If you find yourself leaking urine during the day or even wetting the bed at night, you may be experiencing symptoms of overflow incontinence.
Overflow incontinence is one of several different types of incontinence, the inability to control urination. Overflow incontinence occurs when you are unable to completely empty your bladder; this leads to overflow, which leaks out unexpectedly. You may or may not sense that your bladder is full. The leakage, which can cause embarrassment and discomfort, is not the only problem. Urine left in the bladder is a breeding ground for bacteria. This can lead to repeated urinary tract infections.
What you eat and drink, as well as the drugs you take, may all have an effect on incontinence symptoms. Use these two charts to learn more about the potential effects of food, drink, and medication on incontinence.
Unlike other types of incontinence, overflow incontinence is more common in men than women. The most common cause in men is an enlarged prostate, which impedes the flow of urine out of the bladder. Other possible causes of overflow incontinence include:
Blockages of the urethra (the tube that carries urine from the bladder to outside the body) from tumors, urinary stones, scar tissue, swelling from infection, or kinks caused by dropping of the bladder within the abdomen
Weak bladder muscles, which are unable to squeeze the bladder empty
If you have problems with incontinence, it's important to speak with your doctor. Determining the type you have and the best treatment for it will begin with describing the problem. Your doctor may ask questions such as:
How often do you go to the bathroom?
When you go to the bathroom, do you have trouble starting or stopping the flow of urine?
Do you leak urine during certain activities?
Do you leak constantly?
Do you leak urine before you get to the bathroom?
Do you experience pain or burning when you urinate?
Do you get frequent urinary tract infections?
Have you had a back injury?
Do you have a medical condition that could interfere with bladder function?
What medications are you taking?
Next, your doctor will perform a physical examination and look for signs of damage to the nerves that affect the bladder and rectum. Depending on the findings of the examination, your doctor may refer you to a urologist (a doctor who specializes in diseases of the urinary tract) or neurologist (a doctor who specializes in diagnosing and treating diseases of the nervous system).
Tests are often needed. These may include:
Bladder stress test. Your doctor checks to see if you lose urine when coughing.
Q-tip test. The doctor inserts a cotton swab into the urethra and has you cough and strain. Excessive movement of the swab could mean weakening of the tissues that support the bladder.
Catheterization. After having you go to the bathroom and empty your bladder, the doctor inserts a catheter to see if more urine comes out. A bladder that doesn't empty completely could indicate overflow incontinence.
Urinalysis and urine culture. Lab technicians check your urine for infection, other abnormalities, or evidence of kidney stones.
Ultrasound. An imaging test is performed to visualize inner organs such as the bladder, kidneys, and ureters.
If the diagnosis is still not clear, your doctor may order urodynamic testing. Urodynamic testing can evaluate bladder contractions, bladder pressure, urine flow, nerve signals, and leakage.
Other tests to confirm a diagnosis may include: cystocopy, a test that examines the inside of the bladder with a small scope called a cytoscope; and IVP, a procedure in which a special solution is injected into a vein in your arm and an X-ray is taken of your kidneys, ureters (the tubes that carry urine from the kidneys to the bladder), and bladder.
