Urinary incontinence is the loss of voluntary bladder control leading to urine leakage. It can be temporary or long-lasting. Incontinence is a symptom, not a condition in and of itself.
The causes may vary with the type of incontinence. There may be several different causes. The cause may also be unclear.
Leakage may happen when you laugh, sneeze, lift heavy objects, or exercise. Activities like these can increase pressure on the bladder. The leakage may be caused by:
- Weakening of the muscles that suspend the bladder
- Weakening of the muscles that control urine flow
- Damage to the muscles that control urine flow following prostate surgery
This is also known as overactive bladder. It is a loss of bladder control following a strong urge to urinate. You may not be able to hold urine long enough to make it to a toilet. It may be caused by:
This occurs when the bladder will not empty. As a result, the urine builds up. This will cause an overflow and leaking of urine. It may be caused by:
- Prostate enlargement
- Bladder that is blocked, such as by a scar in the urethra (stricture)
- Fecal impaction putting pressure on the urethra
- Drugs (eg, antidepressants, hypnotics, antipsychotics, beta-blockers, antihistamines, calcium channel blockers)
- ]]>Vitamin B12]]> deficiency
- Weak bladder muscles
- Nerve damage
There is normal bladder control, but you are unable to reach the toilet in time. It may be a result of a condition like severe arthritis. Drugs which cause confusion or sedation can also cause functional incontinence.
These risk factors increase your chance of developing urinary incontinence:
- Age: older than 65
- History of prostate surgery
- Prostate enlargement due to benign prostatic hyperplasia]]> (BPH), infection, or ]]>prostate cancer]]>
- ]]>Urinary tract infection]]>
- Chronic lung disease
- ]]>Dementia]]> (including ]]>Alzheimer’s disease]]> )
- Multiple sclerosis
- Spinal cord injury or disease
Use of certain substances or medications:
- Cholinergic agents
Urinary incontinence is a symptom of other conditions. Any loss of bladder control can be considered incontinence.
Your doctor will ask about your symptoms and medical history. You will be asked about your urine leakage and how often you empty your bladder. A physical exam will be done to look for any physical causes, such as blockages or nerve problems. You will keep a diary of your bladder habits. You may be referred to a specialist. A urologist is a doctor who focuses on urinary issues.
Tests may include:
- Stress test—You relax, then cough as your doctor watches for loss of urine. This will confirm if you have stress incontinence.
- Urine tests
- Tests to determine problems with your prostate (eg, prostate exam, blood tests)
- Blood tests to detect diabetes
- Ultrasound—This test uses sound waves to examine structures inside the body to determine if any urine remains in your bladder after urinating.
- Cystoscopy]]> —A thin tube with a tiny camera is inserted into the urethra to view the urethra and bladder.
- Urodynamic tests—These tests are used to measure the flow of urine and the pressure in the bladder.
Treatments may include:
Behavioral therapy includes:
Making muscles stronger by doing
- This strengthens the muscles that hold the bladder in place and control urine flow.
- Painless electrical stimulation is sometimes used. It can strengthen the muscles more quickly. It is helpful for stress incontinence.
- Bladder training: A regular schedule is set to empty your bladder. You will also be asked to drink fewer liquids.
Losing weight may help to reduce the number of episodes due to stress or urge incontinence. Talk to your doctor about a weight loss program that is right for you.
Medicines may be prescribed to relax the bladder muscles. These types of medicines, called anticholinergics, are often used in treating urge incontinence. Examples include:
In men, surgery may be done to relieve a physical blockage due to an enlarged prostate. Other procedures involve surgical repair or implants into the bladder sphincter. The sphincter is the gate that allows the urine to flow through.
To stimulate the nerves, there are devices like Urgent PC and Inter-Stim. The procedure may involve implanting a thin lead wire with a small electrode tip. In some cases, the tibial nerve, which extends down to the ankle, is stimulated. This electronic stimulation therapy can be done as a series of treatments in the doctor's office.
Absorbent diapers are often used by men with incontinence. Catheters are sometimes used to treat more severe cases. External (condom) or internal (Foley) catheters may also be used. Another option is a penile clamp. These clamps are padded and have a sleeve to absorb leakage.
