patient profiles

Certain risk factors have been identified on the basis of age, sexual activity and medical history:


Half of all women experience a UTI, and 1 in 10 have three or more a year


Reduced estrogen changes the urinary tract and makes it more vulnerable


Bacteria can enter the urethra during intercourse


Diaphragms and some spermidical agents may increase the risk


Recurrent UTIs are associated with pyelonephritis, veriscoureteral reflux and asymptomatic bacteriuria


Kidney stones (or an enlarged prostate) or any other urinary tract blockage can prevent the bladder from flushing out harmful bacteria

medical conditions

Diabetes and other conditions that may slow or stop the body from fighting infection increases risk

catheter use/SCI

Using catheters to urinate – for instance, when hospitalized, paralyzed or dealing with neurological problems – may lead to UTIs
