Causes
Cystitis is caused by germs, usually bacteria that enter the
urethra and then the bladder. These bacteria can lead to infection, most
commonly in the bladder. The infection can spread to the kidneys.
Most of the time, your body can get rid of these bacteria
when you urinate. However, sometimes the bacteria can stick to the wall of the
urethra or bladder, or grow so fast that some bacteria stay in the bladder.
Women tend to get infections more often than men because
their urethra is shorter and closer to the anus. For this reason, women are
more likely to get an infection after sexual intercourse or when using a
diaphragm for birth control. Menopause also increases the risk for a urinary
tract infection.
The following also increase your chances of developing cystitis:
- A tube called a urinary catheter inserted in your bladder
- Blockage of the bladder or urethra
- Diabetes
- Enlarged prostate, narrowed urethra, or anything that blocks the flow of urine
- Loss of bowel control (bowel incontinence)
- Older age (especially in people who live in nursing homes)
- Pregnancy
- Problems fully emptying your bladder (urinary retention)
- Procedures that involve the urinary tract
- Staying still (immobile) for a long period of time (for example, when you are recovering from a hip fracture
- Most cases are caused by Escherichia coli (E. coli), a type of bacteria found in the intestines.
Symptoms
- The symptoms of a bladder infection include:
- Cloudy or bloody urine, which may have a foul or strong odor
- Low fever (not everyone will have a fever)
- Pain or burning with urination
- Pressure or cramping in the lower abdomen (usually middle) or back
- Strong need to urinate often, even right after the bladder has been emptied
- Often in an elderly person, mental changes or confusion are the only signs of a possible urinary tract infection.
Exams and Tests
- A urine sample is usually collected to perform the following tests:
- Urinalysis is done to look for white blood cells, red blood cells, bacteria, and to test for certain chemicals, such as nitrites in the urine. Most of the time, your doctor or nurse can diagnose an infection using a urinalysis.
- Urine culture - clean catch may be done to identify the bacteria in the urine to make sure the correct antibiotic is being used for treatment.
Treatment
- Antibiotics taken by mouth are usually recommended because there is a risk that the infection can spread to the kidneys.
- For a simple bladder infection, you will take antibiotics for 3 days (women) or 7 - 14 days (men). For a bladder infection with complications such as pregnancy or diabetes, OR a mild kidney infection, you will usually take antibiotics for 7 - 14 days.
- It is important that you finish all the antibiotics, even if you feel better. People who do not finish their antibiotics may develop an infection that is harder to treat.
- Commonly used antibiotics include trimethoprim-sulfamethoxazole, amoxicillin, Augmentin, doxycycline, and fluoroquinolones. Your doctor will also want to know whether you are pregnant.
- Your doctor may also recommend drugs to relieve the burning pain and urgent need to urinate. Phenazopyridine hydrochloride (Pyridium) is the most common of this type of drug. You will still need to take antibiotics.
- Everyone with a bladder or kidney infection should drink plenty of water.
- Some women have repeat or recurrent bladder infections. Your doctor may suggest several different ways of treating these.
- Taking a single dose of an antibiotic after sexual contact may prevent these infections, which occur after sexual activity.
- Some women may need to have a 3-day course of antibiotics at home to use for infections, based on their symptoms.
- Some women may also try taking a single, daily dose of an antibiotic to prevent infections.
- Over-the-counter products that increase acid in the urine, such as ascorbic acid or cranberry juice, may be recommended to decrease the concentration of bacteria in the urine.
- Follow-up may include urine cultures to make sure the bacterial infection is gone.
Outlook (Prognosis)
- Most cases of cystitis are uncomfortable, but go away without complications after treatment.
Prevention
- Lifestyle changes may help prevent some urinary tract infections.
- After menopause, a woman may use estrogen cream in the vagina area to reduce the chance of getting further infections.
Bathing and Hygiene
- Choose sanitary pads instead of tampons, which some doctors believe make infections more likely. Change the pad each time you use the bathroom.
- Do not douche or use feminine hygiene sprays or powders. As a general rule, do not use any product containing perfumes in the genital area.
- Take showers instead of baths. Avoid bath oils.
- Keep your genital area clean. Clean your genital and anal areas before and after sexual activity.
- Urinate before and after sexual activity.
- Wipe from front to back after using the bathroom.
Clothing
- Avoid tight-fitting pants.
- Wear cotton-cloth underwear and pantyhose, and change both at least once a day.
Diet
- Drink plenty of fluids (2 to 4 quarts each day).
- Drink cranberry juice or use cranberry tablets, but NOT if you have a personal or family history of kidney stones.
- Do NOT drink fluids that irritate the bladder, such as alcohol and caffeine.
- Urinating immediately after sexual intercourse may help remove any bacteria that may have gotten in during intercourse. If you do not urinate for a long period of time, the bacteria have time to multiply. Frequent urinating may reduce the risk of cystitis in those who are prone to urinary tract infections.
