Abstract

Urinary tract infection (UTI) represents the most common genitourinary disease in children and are the second most common infection in children. Besides, they are potentially dangerous not only because may present as life-threatening episodes with serious prognosis, but also because may be the forerunners of severe renal disease of adulthood. So the importance at early diagnosis and investigation of apparently uncomplicated UTI should also be recognized so that the development of later damage can be prevented by suitable therapy. We studied 158 cases of UTI who were admitted to the Department of Pediatrics, Hanyang University Hospital from January 1978 to April 1983. The results were as follows: 1)Age incidence disclosed under 1 month in 8 cases(5%), 1 month to 1 year in 44 cases (28%), 1 to 6 years in 56 cases(35%), 6 to 10 years in 7 cases(17%), and above 10 years in 23 case(15%). 2) Sex incidence shows male predominence with male to female ratio of 1.4 : 1. 3)Chief complaints on admission were in the order of fever、gastrointestinal symptoms, irritability, pallor etc. 4)E.coli was the most common organism (83 cases, 49%) and Klebsiellae, Enterococci, and Enterobacter were common in descending order. In the complicated group with abnormal radiologic findings, incidence of E.coli(28%) was decreased while Klebsillae(20%) and Proteus (13%) were increased. 5)Incidence of radiological abnormalities was 55% in over-all and similar in both sexes (male; 53%, female; 65%). Most common abnormality was vesicoureteral reflux(10 cases) and clubbing and/or scarring, hydronephrosis and/or hydroureter, transverse defect, dilated ureter, and dilated caliopelvic system were common in descending order. 6)In follow up study, recurrence rate was 53% in the group which has radiological abnornality and 50% in no abnormality. 7)Changes of radiologic finding were detected in 8 cases. We found disappearance of vesicoureteral reflux in 4 cases, bladder diverticulum in 1 case and decreased degree of hydronephrosis and pelvicalyceal dilatation in 1 case, respectively. But renal damages are slightly progressed in 4 cases.
