BACKGROUND: The urinary tract infections in pregnant women are the second most frequent medical pathology in pregnancy, presenting an incidence of 5-10%. In Mexico, according to the Mexican Clinical Practice Guide, the incidence is 2%, and establishes a recurrence of 23% of them. OBJECTIVE: To determine the associated epidemiologic factors with recurring infections in lower urinary tract in pregnant women during the period of May 2019 through May 2020. MATERIAL AND METHODS: Analytical observational cross-sectional and retrospective research study, where prena-tal control sheets of clinical records were reviewed from the institutional program to identify frequency of recurrence and epidemiologic factors associated with lower uri-nary tract infections in 90 pregnant women; the variables were analyzed through de-scriptive statistics and analytical statistics. RESULTS: Of a total of 90 electronic records of pregnant women, a recurrence of lower urinary tract infections was found in 41 patients (45.6%), in whom we didn’t found association with the studied factors. CONCLUSIONS: The prevalence of recurring lower urinary tract infections during pregnancy in our pop-ulation is alarming in whom no association was found with the presence of the epide-miologic factors studied in the present investigation; however, a tendency of recurrence urinary tract infections was identified in women that are not working, superior level of education, 2 pregnancies or less, patients under 20 years of age and in those who were treated with nitrofurantoin for a period of time less than 7 days.
