To evaluate factors associated with recurrent urinary tract infection (UTI) in postmenopausal women, we conducted a case-control study comparing 149 postmenopausal women referred to an infectious diseases outpatient clinic who had a history of recurrent UTI (case patients) with 53 age-matched women without a history of UTI (control patients). Each woman completed a questionnaire providing demographic data, history and clinical characteristics of prior infections, and information regarding risk factors for UTI. In addition, each patient underwent a gynecologic evaluation, renal ultrasound and urine flow studies, and blood group and secretor status testing. Three urologic factors—namely, incontinence (41% of case patients vs. 9.0% of control patients; P < .001), presence of a cystocele (19% vs. 0%; P < .001), and postvoiding residual urine (28% vs. 2.0%; P = .00008)—were all strongly associated with recurrent UTI. Multivariate analysis showed that urinary incontinence (odds ratio [OR], 5.79; 95% confidence interval [CI], 2.05–16.42; P = .0009), a history of UTI before menopause (OR, 4.85; 95% CI, 1.7–13.84; P = .003), and nonsecretor status (OR, 2.9; 95% CI, 1.28–6.25; P = .005) were most strongly associated with recurrent UTI in postmenopausal women. Prospective studies are needed to confirm these observations and to develop approaches for prevention.
