Clinical, bacteriologic and radiologic studies were performed in 63 infants and children with urinary tract infection who were admitted to Department of Padiatrics, Pusan National University Hospital from March 1982 to February 1988. The results were summarized as follows: 1) UTI was more prevalent in infancy and early childhood (71.4%). Sex distribution was similar in all age group, and male was more prevalent in infancy and female was more prevalent thereafter, but no statistical significance. 2) Fever was the most common manifestation. Systemic manifestations such as irritability and poor feeding were predominant in the infancy and early childhood whereas local manifestations such as dysuria, frequency in urination and abdominal pain were predominant in the late childhood. 3) Hematologic findings showed leukocytosis (white blood cell, 15,000 /mm3 or more) in 68.2% and anemia (hemoglobin, 10gm/dl or less) in 9.5%. Urinalysis findings showed proteinuria in 53.9%, hematuria in 33.3% and pyuria in 88.9%. 4) E. coli was the most prominent strain, cultured in 50.7%. Others included Klebsiella,Proteus and enterococcus in order. The incidence of UTI by E. coli was higher in infancy (76.5%) than in thereafter (43,1) and female (64.7%) than male (39.1%). Patients associated with radiologic abnor- malities had lower incidence of E. coli (16.0%) than others (68.0%). They showed the predominance of Serratia, coagulase positive Staphylococcus. 5) There was abnormal findings on radiologic studies (IVP, VCUG, DMSA scan etc) in 16 cases of patients (59.3%). Vesicoureteral reflux was the most common abnormal finding of them (68%). Renal scar and vesicoureteral reflux was more sensitively detected by DMSA renal scan.
