Urge incontinence is a sudden, overwhelming need to pass urine that is almost impossible to hold, with leakage happening before you reach the toilet. It becomes more common with age and with obesity. Unlike stress incontinence, which is overwhelmingly a female condition, urge incontinence affects men and women in similar numbers — and in older men it is the commonest form of incontinence there is.

The first thing worth saying to anyone living with this: it is not carelessness and it is not a matter of willpower. The bladder is contracting on its own, without permission and without warning. No amount of trying harder overrides a muscle that has already started to squeeze — which is why treatment works and self-blame does not.

Who actually gets it, and why the usual summary is misleading

Urinary incontinence as a whole is a predominantly female problem: population studies put it at roughly 49% of women against 22.6% of men, so about two to three times more common in women. That headline figure is true, and it is also the reason a great many men never mention their symptoms to anyone.

Break it down by type and the picture changes completely:

• Stress incontinence is overwhelmingly female — around 26% of women against 3% of men. This is the type that drives the whole female predominance.
• Urge incontinence is close to equal between the sexes. In one large population study it was 5.3% of women and 5.0% of men. Among men over 60 it is the predominant form.
• 混合性尿失禁 — both mechanisms together — is more common in women.
• In men, two further patterns sit outside the usual questionnaires: post-void dribbling, 、および stress incontinence after prostate surgery, which is a distinct problem with its own treatments.

So the accurate statement is not that incontinence is a women’s condition, nor that this particular type is a men’s condition. It is that the female predominance in incontinence overall comes almost entirely from the stress type — and urge incontinence, the subject of this article, arrives at a man’s door about as often as a woman’s. Prevalence rises with age in both.

Note, August 2026: an earlier version of this article stated that urinary incontinence is predominantly a male problem. That was wrong, and the figures above replace it.

の3つの主な原因 失禁を促す

1. Detrusor overactivity — the bladder muscle contracts involuntarily and without warning, instead of waiting until you decide to go. This produces the sudden powerful urge and the leak that follows it, and it is the commonest mechanism.
2. 膀胱のコンプライアンス低下 — a healthy bladder stretches like a resilient balloon as it fills. When it loses that give, pressure rises early, and urine is pushed out through the urethra before the bladder is anywhere near full.
3. Bladder hypersensitivity (sensory urgency) — the nerve endings in the bladder lining over-report. Caffeine, cold and ordinary filling all generate an exaggerated urge signal, and the bladder feels desperate at a volume it should handle comfortably.

When urgency is not simply urgency

Most urgency is exactly what it appears to be. A few things travelling with it change the priority, and are worth acting on rather than adding to a diary:

• 血尿, with or without pain — this needs investigation on its own terms and should not be attributed to an overactive bladder.
• Fever, shivering, or pain in the flank or lower back alongside urinary symptoms — same-day assessment, not a clinic appointment. In Thailand the emergency number is 1669.
• New numbness around the genitals or inner thighs, weakness in the legs, or loss of bowel control with new urinary symptoms — an emergency department the same day.
• Sudden inability to pass urine at all, with a painful lower abdomen — acute retention, which needs treatment that day.

How it is assessed

Assessment covers a full history, physical examination, a voiding diary and any imaging needed to exclude other causes. The diary does more work than patients expect — it turns a vague impression into a record of when the urgency strikes, how much you passed and what you had been drinking, which is often where the pattern becomes obvious.

Where symptoms are mixed, or have not responded as expected, a 尿流動態検査 measures what the bladder is actually doing as it fills — confirming involuntary contractions, and separating urge incontinence from 腹圧性尿失禁 and from a bladder that is failing to empty. Dr. Soarawee performs urodynamic studies at Bangkok Hospital Headquarters.

In men, one extra step matters before treatment starts. An enlarged prostate can produce urgency by obstructing the outlet, and a bladder that is not emptying properly can cause exactly the same symptoms as an overactive one — with the important difference that the standard overactive-bladder medications can make it worse. Measuring how well the bladder empties is therefore part of the assessment, not an optional extra.

Treatment: the AUA’s three levels

1. Behavioural therapy — first line

• Bladder training — gradually stretching the interval between visits to the toilet, so the bladder relearns to hold more.
• Cutting bladder irritants — caffeine above all, plus alcohol, carbonated drinks and smoking. Caffeine is worth trying first because the effect is often noticeable within days rather than weeks.
• Weight loss where relevant, since obesity is one of the two established risk factors.
• Pelvic floor training (Kegel exercises) — a strong pelvic floor helps suppress an urge long enough to reach the toilet. These work for men too, and are the mainstay after prostate surgery.

