Overview

Urinary incontinence is a condition in which there is an uncontrollable leakage of urine causing a social or hygienic problem.

Loss of urine control, or urinary incontinence occurs in people of all ages, but is common in older people. At least 1 in 10 people of the age of 65 or older suffer from incontinence. This condition can range from the discomfort of slight losses of urine to the disability and shame of severe, frequent wetting.

Urinary incontinence affects all ages, both sexes and people of every social and economic level. The exact number of people with incontinence is not known, but the total number of people affected may be far greater than current estimates.

Many people with incontinence withdraw from social life and try to hide the problem from their families, friends, and even their doctor. These reactions are unfortunate because in most cases, incontinence can be treated and controlled, if not cured.

People who have problems controlling urination should see their doctor. Even when incontinence cannot be completely cured, modern products and ways of managing the condition can ease the discomfort and inconvenience it causes.

Conditions Treated

Urinary incontinence in men & women is of the following types:                                                                                                      top

  • Stress incontinence: Stress incontinence is the leakage of urine during exercise, coughing, sneezing, laughing, walking, lifting heavy objects such as lifting a bag of groceries, rising from a sitting to a standing position, or other body movements that put pressure on the bladder. The word 'stress' in this case does not mean emotional stress. The stress referred to here is physical in nature. It refers to an increased pressure on the bladder when ordinary physical activities are performed. The time period during which leakage occurs may be very short. This type of incontinence may be due to poor bladder support or a weak/damaged sphincter. It is the most common type of incontinence and can almost always be cured.

    Most women with stress urinary incontinence have weak pelvic muscles. These are the muscles that support the bladder, bladder neck and the urethra (the urinary passage). Pregnancy, childbirth and prior pelvic surgery are among the reasons for weakened pelvic muscles.

    Another possible cause for stress incontinence in women is a weakened urethral sphincter muscle itself. Both of these, weak pelvic muscles and a weakened urethral sphincter muscle, may co-exist in the same patient.

  • Urge Incontinence: Urge incontinence is the inability to hold urine long enough to reach a toilet. In this type of incontinence, an
    overactive bladder contracts without you wanting it to do so. You may feel as if you can't wait to reach a toilet. There is the sudden strong urge to urinate, with an uncontrollable rush of urine. It is often found in people who have conditions such as diabetes, stroke, dementia, Parkinson's disease and multiple sclerosis. It can also be a warning sign of early bladder cancer. In men, it is often a sign of an enlarged prostate. It can, however, occur in otherwise healthy, older people.

  • Overflow Incontinence: Overflow incontinence is the leakage of small amounts of urine from a bladder that is always full. It results when the bladder is allowed to become so full that it overflows. In this form of incontinence, the bladder never completely empties, and the urine stream is weak, with a frequent or constant dribble. Overflow incontinence can occur when the flow of urine from the bladder is blocked as in the case of a blocked urethra, when there is loss of normal bladder function in some people with diabetes, or due to bladder muscle weakness.

  • Functional Incontinence: Functional incontinence occurs in many older people who have normal urine control but who have     top
    difficulty reaching a toilet in time because of arthritis or other crippling disorders.

  • Total Incontinence: Total incontinence occurs when there is a complete loss of bladder control, usually occurring after some form of surgery to the lower urinary tract.

  • Mixed Incontinence: is a combination of urge and stress incontinence.

Diagnosis & Tests

  • For Both Men & Women

    Incontinence may be brought on by an illness accompanied by fatigue, confusion or hospital admission. Incontinence is sometimes the first and only symptom of a urinary tract infection. Curing the illness will usually relieve or clear up the incontinence.

Some possible causes of incontinence are:

    • Diseases and disorders involving the nerves and/or the muscle

    • A blocked urethra due to an enlarged prostate

    • Weakness of the pelvic floor muscles

    • Effects of medication

    • Constipation                                                                                                                                                        top

The first and most important step in treating incontinence is to see a doctor for a complete medical examination that focuses on the urinary system, the nervous system and the reproductive organs. Some of the following tests may be performed:

    • Urinalysis: A sample of your urine will be tested for the presence of infection, blood or other abnormalities.

