title: Maternal urinary tract infection as a risk factor for neonatal urinary tract infection.
abstract: BACKGROUND
  The aim of the present study was to evaluate the association of maternal UTI during pregnancy with neonatal UTI.
  
  
  METHODS
  One hundred and fourteen neonates admitted to hospital were enrolled in the present study, of whom 40 were admitted for management of UTI and 74 for management of jaundice. Urinalysis and urine culture were carried out for all of the neonates. Data regarding gestational age, history of UTI in the mother during pregnancy, and urinary symptoms of neonates were collected.
  
  
  RESULTS
  The mean gestational age of the neonates was 38.4 ± 1.4 weeks (range, 30 to 40 weeks) and their mean age at admission was 6.2 ± 3.8 days old (range, 1 to 25 days). The mean gestational age and birth weight of the two groups with and without UTI were 38.38 ± 1.32 weeks versus 38.41 ± 1.62 weeks and 2930.43 ± 492.15 g versus 2930 ± 447.33 g, respectively. No abnormal findings were detected on physical examinations, and none of the neonate had abnormal renal ultrasonography findings. There was a significant relationship between maternal prenatal UTI and neonatal infection; 30.0% of the neonates with UTI versus 6.8% of those without UTI had mothers with a history of UTI (odds ratio, 5.9; 95% confidence interval, 1.9 to 18.3; P = .001).
  
  
  CONCLUSIONS
  Our study showed an association between maternal and neonatal UTI. This indicates a possible benefit of evaluation of neonates of mothers who had UTI during pregnancy.
