Urinary tract infection (UTI) is defined as the presence of microbial pathogens in the urinary tract with associated symptoms. Urinary tract infections (UTIs) are common, affect men and women of all ages, and vary dramatically in their presentation and sequelae. They are a common cause of morbidity and can lead to significant mortality. UTIs are one of the most common bacterial infections seen in primary care, second only to infections of the respiratory tract (Pushpalatha 2008). They represent the most common bacterial infection in pregnant and non-pregnant women (Foxman 2002, 2003). Eight million women visit a physician annually for evaluation of UTIs (Schappert 1996) at a direct cost of $659 million (Rosenberg 1999), and aggregate cost of $1.6 billion (Rosenberg 1999; Foxman et al. 2000).
