Abstract

Clinical studies on the 96 cases of urinary tract infection who were admitted to the pediatric depart- ment of Severance Hospital from Jan. 1978 to Dec. l981 were subjected in this study. The results were as follows: 1. The incidental ratio to total inpatients was 0. 7%, and difference of annual incidence was not remarkable. 2. Seasonal difference and monthly distribution were not significant. 8. Age incidence disclosed under l year in 19 cases (19.8;), 1 to 6 year in 43 cases(44.8%), 7 to 12 years in 30 cases(31.3%) and 6 year in 43 cases (44.8%), 7 to 12 years in 30 cases (31.3%) and above 13 years in 4 cases (4.1.%). 4. Thirty-eight cases(39. 6% ) were male and 58 cases(60.4,p) were fema]e with male to female ratio of I: 1. 5. Under one year of age, male(12 cases) was more commonly affected than the female(7 cases). 6. Fever was the most common chief complaint and hematuria, vomiting, urinary frequency and flank pain were also common. In infants, nonspecific symptoms such as fever, vomiting, failure to thrive and jaundice were more common, but in the patients above one year of age, urinary symptoms such as hemat.uria, urinary frequency, dysuria and turbid urine were more common. 6. Urinalysis disclosed pyuria in 67 cases(69.8 hematuria in 56 cases(58. 3/) and proteinuria in 36 cases(37.5%).7.Hematologic findings showed low hemoglobin in 24.0% leukocytosis in 28.1%, elevated ESR In 40.4%, positive CRP in 55% and BUN over 20 mg/ dl in 10. 7%. 8. Relation between pyuria and colony count sho- wed significant bacteriuria with WBC >_20/HPF on rinalysis was most common(34 cases, 35.4%). However, 29 cases(30.4%) without pyuria showed significant bacteriuria. 9. Esc herichia coli was the most common stram (44 cases, 56.4%) and Zlebsiella species, Slaphy- lococcus aureus, EnlerococcIis were common in des- cending order. 10. The sensitivity test showed Escherichia coli was sensitive to gentamicin, cephalothin and ami- kacin. 11. Intravenous pyelography was performed in 74 cases, and 44 cases(59.5%) of them showed abnor- mal findings such as double collecting system, hy- dronephrosis and/or hydroureter, poor visualization of kidney and renal scarring. 12. Voiding cystourethrography findings in 33 cases showed vesicoureteral reflux in 16 cases (48.5g).
