Radiological findings in newborn infants with urinary infection.

Selective suprapubic urine aspiration was performed in 905 of 12 942 consecutive live-born infants and showed the presence of infection in 64 (0-5%). A majority (84%) of the infected infants were males. Radiological abnormalities were detected in 35 (55%). Because of this high incidence of abnormalities, which when diagnosed might alter management, it is suggested that radiological investigations be performed in newborn infants with proven urinary infection.
