Abstract

Background: When there is considerable bacteriuria present but no signs of a urinary tract infection [UTI], this condition is known as asymptomatic bacteriuria [ASB]. In 2-10% of pregnant women, ASB occurs, which may be associated with adverse maternal and neonatal outcomes. The current work aimed to study the association between asymptomatic bacteriuria at term pregnancy and the various maternal and neonatal outcomes
Patients and Methods: A prospective observational study included 100 pregnant women at gestational age between 37 to 40 weeks. Urine culture was analyzed for all women, followed by follow-up for reporting adverse maternal and neonatal outcomes.
Results: The frequency of cases with ASB was 24%. ASB was significantly associated with preterm labor [33.3% and 19.7% among positive culture and negative culture groups, respectively; P=0.021]. The percentage of PROM among the mothers with positive culture was higher as compared with the negative culture group [20.8% and 15.8%, respectively], but, no statistically considerable value was reached [p=0.280]. Neonates born to mothers with ASB had significantly lower birth weights [P=<0.001] and 5-min Apgar scores [P=0.024].
Conclusion: Asymptomatic bacteriuria was frequent among women at term pregnancy in the current study. It was associated with preterm labour, low birth weight and decreased 5-min Apgar score at birth, Further studies are needed.
