When do children usually gain bowel and bladder control? Toilet Training
4 years Majority have bowel control 4 ½ years 79% dry 5+ nights a week 8% frequently bedwetting 5 yearsMajority have bladder control 9 ½ years 92% dry 5+ nights a week 1.5% frequently bedwetting Toilet Training
Nocturnal Enuresis
Involuntary wetting during sleep Without underlying pathophysiology May be associated with; Excessive nocturnal urine production Poor sleep arousal Reduced bladder capacity Nocturnal Enuresis
What are the risk factors? Nocturnal Enuresis
Risk factors include; Family history Daytime wetting and encopresis Developmental delay Constipation Excess methylxanthine-containing drinks Emotional stressors Nocturnal Enuresis
What else should you ask in the history? Nocturnal Enuresis
Ask about; The wetting Daytime urination habits Drinking habits Bowel habits Development Behaviour or emotional issues Recent lifestyle changes or stressors Nocturnal Enuresis
Investigations may include a urine dip and blood sugar Management; If <5 years, reassure parents Lifestyle changes Star charts and alarms Desmopressin Nocturnal Enuresis
Encopresis
Passage of stool into underwear after a child is toilet trained Often occurs in the afternoon and evening Children often feels guilty or ashamed, and may try to hide the problem What’s the most common cause of soiling? Encopresis
Constipation is the most common cause; Pain on defecation results in reluctance to pass stool This leads to a build up of stool, which gets stuck and stretches the rectum The muscles are weakened and watery stools can leak around (overflow) Parents may confuse overflow for diarrhoea Encopresis
Other causes of encopresis; Emotional issues Sexual abuse Cause of constipation; Dietary Hypothyroidism Coeliac disease Cystic fibrosis Cow’ milk protein intolerance Hypocalcaemia Hirschprung’s disease Encopresis
History; Frequency of stools Consistency Episodes of incontinence Episodes of soiling Pain or crying on defecation Any associated behaviours When did they first pass meconium Encopresis
On examination; Faecal mass on examination Peri-anal fissures Rectal examination rarely performed First line investigations may include TFTs, coeliac screening and AXR for faecal impaction Encopresis
Conservative measures; Increased fluids and fibre Encourage appropriate toilet habits and star charts Avoid punishment for soiling/accidents Laxatives; Lactulose/movicol Suppositories and enemas; Used only under specialist advice Encopresis
Disimpaction; Daily increasing osmotic laxative for 2 weeks If not effective addition of stimulant Addition of suppositories/enemas under specialist Manual evacuation Once successful laxatives can be weaned, but not stopped Long-term treatment allows rectum to return to normal size and sphincter function to be regained Encopresis

Nocturnal enuresis is common, even in older children and teenagers Ensure no underlying pathology through history taking, urine dip and BM monitoring Reassure parents and provide lifestyle advice Star charts and enuresis alarms are first line Key Learning Points
Children usual gain bowel control before gaining bladder control The most common cause of encopresis is constipation, affecting up to 30% of children Take and good history and perform baseline investigations to rule out other causes Initial management involves dietary and lifestyle advice, before starting osmotic laxatives Key Learning Points