    • Uroflowmetry (Urine Flow Test): Uroflowmetry (urine flow test) is the simplest of the urodynamic tests. [Urodynamics are special outpatient tests used to assess the normal and abnormal function of the urinary tract, especially the bladder and the urethra (the ‘water-pipe’ leading from the bladder to the outside of the body). These range from the simple to the more sophisticated depending upon the complexity of your problem].

      This test measures the rate of urine flow as well as the amount of urine passed. You will have to come to the clinic with a reasonably full bladder (as per what feels comfortable to you), sit on a modified toilet seat (called a micturition chair) and, in private, pass urine in the usual way, into a flow meter.


    • Residual Urine Measurement: This test is performed to find out whether any urine remains after you have attempted to empty your bladder. Immediately after your uroflowmetry, we will measure the amount of urine left in your bladder (residual urine) in order to detect how well you have emptied your bladder. Residual urine is measured by placing a bladder scanner over your bladder – a painless procedure lasting only for a few seconds.

      If your uroflowmetry and/or residual urine are abnormal, you will then require a voiding cystometry to determine the cause of your  difficulty in passing urine.

    • Filling and Voiding Cystometry (CMG): Filling cystometry will tell us about the sensation of your bladder, how much it can hold, how 'elastic' it is, the pressure changes when it is being filled up, when you are changing posture, standing up and coughing, and whether you have any urge or stress incontinence of urine. In this way, it can help us make a diagnosis of whether your bladder is stable (normal) or unstable (detrusor instability), whether you have genuine stress incontinence of urine (stable bladder with stress incontinence of urine demonstrated) or both the latter two conditions.

      Voiding cystometry is performed immediately after the filling cystometry; it is used to differentiate as to whether you have an obstruction of the urethra ('water pipe'), or an under-active bladder as a cause of your difficulty in passing urine.

      When you arrive for these two tests, you will have to empty your bladder completely, in the usual way, in the toilet. We will then make you lie down on an examination couch, clean you down below using sterile cotton swabs and an antiseptic lotion before inserting a fine tube into your bladder to measure your residual urine. Your bladder will then be gradually filled through this tube with sterile 0.9% salt solution to mimic urine. Another finer tube will also be inserted into your bladder together with the first tube, for the purpose of measuring the pressure changes in your bladder through a computer in the urodynamic machine. We will also have to insert a fine catheter into your back passage for measuring pressure changes in your 'tummy' (abdomen) at the same time. This is to ensure that the computer will automatically calculate the true pressure changes within your bladder (detrusor pressure). Otherwise, any pressure changes in your abdomen, such as changing posture, standing and coughing, will show a false rise in pressure in your bladder.

      During the filling cystometry we will make you sit up on a modified toilet seat and fill your bladder until you finally feel like passing urine. We will then remove the filling tube, make you to stand up and cough 10 times on a pre-weighed incontinence sheet to determine the absence or presence, and severity of stress incontinence of urine.

      After this you will have to sit down on the modified toilet seat again, to empty your bladder completely into the flow meter, in order to complete the voiding cystometry.

    • Urethral Pressure Profile (UPP): UPP will only be performed in some of those patients who have had previous failed surgery for incontinence. As this test is not commonly undergone, your doctor will explain how it is performed in the case you are required to take it.

    • Video-Cystourethrography (VCU): VCU will only be performed in some of those patients who have had previous failed surgery for incontinence. As this test is not commonly undergone, your doctor will explain how it is performed in the case you are required to take it.

    • Stress Test: While your bladder is full, you may be asked to cough, stand and perform other activities to find out whether these stresses on the bladder cause leakage.

    • Ultrasound: This technique can be used to determine the size and shape of the kidneys, the bladder and the prostate.

    • Cystoscopy: A thin telescope-like instrument called a cystoscope is inserted into the bladder through the urethra. This test allows the physician

  • For Women

    To diagnose the cause, your doctor will take a detailed medical history that includes information on the number of pregnancies, deliveries, other illnesses and injuries, medications being taken and prior surgeries. You may be asked to keep a voiding diary in which you have to record the number of urinations, the volume of uncontrolled leakage and the urine volumes. 

    A physical examination will include both a vaginal and rectal examination, test of nerve function, test for type and amount of leakage, etc.

