Women And Diabetic Complications - What is a urinary tract infection (UTI)?

A UTI is an infection anywhere in the urinary tract. Your urinary tract includes the organs that collect and store urine and release it from your body. They are the:

kidneys – collect wastes and extra water from your blood to make urine
ureters – carry the urine from your kidneys to your bladder
bladder – stores the urine and squeezes it out when full
urethra – carries the urine out of your bladder when you urinate
prostate – adds fluid to semen
What causes a UTI?

Usually, a UTI is caused by bacteria that can also live in the digestive tract, in the vagina, or around the urethra, which is at the entrance to the urinary tract. Most often these bacteria enter the urethra and travel to the bladder and kidneys. Usually, your body removes the bacteria, and you have no symptoms. However, some people seem to be prone to infection, including women and older people.

When should I see my doctor?

You should see your doctor if you have any of these signs or symptoms:

burning feeling when you urinate
frequent or intense urges to urinate, even when you have little urine to pass
pain in your back or lower abdomen
cloudy, dark, bloody, or unusual-smelling urine
fever or chills
Women are more likely to get UTIs than men are. When men get UTIs, however, they're often serious and hard to treat. UTIs can be especially dangerous for older people and pregnant women, as well as for those with diabetes and those who have difficulty urinating.

What will happen at the doctor's office?

The doctor may ask you how much fluid you drink, and if you have pain or a burning feeling when you urinate, or if you have difficulty urinating. Women may be asked about the type of birth control they use. You'll need to urinate into a cup so the urine can be tested. In addition, your doctor may need to take pictures of your kidneys with an x ray or ultrasound and look into your bladder with an instrument called a cystoscope.

If you have a UTI, your doctor can look through a microscope and find bacteria in a sample of your urine. If the bacteria are hard to see, the doctor may let them grow for a day or two in a culture. Then the doctor can see exactly which kind of bacteria you have and choose an antibiotic that kills them.

The doctor may use either x rays, sound waves (ultrasound), or CT scan to view your bladder or kidneys. These pictures can show stones, blockage, or swelling. The urethra and bladder can be seen from the inside with a cystoscope, which is a thin tube with lenses like a microscope. The tube is inserted into the urinary tract through the urethra.

How are UTIs treated?

Once it is determined that your symptoms have been caused by an infection, your doctor will prescribe an antibiotic. Antibiotics can kill the bacteria causing the infection. The antibiotic prescribed will depend on the type of bacteria found.

For simple infections, you'll be given 3 days of therapy. For more serious infections, you'll be given a prescription for 7 days or longer. Be sure to follow your instructions carefully and completely. If you have any allergies to drugs, be sure your doctor knows what they are.

Will UTIs come back?

Sometimes. Most healthy women don't have repeat infections. However, about one out of every five women who get a UTI will get another one. Some women get three or more UTIs a year. Men frequently get repeat infections. Anyone who has diabetes or a problem that makes it difficult to urinate may get repeat infections.

If you get repeat infections, talk with your doctor about special treatment plans. Your doctor may refer you to a urologist, a doctor who specializes in urinary problems. Your doctor may have you take antibiotics over a longer period to help prevent repeat infections. Some doctors give patients who get frequent UTIs a supply of antibiotics to be taken at the first sign of infection. Make sure you understand what your doctor tells you about taking the antibiotic and do exactly that.

Men may need to take antibiotics for a longer time. Bacteria can hide deep in prostate tissue. Men shouldn't take their spouse's pills and think they will cure the infection. See a doctor for treatment that fits your needs.

How can I keep from getting more UTIs?

Changing some of your daily habits may help you avoid UTIs.

Drink lots of fluid to flush the bacteria from your system. Water is best. Try for 6 to 8 glasses a day.

Drink cranberry juice or take vitamin C. Both increase the acid in your urine so bacteria can't grow easily. Cranberry juice also makes your bladder wall slippery, so bacteria can't stick to it.

Urinate frequently and go when you first feel the urge. Bacteria can grow when urine stays in the bladder too long.

Urinate shortly after sex. This can flush away bacteria that might have entered your urethra during sex.

After using the toilet, always wipe from front to back, especially after a bowel movement.

Wear cotton underwear and loose-fitting clothes so that air can keep the area dry. Avoid tight-fitting jeans and nylon underwear, which trap moisture and can help bacteria grow.

For women, using a diaphragm or spermicide for birth control can lead to UTIs by increasing bacteria growth. If you have trouble with UTIs, consider modifying your birth control method. Unlubricated condoms or spermicidal condoms increase irritation and help bacteria cause symptoms. Consider switching to lubricated condoms without spermicide or using a nonspermicidal lubricant.
