Urinary Incontinence in Women — Label, Train & Step Up
Estimates of urinary incontinence range from 3% to 55% of women, depending on the definition; at least half never tell a doctor
Stress, urge, mixed, overflow and functional are the types; mixed is the commonest overall, and you treat the more bothersome symptom
Classify the leak before choosing treatment
First-line treatment for all types is conservative and has no major harms: weight loss, fluid and caffeine changes, bladder training and pelvic floor muscle training
Up to 38% of women with stress incontinence alone are cured after at least 3 months of pelvic floor training
Drugs for urge give modest benefit and cure is rare; combining a drug with behavioural therapy works better than either alone
Systemic oestrogen can make incontinence worse
| Type | She leaks when | Typical woman |
|---|---|---|
| Stress | She coughs, sneezes, laughs or exerts herself | Younger women; second most common in older women |
| Urge | There is a sudden strong desire to pass urine; often frequency and nocturia | Most common in older women; caused by detrusor overactivity |
| Mixed | Both stress and urge | The most common overall |
| Overflow | The bladder is full and dribbles | Drugs with anticholinergic effect, or nerve disease |
| Functional | She cannot reach the toilet in time | Limited mobility, memory or mood |
Ask about triggers, urgency, frequency, nocturia, pad use, a bulge, bowel symptoms, pain, blood in the urine, deliveries and operations, drugs, and how much it bothers her
Look for reversible causes: urinary infection, constipation, vaginal atrophy, drugs such as diuretics and sedatives, poor mobility, and confusion (from memory)
Ask her to keep a bladder diary and fill in a symptom questionnaire
Examine the abdomen, nervous system and pelvis; try to show stress leakage with a cough; check for prolapse and for atrophy
Send a urinalysis and measure the post-void residual when indicated
Before surgery, objectively demonstrate stress leakage and check bladder emptying; do urodynamics when the diagnosis is unclear (from memory)
| Option | What to do | Notes |
|---|---|---|
| Lifestyle | Lose weight if overweight (stress); cut fluids, caffeine and fizzy drinks; treat constipation; stop smoking | Useful for all types |
| Pelvic floor muscle training | 3 sets of 8 to 10 contractions, each held 6 to 8 seconds, 3 to 4 times a week, for 15 to 20 weeks; extend the hold to 10 seconds | Most effective for stress incontinence; supervised teaching helps |
| Bladder training | Suppress the urge, then extend the interval by 30 to 60 minutes; aim to pass urine every 3 to 4 hours | For urge; scheduled or prompted voiding if memory is poor |
| Vaginal pessary or devices | A pessary for stress incontinence if she is pregnant, unfit for surgery or after failed surgery; tibial nerve stimulation for urge | Urethral plugs carry a high risk of infection |
| Drugs for urge | An antimuscarinic for 4 to 8 weeks (long-acting and selective if possible), or mirabegron | Avoid antimuscarinics in dementia, narrow-angle glaucoma and retention, and with caution in older women; mirabegron raises blood pressure |
| Vaginal oestrogen | Low-dose, for atrophy and sometimes urge | Systemic oestrogen may worsen incontinence |
| Duloxetine for stress | Off-label | Reduces leakage but does not cure; 45% stop because of side effects |
| Botulinum toxin, sacral neuromodulation | For urge that does not respond to drugs | Botulinum lasts 3 to 6 months; neuromodulation is an implant |
| Stress surgery | Midurethral sling (TVT is the most common), Burch colposuspension, bulking agents | Only after conservative care fails; risks include new urgency, voiding difficulty, prolapse and repeat surgery; bulking cures or improves 18 to 40% |
Leaking urine is common and treatable; she is not alone and need not feel ashamed
Start with exercises and bladder habits; they work, and have no harm
Drinking less does not cure it: pass urine about every 3 to 4 hours, and avoid caffeine, fizzy drinks and drinking late at night (from memory)
Treat constipation and a chronic cough, because they strain the pelvic floor (from memory)
Medicines can dry the mouth and constipate; the benefit is modest
Surgery is for stress leakage that has not improved; discuss goals, risks and future pregnancy first
Not asking, so she suffers in silence
Starting a drug before classifying the leak
Giving an antimuscarinic to a woman with retention, dementia or glaucoma
Expecting drugs to treat stress incontinence
Operating without demonstrating stress leakage or measuring emptying
Missing a fistula in a woman who leaks constantly after delivery or surgery (from memory)
Prescribing systemic oestrogen for leakage
Teaching pelvic floor exercises once and not following up
