Abstract
Uninary tract infection as one of the common infectious disease all through the childhood and can be the cause of febrile illnesses. During infancy, the diagnosis of UTI is easily overooked because of relative lack of charateristic urinary symptoms. But UTI was found to cause longterm sequelae more often in infancy than later. We studied 258 cases of febrile infants and 345 cases of afebrile infants under the 2 years of age in the pediatric ward and outpatient clinic, from March 1985 to June 1986 to determine the incidence of UTI in those infants The results were as follows; 1) The numbers of UTI were 16 cases in 258 febrile infants (6.2%) and 6 cases in 345 afebrile infants (1.7%), which reveals the significance of fever in incidence of UTI of infants without urinary symptoms. 2) The incidence of UTI in cases with urinary symptoms was not statistically different between febrile (50%) and afebrile infants (31.3%), and higher than that in cases without urinary symptom regardless of the presence of fever. 3) The rate of UTI in infants with abnormalities in routine urinalysis was higher than that in cases with normal urinalysis regardless of the presence of fever. 4) Higher the rate of UTI was longer the duration of fever was. 5) Age incidence was more common within 1 year of age (74.3%) than that in 1 to 2 year of age (25. 7%). Sex incidence revealed male predominance regardless of age. 6) Radiological abnormalities in IVP, VCUG were seen in 8 cases (23%) among 35 es of UTI. VUR was the most common abnormality (5 cases) and each one case of UPJ stenosis. VUJ stone and diverticulum of bladder were found. 7) Rate of VUR was 11 % (3 cases of 24 cases) in febrile UTI, 18% (2 ca s of 11 cases) in afebrile UTI and the difference was not significant.
