title: Urinary tract infection in infants less than 2 months of age.
abstract: Ninety-five infants, less than 2 months of age, diagnosed as urinary tract infections, from July 1984 to June 1991, were reviewed. Their urinary cultures, obtained either by suprapubic puncture or via catheterization, all had bacterial colony counts of over 10(5)/ml. In this survey, males predominated (91.6%). Fever and gastrointestinal problems were the two most prevalent signs. E. coli was the most common causative organism, and gentamicin was the most effective antibiotic. Vesicoureteral reflux (VUR), the most common anomaly, was found in one-third (25/76) of patients on voiding cystourethrography, with 20% being high grade (Gr. IV or Gr. V). Eleven cases (11%) had bacteremia, and one case had bacterial meningitis. Sixty-seven cases were followed up in our hospital and seven of them had second infections within a year of their first UTI. The mean period between episodes was less than two months. All these patients had urinary tract anomalies and received oral chemoprophylactic drugs for variable lengths of time. Five of the seven recurrences were caused by resistant bacilli. Continuous oral antibiotic prophylaxis and regular follow-up examinations were the rules of prevention for further infection and future renal impairment. These preventive methods are especially important in young infants with UTI.
