Uropathogens and Gestational Outcomes of Urinary Tract Infections in Pregnancies that Necessitate Hospitalization

Abstract

Background and Objectives: Our aim is to identify uropathogens that cause urinary tract infections (UTIs) that necessitate hospitalization, and analyze outcomes of gestational UTIs. Methods: This study consisted of 30 pregnant women who necessitate hospitalization because of UTI (7.8% of gestational UTIs during the same period of time). UTI that necessitates hospitalization is defined as clinical complaints, urination problems, urine analysis and culture positivity, fever and uterine discomfort. Patients with at least two positive cultures (≥ 100,000 cfu/ml) were included to this study. Antimicrobial susceptibility tests were obtained in all cases in order to determine antimicrobial resistance and to choose the ideal antibiotics for treatment. Results: In our study, we have found that Escherichia coli is the most common microorganism (56.7%). Enterococcus faecalis (13.3%) and Klebsiella pneumonia (10%) were other frequently observed microorganisms. In this series, mean gestational week at birth was 35 weeks 5 days (range 23-40 weeks). Mean birthweight was 2,656 g (range 500-3,700 g). Twenty-three cases (76.7%) were hospitalized before 37th gestational week and preterm delivery rate was 56.3%. Maternal risk factors and coexisting diseases were detected in 11 (36.7%) patients as follows: diabetes mellitus in 4, thrombophilia in 3, thyroid disorders in 3 and hydroureteronephrosis in 1 case. Cesarean section rate was 65.2%. Conclusions: Knowing uropathogens of patient population is beneficial in the management of patients and better planning of future medical treatments. Preterm labor seems to be an important complication in pregnancies with UTIs going together with fever and urination problems.