Treatment                                                                                                                                                                             top

  • For Both Men & Women

    Treatment of urinary incontinence should be tailored to each patient's needs.  The many options include:

    • Certain Behavioural Techniques: Certain behavioural techniques including pelvic muscle exercises, biofeedback and bladder training are helpful in controlling urination. These help a person to sense the filling of the bladder and delay voiding (the passing of urine) until he or she can reach a toilet.

    • Medical Treatment: A number of medications can be used to treat incontinence. However, they must be used carefully under a doctor's supervision.

    • Surgery: Several types of surgery can improve or even cure incontinence that is related to a structural problem such as an abnormally positioned bladder, or blockage due to an enlarged prostate. Devices that replace or aid the muscles controlling urine flow have been tried in people with incontinence. Many of these devices require surgical implantation.

Sometimes, incontinence cannot be cured, but it can be managed in several ways such as through:

    • Specially Designed Absorbent Underclothing: Specially designed absorbent underclothing is available. Many of these garments are no more bulkier than normal underwear and can be worn easily under everyday clothing.

    • Catheterisation: Incontinence may be managed by inserting a flexible tube known as a catheter into the urethra and collecting the urine in a container. However, long-term catheterisation – although sometimes necessary – creates many problems, including urinary tract infections. In men, an alternative to the in-dwelling catheter is an external collecting device. This is fitted over the penis and connected to a drainage bag.

It is important to remember that under a doctor's care, incontinence can be treated and often cured. Even incurable problems can be managed to reduce complications, anxiety and stress.

  • For Women

Treatment of urinary incontinence should be tailored to each patient's needs. The treatments for urinary incontinence in the case of women are as follows: 

    • Pelvic Floor Exercises: The floor of the pelvis is made up of layers of muscle and other tissues – these are called the pelvic floor muscles. These layers stretch like a hammock from the tailbone at the back to the pubic bone in front. A woman's pelvic floor supports the bladder, the womb (uterus) and the bowel. The urethra (front passage), the vagina (birth canal) and the rectum (back passage) pass through the pelvic muscles. The pelvic floor muscle has an important role in bladder and bowel control, and sexual sensation.

      We have control over the pelvic muscles. Like other muscles in the body, exercise strengthens them when they are weak.

The pelvic floor muscles can be weakened by:

      • Pregnancy and childbirth

      • Continual straining to empty your bowels (constipation)

      • Persistent heavy lifting

      • A chronic cough  (such as smoker's cough or chronic bronchitis and asthma)

      • Being overweight

      • Changes in hormone levels at menopause (change of life)

      • Lack of general fitness

It is important for women of all ages to maintain pelvic floor muscle strength. Especially women with stress incontinence, that is, those who regularly lose urine when coughing, sneezing or exercising, should learn these exercises.

For pregnant women, pelvic floor exercises help the body to cope with the increasing weight of the baby. Healthy, fit muscles before childbirth will recover more fully after childbirth.

As women grow older it is important to keep the pelvic floor muscle strong because at menopause the muscles may change and weaken. A pelvic floor exercise routine helps to minimise the effects of menopause on pelvic support and bladder control.

Pelvic floor exercises may be also useful in conjunction with a bladder-training program.

    • Medical Treatment: Medications that are used to treat incontinence must be used carefully under a doctor's supervision. Stress incontinence can be treated non-surgically by means of medications. 

    • Surgery: Presently, there are many simple surgical procedures that have a high degree of success and also provide long-term relief. All the surgical procedures create support for the urethra and the bladder neck in order to prevent urine leakage during physical activity. Stress incontinence that can be treated surgically.

      With respect to the possible complications from surgery for urinary incontinence, serious complications such as death are very rare. The likelihood of blood transfusion is less than 5%. Less serious complications, such as infection, may occur, but are usually easily treated. Retention of urine is a possible complication, but is temporary in most cases. During this period, the urine is drained either with a catheter left in the bladder, or by self-catheterisation. 

      The time spent in the hospital normally ranges from 1 to 5 days, depending upon the type of procedure.   

    • Injection of Bulking Agent: Another type of treatment is injecting a bulking agent into or around the urethra to help the ceiling mechanism. The effectiveness of this, however, decreases over a period of time, requiring re-injection over a six month to a one-year period. The various sling and suspension procedures are performed through very small incisions in the lower abdomen or in the vagina, permitting an early return to activity.
