Risk factors discussion:

Urinary Tract Infections in Adults: NIDDK (Excerpt)

Some people are more prone to getting a UTI than others. Any abnormality of the urinary tract that obstructs the flow of urine (a kidney stone, for example) sets the stage for an infection. An enlarged prostate gland also can slow the flow of urine, thus raising the risk of infection.

A common source of infection is catheters, or tubes, placed in the bladder. A person who cannot void or who is unconscious or critically ill often needs a catheter that stays in place for a long time. Some people, especially the elderly or those with nervous system disorders who lose bladder control, may need a catheter for life. Bacteria on the catheter can infect the bladder, so hospital staff take special care to keep the catheter sterile and remove it as soon as possible.

People with diabetes have a higher risk of a UTI because of changes in the immune system. Any disorder that suppresses the immune system raises the risk of a urinary infection.

UTIs may occur in infants who are born with abnormalities of the urinary tract, which sometimes need to be corrected with surgery. UTIs are rarely seen in boys and young men. In women, though, the rate of UTIs gradually increases with age. Scientists are not sure why women have more urinary infections than men. One factor may be that a woman's urethra is short, allowing bacteria quick access to the bladder. Also, a woman's urethral opening is near sources of bacteria from the anus and vagina. For many women, sexual intercourse seems to trigger an infection, although the reasons for this linkage are unclear.

According to several studies, women who use a diaphragm are more likely to develop a UTI than women who use other forms of birth control. Recently, researchers found that women whose partners use a condom with spermicidal foam also tend to have growth of E. coli bacteria in the vagina.

Urinary Tract Infections: NWHIC (Excerpt)

Some people are more prone to getting a UTI than others. Any abnormality of the urinary tract that obstructs the flow of urine (a kidney stone, for example) sets the stage for an infection. A common source of infection is catheters, or tubes placed in the bladder to aid in urination for people unconscious or critically ill. Bacteria on the catheter can infect the bladder, so hospital staff take special care to keep the catheter sterile and to remove it as soon as possible. People with diabetes have a higher risk of a UTI because of changes in the immune system. Any disorder that suppresses the immune system raises the risk of a urinary infection. Women may have more urinary infections than men because the womanís urethra is relatively short, allowing bacteria quicker access to the bladder. Further, a womanís urethral opening is near sources of bacteria from the anus and vagina. One in five women develops a UTI during her lifetime. For many women, sexual intercourse seems to trigger an infection, although the reasons for this linkage are unclear. According to several studies, women who use a diaphragm are more likely to develop a UTI than women who use other forms of birth control. In addition, women whose partners use condoms tend to have growth of E. coli bacteria in the vagina, which may increase the risk of a UTI. Further, in women, the rate of UTIs gradually increases with age. (Source: excerpt from Urinary Tract Infections: NWHIC)

About risk factors:

Risk factors for Urinary tract infections are factors that do not seem to be a direct cause of the disease, but seem to be associated in some way. Having a risk factor for Urinary tract infections makes the chances of getting a condition higher but does not always lead to Urinary tract infections. Also, the absence of any risk factors or having a protective factor does not necessarily guard you against getting Urinary tract infections. For general information and a list of risk factors, see the risk center.
