What is required to maintain continence

Factors involved in maintaining continence
• Recognise the need to go to the toilet
• Identify an appropriate place and time to go to the toilet
• Reach the place identified
• Hold on until that place is reached
• Pass urine/faeces.


What are the risk factors for male urinary incontinence?

Prostate enlargement
Functional impairment
Cognitive impairment


How should male urinary incontinence be investigated?

DRE – prostate
Urine Dip
Post void bladder scan for residual volume
Urinary flow rates if neurological causes suspected


What is involved in a complete continence assessment of either gender?

Review bladder and bowel diary and post micturition bladder scan
Abdominal examination and check for constipation
Urinalysis note mid-stream urine sample is most useful (not urine dip as this can easily be contaminated) and assessment of clinical symptoms of a UTI
Prostate assessment including PR for both sexes
Blood glucose
Drug review – diuretic use?


What general advice can be given for urinary incontinence?

First line general management advice
Switching to decaffeinated drinks, good bowel habit, improving oral intake, regular toileting, pelvic floor exercises and bladder retraining.


What temporary management can be used for urinary incontinence?

Temporarily manage with containment devices


How is stress urinary incontinence managed?

Stress incontinence – pelvic floor exercises, intramural bulking agents


How should urinary incontinence post prostatectomy be managed?

If postprostatectomy then pelvic floor exercises


How is mixed urinary incontinence managed?

Mixed incontinence – pelvic floor exercises, antimuscarinics (avoid oxybutynin due to effect on cognition), treating constipation and retention


How is urinary incontinence influenced by cognitive function best managed?

If cognitive dysfunction induced incontinence, then follow a timed toilet programme


What are the male catheter options in urinary incontinence?

Male catheter options in incontinence
Indwelling (urethral)
Suprapubic – lower rates of UTIs and urine bypassing


What are the indications for an indwelling catheter?

Chronic retention
Skin wounds
Contamination with urine
Distress and disruption caused by incontinence
Unable to perform self-catheterisation


Why are anticholinergics a last resort in urinary incontinence?

Remember that anticholinergics are not good in older people and oxybutynin whilst good for younger patients is not good for older people. Many of the drugs used for bladder stabilisation can also cause postural hypotension leading to increased falls.


What drug classes are used in urinary incontinence?

Beta 3 adrenergic agonists
Alpha 1 receptors antagonists


Name some antimuscarinic drugs used in urinary incontinence, describe what exactly they improve and their common side effects

Tolteradine, Solifenacin, Oxybutynin
and Trospium

Improves frequency and urgency

SE include dry mucosal membranes, constipation, tachycardia, abdominal pain, urinary retention, oedema, weight gain, glaucoma precipitation.

Oxybutinin particularly causes cognition decline


Which beta 3 adrenergic agonist is used in urinary incontinence, when is it used and what are the side effects?


Used if antimuscarinics are contraindicated or clinically ineffective

CI in severe hypertension
Caution if renal/hepatic impairment


Name the 3 alpha 1 receptor antagonists used in urinary incontinence, when are they used and what are each of their respective side effects?

Tamsulosin - Dizziness and sexual dysfunction
CI in postural hypotension

Doxazosin - Heart problems, dry mouth, GI upset, cough, coryza and headache
CI in postural hypotension

Finasteride - Sexual dysfunction

Used in Benign Prostatic Hyperplasia


Is faecal incontinence ever normal?

This is always abnormal and almost always curable and it is abnormal for there to be faeces in the rectum at any time unless passing stool.


What can influence faecal incontinence as we age?

As the body ages the rectum can become more vacuous and the anal sphincter can gape due to a number of factors including haemorrhoids and chronic constipation. Older people cannot exert the same amount of intra-abdominal pressure and muscle tension to force out constipated stool.


What direct causes are there for faecal incontinence

The most common cause of faecal incontinence is faecal impaction with overflow diarrhoea. This accounts for 50% of faecal incontinence.
The second most common cause is neurogenic dysfunction
Other causes – structural anorectal abnormalities such as sphincter trauma, alterations in stool consistency such as infection and IBD, and cognitive/behavioural dysfunction.


What investigations should be done on someone with faecal incontinence?

• A PR is absolutely mandatory in the assessment of faecal incontinence and the rectum, the prostate, anal tone and sensation should all be assessed as well as a visual inspection around the anus.
• Do not assume that a patient who is opening their bowels is not impacted; smearing, small amount of type 1 stool or copious type 6/7 stool with no sensation of defaecation should raise the suspicion of impaction with overflow.
• Impaction can be higher up than the rectum in some cases and a high degree of suspicion should be had if the clinical picture fits, but the rectum is empty.
• Behind every full rectum is often a full bladder and if a patient is found to have urinary retention then they MUST have a PR to assess for an impacted rectum and/or a large prostate if male.


What social and psychological factors should be considered for faecal incontinence?

Diet – optimised depending on stool consistency
Access – to toilet and easily removable clothing
Continence products
Psychological and emotional support


What general management advice should be offered for faecal incontinence?

Pharmacy review and avoid straining
Diet – keep a diary and have a high fibre diet
Bowel habit – try to empty after meal in private comfortable toilets
Continence products – disposable pads, anal plugs, skin care advice and odour control


How should loose stool incontinence be managed?

Regular antidiarrheal, loperamide (augments anal sphincter and reduced motility and secretions, codeine if Loperamide not tolerated)


How is constipation/overflow incontinence managed?

Should be utilising enemas for rectal loading and stool softeners and stimulants. If stool is hard then stimulants will not help as the stool requires softening.

Some enemas will not work if the rectum is loaded with hard stool and will merely fall out.
Manual evacuation is done in difficult cases and the risk of perforation is outweighed by the positive impact on patient symptoms and wellbeing.

Stool softeners such as Docusate are useful


How should faecal incontinence related to cognitive/behavioural dysfunction be managed?

Regular toileting
Good diet


How should faecal incontinence related to sphincter dysfunction be managed?

Pelvic floor exercises
TCA – amitriptyline


How should faecal incontinence related to spinal cord or neurogenic bladder be managed?

Routine even if this mean manual evacuation or digital anorectal stimulation
Sacral nerve stimulation


Name some anti-motility diarrhoea medication, give its mechanism and side effects/CI.

Anti-motility drugs Loperamide (Imodium)

Opiate analogue 40 times more potent than morphine.

Reduce bowel motility increasing time for fluid to reabsorb, also increases anal tone and reduces sensory defecation reflex

Avoid in IBD due to toxic megacolon


What is mebeverine used for?

Reduced colonic hypermobility relieving spasm. Useful when combined with bulk forming agents
