Urinary incontinence is the involuntary leakage of urine. It means a person urinates when they do not want to. Control over the urinary sphincter is either lost or weakened.
Urinary incontinence is a common problem that affects many people.
According to the American Urological Association, one-quarter to one-third of men and women in the United States experience urinary incontinence.
Urinary incontinence is more common among women than men. An estimated 30 percent of females aged 30-60 are thought to suffer from it, compared to 1.5-5 percent of men.
Fast facts on urinary incontinenceHere are some key points about urinary incontinence. More detail is in the main article.
- Urinary incontinence is more common in females than in males.
- There are a number of reasons why urinary incontinence can occur.
- Obesity and smoking are both risk factors for urinary incontinence.
What is urinary incontinence?
Urinary incontinence is a common problem.
Urinary incontinence is when a person cannot prevent urine from leaking out.
It can be due to stress factors, such as coughing, it can happen during and after pregnancy, and it is more common with conditions such as obesity.
The chances of it happening increase with age.
Bladder control and pelvic floor, or Kegel, exercises can help prevent or reduce it.
Treatment will depend on several factors, such as the type of incontinence, the patient’s age, general health, and their mental state.
Pelvic floor exercises, also known as Kegel exercises, help strengthen the urinary sphincter and pelvic floor muscles – the muscles that help control urination.
- Delaying the event: The aim is to control urge. The patient learns how to delay urination whenever there is an urge to do so.
- Double voiding: This involves urinating, then waiting for a couple of minutes, then urinating again.
- Toilet timetable: The person schedules bathroom at set times during the day, for example, every 2 hours.
Bladder training helps the patient gradually regain control over their bladder.
Medications for urinary incontinence
If medications are used, this is usually in combination with other techniques or exercises.
The following medications are prescribed to treat urinary incontinence:
- Anticholinergics calm overactive bladders and may help patients with urge incontinence.
- Topical estrogen may reinforce tissue in the urethra and vaginal areas and lessen some of the symptoms.
- Imipramine (Tofranil) is a tricyclic antidepressant.
The following medical devices are designed for females.
- Urethral inserts: A woman inserts the device before activity and takes it out when she wants to urinate.
- Pessary: A rigid ring inserted into the vagina and worn all day. It helps hold the bladder up and prevent leakage.
- Radiofrequency therapy: Tissue in the lower urinary tract is heated. When it heals, it is usually firmer, often resulting in better urinary control.
- Botox (botulinum toxin type A): Injected into the bladder muscle, this can help those with an overactive bladder.
- Bulking agents: Injected into tissue around the urethra, these help keep the urethra closed.
- Sacral nerve stimulator: This is implanted under the skin of the buttock. A wire connects it to a nerve that runs from the spinal cord to the bladder. The wire emits an electrical pulse that stimulates the nerve, helping bladder control.
Surgery is an option if other therapies do not work. Women who plan to have children should discuss surgical options with a doctor before making the decision.
- Sling procedures: A mesh is inserted under the neck of the bladder to help support the urethra and stop urine from leaking out.
- Colposuspension: Lifting the bladder neck can help relieve stress incontinence.
- Artificial sphincter: An artificial sphincter, or valve, may be inserted to control the flow of urine from the bladder into the urethra.
Urinary Catheter: A tube that goes from the bladder, through the urethra, out of the body into a bag which collects urine.
Absorbent pads: A wide range of absorbent pads is available to purchase at pharmacies and supermarkets, as well as online.
The causes and the type of incontinence are closely linked.
- pregnancy and childbirth
- menopause, as falling estrogen can make the muscles weaker
- hysterectomy and some other surgical procedures
The following causes of urge incontinence have been identified:
- cystitis, an inflammation of the lining of the bladder
- neurological conditions, such as multiple sclerosis (MS), stroke, and Parkinson’s disease
- enlarged prostate, which can cause the bladder to drop, and the urethra to become irritated
This happens when there is an obstruction or blockage to the bladder. The following may cause an obstruction:
- an enlarged prostate gland
- a tumor pressing against the bladder
- urinary stones
- urinary incontinence surgery which went too far
This can result from:
- an anatomical defect present from birth
- a spinal cord injury that impairs the nerve signals between the brain and the bladder
- a fistula, when a tube or channel develops between the bladder and a nearby area, usually the vagina
- some medications, especially some diuretics, antihypertensive drugs, sleeping tablets, sedatives, and muscle relaxants
- urinary tract infections (UTIs)
