Abstract
Pattern of bacteria that causes urinary tract infection (UTI) in infants after discharge
from neonatal intensive care units (NICU) are not well described. This Study included
74 patients with first episodes of UTI in the first 3 months of life. They were divided
into 2 groups, 31 case occurred during NICU stay (group 1), 43 cases with UTI that
occurred after discharge from NICU (group 2, NICU graduates). Types of bacteria, its
susceptibility to common antibiotics, renal abnormalities and circumcision status
were compared between both groups. Eighty two percent of patients in the both groups
were male. Between 71.9%–74.4% of patients in both groups were preterm. Among NICU
graduates, Incidence of UTI in infants who were preterm and those who were term was
8.2% and 2.1% respectively p < 0.001. The most common causative bacteria in both groups were Klebsiella pneumoniae
and Escherichia coli. Bacteria that caused UTI in NICU graduates were highly resistant
to common antibiotics and were similar (in types and the resistance) to bacteria that
caused UTI in patients during stay in NICU. UTI in NICU graduates happen frequently
in premature, young male infants. Their UTI were caused by bacteria that are similar
in type and resistant pattern to those cause UTI in NICU patients.
