Objective. Little is known regarding the prevalence of early postpartum bacteriuria. We sought to evaluate the incidence of bacteriuria following labor and to identify risk factors predisposing to this condition. Methods. Three hundred and fifty parturients were recruited, 301 were included in the analysis. Women receiving antibiotic drugs during delivery were excluded. Urine cultures were obtained from the study group before delivery and prior to discharge. Data regarding management of labor was collected prospectively. Results. Positive urine cultures were present on admission in 5.4% of women, whereas 12.9% had a positive urine culture at discharge (p < 0.003). Bacteriuria was acquired during labor in 12.7% of patients who had negative cultures on admission. Escalating number of digital vaginal examinations (p = 0.04), recurrent bladder catheterization (p = 0.05), duration of epidural anesthesia (p = 0.002), and vacuum delivery (p = 0.02) correlated significantly with an increased risk for acquiring bacteriuria. Conclusion. Labor is a bacteriuric event. Iatrogenic interventions can predispose parturients with sterile urine cultures to postpartum bacteriuria.
