Of 147 young women ages 17-34 with signs, symptoms, and bacteriological evidence of urinary tract infection (UTI), 23 (15.6%) had an infection caused by coagulase-negative Staphylococcus (coag-neg Staph). All patients with coag-neg Staph UTI were sexually active in contrast to 84.7% of those with UTI from other causes (1 tailed, P=.03). The former had a higher rate of vaginal discharge (60.9 vs. 25.8% in the latter group, P=.003), but fewer of them used tampons as menstrual protection or oral contraceptives. A high percentage of women with coag-neg Staph UTI had commenced sexual activity recently, as compared with the rest of the group (P=.03). In a stepwise logistic regression analysis, the only variables that were significantly associated with coag-neg UTI were vaginal discharge and recent onset of sexual activity.
