suspect ectopic ureter
• MCU
› if abnormal USS esp trabeculation/thickened bladder wall
• Spinal imaging – not routine
• Urodynamics – not routine
Evaluation - Role of Spinal Imaging
Wraige E & Borzyskowski M, Arch Dis Child, 2002
retrospective study - 48 children with voiding dysfunction
closed spina bifida present in 5 patients - only 1 had no cutaneous,
neuro-orthopaedic or lumbosacral spine abnormalities.
Nejat et al, Pediatr 2008
176 children with encoporesis/enuresis - 88 with SBO and 88 control
17 (38%) bony spina bifida occulta
10/48 underwent MRI - 1 had lipoma requiring resection
Recommendations for Spinal Imaging
• neurological /neuro-orthopaedic abnormality
• secondary enuresis or deterioration in primary enuresis
• significant associated bowel abnormality
• urodynamic study suggesting neurogenic bladder
Evaluation - Urodynamic Studies
• Not required for majority of children
• Indicated if;› evidence of/at risk of upper tract deterioration
hydroureteronephrosis
high grade VUR
recurrent episodes of pyelonephritis
› suspicion or evidence of neurological abnormality
› ?significant daytime enuresis that fails to respond to
conventional treatment
› (unexplained secondary enuresis - cystoscopy is preferable)
Diagnosis – Functional Voiding Disorders
Voiding
postponement /
“holding”
Underactive bladder
Urge syndrome
Stress Incontinence
Dysfunctional voiding
Extreme Daytime
Frequency
General Principles of Treatment
Urotherapy
Pharmacological
Management
• Urotherapy
› Timed voiding, posture, avoiding holding
› Lifestyle – fluid intake
› Biofeedback / physiotherapy
• Pharmacological
› Anticholinergics
oxybutinin tabs / patches (Ditropan™)
tolteridine (Detrusitol™)
solenifacin (Vesicare™)
› (Tricyclic antidepressants)
› ? prazosin / ? ddAVP (Minirin™)
Bladder Retraining
“Bad” bladder behaviour
Imbalance in “inhibiting” and “initiating” voiding

Long Term Outcome
Kuh et al, 1999.› Longitudinal study of 1333 women with urinary incontinence (mean
age 48 years)
› 50% reported stress incontinence
› 22% reported urge incontinence
› 8% had severe symptoms
› Women who had daytime wetting as a child were more
likely to have severe symptoms
