Urinary incontinence in older adults
Urinary incontinence is not a normal part of ageing: first look for and correct reversible causes, then identify the type (stress, urge, mixed, overflow, functional) and start with behavioural treatment, and only then drugs — and in an older adult prefer a drug that is not anticholinergic.
Why it matters in the exam
The exam presents a woman who leaks urine on coughing (stress), a man who cannot reach the toilet in time (urge), or a patient with diabetes or an enlarged prostate who dribbles constantly with large residuals (overflow). Candidates are asked for the first test (urinalysis, bladder diary, post-void residual) and the first treatment for each type.
Common points: pelvic floor muscle training is first line in stress incontinence; bladder training and timed voiding in urge incontinence; mirabegron is preferred to oxybutynin in older adults because of the cognitive risk; an indwelling catheter is not a treatment for incontinence, only for retention that cannot be resolved, a healing pressure injury or comfort at the end of life.
Urinary incontinence is very common in old age, especially in women and in residents of institutions, and it affects mood, loneliness and the risk of night-time falls and skin damage. Many patients do not mention it on their own, so ask about it directly. The exam also asks about passing urine at night (nocturia) — look for heart failure, leg oedema, diabetes, sleep apnoea and late drinking — and about treating an older man with urge symptoms and an enlarged prostate, in whom the residual is checked before a bladder drug is added.
Key points
- Incontinence is not normal in older age; reversible causes first.
- Urinalysis, bladder diary and residual; above 200 mL — suspected retention.
- Stress → pelvic floor training; urge → bladder training and a beta-3 agonist.
- Overflow → treat the obstruction and intermittent catheterisation.
- Indwelling catheter — only for unresolvable retention, a healing pressure injury or comfort at the end of life.
Summary table
| Type | Mechanism and picture | First treatment |
|---|---|---|
| Stress | Weak pelvic floor or sphincter; leakage with coughing or effort | Pelvic floor training for at least 3 months; then pessary or mid-urethral sling |
| Urge | Detrusor overactivity; sudden urge | Bladder training, less caffeine; mirabegron or vibegron |
| Mixed | Stress and urge together | Treat the dominant component first |
| Overflow | Obstruction (prostate) or weak detrusor (diabetes); large residual | Treat the obstruction; intermittent catheterisation |
| Functional | Problem with mobility or cognition, normal bladder | Help to reach the toilet, prompted voiding |
