Urinary tract infections are quite common. A urinary tract infection is an infection of any part of the urinary tract: the kidneys, ureters, bladder, and urethra. Women are more likely to get urinary tract infections than men, however both men and women can be affected. Women have a shorter urethra than men and therefore has a shorter distance for bacteria to reach the bladder. Sexual activity can also increase the risk of contracting a urinary tract infection. Urinary tract infections are most commonly seen in the lower part of the urinary tract, the urethra and bladder. These infections occur when bacteria enters the urinary tract and proliferates. Symptoms of urinary tract infections include: strong urgency to urinate, frequent urination, passing small amounts of urine, discolored urine, strong smelling urine, and pelvic pain. Urinary tract infections may have more specific signs and symptoms depending on the area of the urinary tract that is affected. Typical biomedical treatment of urinary tract infections includes a course of antibiotics.
