Escherichia coli is the most common cause of uncomplicated UTI and accounts for approximately 75 to 95 percent of all infections. 2 - 5 A longitudinal study 6 of 235 women with 1,018 UTIs found that E. coli was the only causative agent in 69.3 percent of cases and was a contributing agent in an additional 2.4 percent of cases. Staphylococcus saprophyticus is a distant second, accounting for only 5 to 20 percent of infections. Other Enterobacteriaceae, such as Klebsiella and Proteus, occasionally cause UTI. 2, 3, 5 Although S. saprophyticus is less common than E. coli, it is more aggressive. Approximately one half of patients infected with S. saprophyticus present with upper urinary tract involvement, and these patients are more likely to have recurrent infection. 3

Uncomplicated UTI occurs in patients who have a normal, unobstructed genitourinary tract, who have no history of recent instrumentation, and whose symptoms are confined to the lower urinary tract. Uncomplicated UTIs are most common in young, sexually active women.