2. Medication — second line

• 抗ムスカリン剤 — block the involuntary bladder contractions. Dry mouth and constipation are the usual side effects, and constipation is worth watching since it aggravates bladder symptoms in its own right. They are used with more caution in older patients, and are avoided where the bladder is already emptying poorly.
• ベータ3アゴニスト — relax the bladder muscle to improve storage, generally with fewer anticholinergic side effects. Blood pressure is monitored during treatment.

A partial response to the first drug is not the end of the line — the dose can be adjusted or a different agent tried, and many patients settle on the second or third attempt.

3. Bladder botulinum toxin (Botox) — third line

Where behaviour and medication have not been enough, botulinum toxin is injected into the bladder wall through a cystoscope, temporarily quietening the overactive muscle. It works well in the right patients, and the effect lasts roughly 6 months, so maintenance injections are needed to sustain it. The trade-off to understand before agreeing to it is that the bladder can be quietened too far, leaving some patients temporarily unable to empty and needing to pass a catheter themselves until the effect wears off.

Bladder botulinum toxin injection is not performed at Bangkok Hospital Headquarters — if your case reaches that point, a referral to a centre that offers it can be arranged. Everything before it, including the urodynamic study and both earlier treatment levels, is available here, and the great majority of patients are managed successfully without ever needing the third line.

Outcomes vary a great deal between patients, so the goal is worth agreeing at the start. Some are aiming for complete dryness; for others, being able to sit through a meal or a meeting without anxiety is the win that matters. Both are legitimate targets, and naming yours makes the treatment plan a good deal easier to judge.

切迫性尿失禁に関するよくある質問

切迫性尿失禁と腹圧性尿失禁の違いは何ですか？

Urge incontinence is urine leakage triggered by a sudden, uncontrollable urge to void — the bladder contracts involuntarily before the patient can reach the toilet. Stress incontinence, by contrast, is leakage caused by physical exertion that increases abdominal pressure (coughing, sneezing, lifting, laughing), without an urge sensation. The two differ sharply in who gets them: stress incontinence is overwhelmingly female, at roughly 26% of women against 3% of men, while urge incontinence is close to equal between the sexes. Both can coexist as mixed incontinence, and a urodynamic study can establish which mechanism is dominant.

Is urinary incontinence more common in men or women?

Incontinence overall is about two to three times more common in women, with population studies reporting roughly 49% of women against 22.6% of men. That gap comes almost entirely from stress incontinence, which is overwhelmingly female. Urge incontinence, the type described in this article, is close to equal between the sexes — around 5.3% of women and 5.0% of men in one large population study — and among men over 60 it is the commonest form of incontinence. Prevalence rises with age in both sexes. Men also experience two patterns that general surveys tend to miss: post-void dribbling, and stress incontinence following prostate surgery.

尿意切迫症を改善できる生活習慣の変更にはどのようなものがありますか？

Per AUA guidelines, first-line management is behavioural therapy. This includes bladder training (gradually increasing the time between bathroom visits), reducing or eliminating bladder irritants such as caffeine and alcohol, maintaining a healthy body weight, and pelvic floor muscle training (Kegel exercises, which work for men as well as women). These interventions can significantly reduce urge episodes and leakage frequency without medication. Keeping a voiding diary to track fluid intake, voiding times and leakage episodes helps both patient and urologist identify patterns and monitor progress.

過活動膀胱による尿意切迫感の治療としてボトックス注射が推奨されるのは、他の治療法（生活指導、内服薬など）で十分な効果が得られない場合です。

Intravesical botulinum toxin (Botox) injection is recommended as a third-line treatment when behavioural therapy and oral medications have not provided adequate symptom control. The procedure is performed via cystoscopy, and Botox temporarily quietens the overactive bladder muscle, reducing involuntary contractions and urgency episodes. Effects typically last about 6 months, after which repeat injection is required to maintain benefit. The main trade-off is that the bladder can be quietened too far, so some patients temporarily cannot empty and need to pass a catheter themselves until the effect wears off. This procedure is not performed at Bangkok Hospital Headquarters; assessment, urodynamic study and the first two treatment levels are provided there, with referral arranged if third-line treatment is needed.

When should urinary urgency be seen urgently rather than in clinic?

Go to an emergency department the same day, or call 1669 in Thailand, for fever or shivering with pain in the flank or lower back alongside urinary symptoms; new numbness around the genitals or inner thighs, leg weakness or loss of bowel control together with new urinary symptoms; or sudden inability to pass urine at all with a painful lower abdomen. Blood in the urine, with or without pain, needs investigation in its own right and should not be assumed to be an overactive bladder.
