What should I do if I have incontinence of urine?
If you have any involuntary loss of urine which is a social or hygienic problem, you should contact your GP for further advice
Incontinence can be divided broadly into the following types but 90% of patients suffer from stress and/or urge incontinence:
- Stress incontinence - leakage during periods of abdominal pressure (coughing, sneezing, lifting, straining);
- Urge incontinence - leakage which follows an irresistible urge to pass urine;
- Mixed incontinence - combined stress & urge incontinence;
- Overflow incontinence - inability to empty the bladder with resulting overflow of urine;
- Functional incontinence - inabilty to use the toilet in time due to poor mobility or brain disorders;
- Continuous incontinence - constant leakage of urine due to an inherited abnormality or sphincter (valve) injury (often caused by surgery);
- Post-micturition dribble - leakage from the urethra a few minutes after passing urine (not to be confused with terminal dribbling when it is difficult to shut off the stream immediately after passing urine - usually a sign of prostatic obstruction); and
- Giggle incontinence - tends only to occur in young girls and normally resolves as the child grows.
What are the facts about incontinence of urine?
- there may be as many as 3 million people in the UK with urinary incontinence;
- 60-80% of these patients have never sought medical advice for their condition and 35% view it simply as part of the ageing process;
- incontinence is caused by bladder abnormalities and/or sphincter (valve) weakness;
- stress incontinence is due to sphincter weakness for which the commonest causes are multiple childbirth or prolonged labour;
- urge incontinence is caused by bladder abnormalities for which the commonest cause is an overactive bladder (OAB);
- conservative treatment can be successful in improving most forms of incontinence; and
- surgery is effective in incontinence if conservative measures do not work, but there is a late failure rate for all types of surgery.
What should I expect when I visit my GP?
Your GP should work through a recommended scheme of assessment for incontinence of urine. This will normally include one or all of the following:
1. A full history
Your GP will take a structured, urological history to ascertain what type of incontinence you have and how this affects your day-to-day activities. You may be asked to complete a questionnaire in advance of your appointment to help your GP obtain a more accurate picture.

Your past medical and obstetric history are important in any discussion, as are your daily fluid intake, the drugs you are taking, your bowel function, your smoking habits and any other urinary symptoms you may be experiencing.
2. A physical examination
A full physical examination will be performed, including measuring your blood pressure and assessment of your body mass index (BMI). Particular attention will be paid to the abdomen (to feel for an enlarged bladder) and to vaginal or rectal examination. It is helpful to have a full bladder when you are examined because it may mean that you can reproduce the leakage for your GP.
A full neurological examination with assessment of your reflexes should also be performed.
3. Additional tests
The usual tests performed are:
a. General blood tests
The actual tests performed will be left to your GP's discretion. It is usual to measure kidney function and to check the blood cells for anaemia or other problems.
b. Urine tests
A routine dipstick test will be performed. A urine sample will normally be sent to the laboratory to exclude infection.
c. Other specific tests
Your GP may wish to arrange an ultrasound scan (pictured). This is to check your kidneys, to assess your bladder emptying and to find out whether your symptoms are caused by a problem within or close to the bladder. Thereafter, additional tests will only be performed after your GP refers you to a uro-gynaecology clinic. These may include:
What could have caused my incontinence?
The causes of incontinence are many and depend on the type of incontinence. In some patients, there is more than one cause and different types of incontinence may also co-exist (e.g. combined urge & stress incontinence)
This is usually the result of sphincter weakness cause by childbirth, loss of hormone support due to the menopause, hysterectomy or increasing age. It is also made worse by obesity
This is due to bladder muscle overactivity. In most patients, the underlying cause is unknown. Urinary infections, bladder stones, bladder cancer, neurological disease (e.g. stroke, Parkinson's disease) and obstruction (usually prostatic enlargement) can all cause urge incontinence
This is usually due to chronic retention of urine (in men) but may also be caused by a congenital abnormality of the bladder or by spinal cord injury
This is usually due to an inherited problem, injury to the pelvis, a fistula from the bladder to a point below the sphincter or a complication of surgery
A cause is rarely found for this type of incontinee. In a small proportion of patients, it may be due to to a urethral diverticulum (pictured) or a stricture of the urethra. These abnormalities can be demonstrated by a special ultrasound scan of the urethra which your urologist may arrange.
What treatment is available for this problem?
If you have an enlarged bladder, a mass arising from the pelvis (or urinary tract), blood in your urine or a large, troublesome vaginal prolapse, your GP will arrange your referral to a urologist or uro-gynaecologist.
In most patients, however, your initial management will take place under the supervision of your GP.
2. Stress incontinence
Download a summary of treatment options for stress incontinence.
- Weight loss - may reduce the incontinence to manageable levels without any further treatment;
- Physiotherapy - combined with electrical stimulation or the use of vaginal cones can improve many patients with stress incontinence;
- Oestrogen supplements - may help women with incontinence due to post-menopausal tissue atrophy; and
- Drugs - there are now some drugs available which can help women with stress incontinence.
3. Urge incontinence
Download a summary of treatment options for overactive bladder.
- drugs - designed to inhibit uncontrolled bladder contractions;
- behavioural modification/biofeedback;
- hypnosis; and
- Treat the underlying cause - e.g. prostate obstruction, bladder tumour, bladder stone or urethral stricture;
- Stretching of the bladder - by overfilling with fluid at the time of telescopic inspection under general anaesthetic;
- Botox injections - by injecting into the bladder wall using a telescope under local or general anaesthetic;
- Sacral neuromodulation - implantation of a stimulator & electrodes into the nerves which supply the bladder;
- Augmentation cystoplasty - enlargement of the bladder using a segment of bowel; or
- Diversion of urine into a conduit should be regarded as a last resort when all other measures have failed.
5. Continuous incontinence
If there is a fistula between the bladder and vagina or rectum causing continuous incontinence, this can be repaired surgically. An urethral catheter or intermittent self-catheterisation may be preferred if surgery is not appropriate (see above for details).

6. Post-micturition dribble
The vast majority of men with post-micturition dribble have no underlying problem apart from a failure of the normal "milk-back" mechanism after passing urine. Simple massaging of the urethra towards the tip of the penis can reduce troublesome dribbling. Thijs helps to expel the last remaining drops of urine.
If an underlying cause is identified on ultrasound scanning (e.g. urethral stricture or diverticulum), telescopic surgery may be advised, although this does not always eliminate the dribbling completely.
