Michael Roizen, MD, Internal Medicine, answeredUrinary tract infections (UTIs) are triggered by bacteria (and sometimes fungi and viruses). The old thinking was this: bugs enter the urethra (the tube that urine goes through) and colonize the bladder and kidney after sex or—for women—if you wipe wrong. It's true that those things can trigger UTIs, but both good and bacteria live in your bladder all the time. We don't really know what's going on in there, so the real remedy is prevention.

Bacteria, a type of germ that gets into your urinary tract, cause a UTI. This can happen in many ways:Wiping from back to front after a bowel movement (BM). Germs can get into your urethra, which has its opening in front of the vagina. Having sexual intercourse. Germs in the vagina can be pushed into the urethra. Waiting too long to pass urine. When urine stays in the bladder for a long time, more germs are made, and the worse a UTI can become. Using a diaphragm for birth control, or spermicides (creams that kill sperm) with a diaphragm or on a condom Anything that makes it hard to completely empty your bladder, like a kidney stone. Having diabetes, which makes it harder for your body to fight other health problems. Loss of estrogen (a hormone) and changes in the vagina after menopause. Menopause is when you stop getting your period. Having had a catheter in place. A catheter is a thin tube put through the urethra into the bladder. It's used to drain urine during a medical test and for people who cannot pass urine on their own.

Women who are sexually active are susceptible to urinary tract infection (UTI). Women have a short urethra (the tube between the bladder that allows flow of urine out of the body). This makes it easier for skin and fecal bacteria to make their way up into the bladder especially with sexual activity.
Those who use a diaphragm, spermicide foam, or have partners who use condoms for birth control also are at increased risk of infection.
As women age, the urinary tract thins and this too can increase the chance of infection. In addition, loss of estrogen reduces the ability of the vagina to block bacteria from entering. Finally, women with skin allergies are at increased risk for UTI.

More than 90 percent of all UTIs are caused by Escherichia coli (E. coli), which is normally found in your intestinal tract. Problems only arise when this ordinary bacterium is present in high numbers in places where it shouldn’t be—like your urinary system.
It should be noted that this is NOT the same E. coli associated with killer outbreaks in unsanitary food processing plants—that is a mutant variety, probably created by antibiotic overuse in our country. This E.coli is typically a normal part of your gut flora and typically is accidentally transferred to the bladder through lapses in optimal hygiene.
When normal E. coli gets into your urinary tract and multiplies, you experience the usual signs and symptoms of a UTI:
- Burning with urination
- Frequent urges to urinate
- Lower abdominal pain or aching
- Blood in your urine (sometimes, but not always)
- Cloudy urine
Bacteria that enter the urethra and travel up the urinary tract are the usual cause of urinary tract infections (UTIs). Bacteria that normally live in the large intestine and are present in feces (stool) are the most common source of infection. Sexual intercourse may move bacteria into the urinary tract, especially in women. Catheters, which are small, flexible tubes inserted into the bladder to allow urine to drain, are a common source of bacterial infection in people who are in hospitals or who live in long-term care facilities.
Sometimes bacteria traveling through the blood or lymph system cause kidney or bladder infections.
Kidney stones, an enlarged prostate in men, and structural problems in the urinary tract can contribute to UTIs by limiting the body's ability to eliminate urine completely.

Most urinary tract infections are caused by the E. coli bacterium. Many factors are associated with increased risk of urinary tract infections (UTI): pregnancy (twice as frequent); menopause; sexual intercourse (nuns have one tenth the incidence); mechanical trauma or irritation; and, perhaps most important, structural abnormalities of the urinary tract that block the free flow of urine, such as benign prostatic hyperplasia in men.

Urinary tract infections are caused by bacteria that occur in fecal material. This is the reason why women are told to wipe from "front to back". The most common bacteria seen in a urinary tract infection is E. coli, and this is also commonly seen in feces. Urinary tract infections can be caused by sexual intercourse, waiting too long to urinate, inadequate bladder emptying, and some forms of birth control such as spermicidal jelly and the use of diaphragms. There are medical problems that can increase the risk of urinary tract infections, and the most common is diabetes. Diabetic patients can have inadequate bladder emptying and chronically have high residual volumes of urine in their bladder. Lastly, women who go through menopause and have a lack of estrogen in the vaginal tissue can have an increased risk of bladder infections. The reason is that there are numerous estrogen receptors in the vagina, and a lack of estrogen can cause the vaginal tissue to become atrophic or dry, and this can cause the increase in bacteria from the rectum to flourish in the vagina and then it is very easy for the bacteria to go from the vagina to the urethra causing a bladder infection.
