Abstract

There had been total 165 cases of urinary tract infection who had been admitted to the ward of pediatrics, National Medical Center from ]an. 1986 to Sept. 1987. Among these, 80 cases had indication of radiologic evaluation; they were the first-documented urinary tract infection in male patients, the first documented urinary tract infection in female patients younger than 6 years of age, the first infection presenting as severe clinical pyelonephritis and the second infection in girls. In 80 cases, ultrasound and voiding cystourethrography were performed. Intravenous pyelopraphy was performed only when there had been any abnormality in above two studies. Among these, 37 patients were neonates and total male to female ratio was 1:0.6. Abnormal finding of ultrasound were noted in 26 cases (32.5%), which were hydronephrosis and/ or hydroureter in 10 cases, calyx or pelvic dilatation in 8 cases, focal or diffuse enlargement in 5 cases. Chronic pyelonephritis with renal scarring in 3 cases and renal abscess in 2 cases. Vesicoureteral reflux finding in voiding cystourethrography were noted in 12 cases (15%) and there were noted the grade 1 reflux in 3 cases, grade 11 in 1 case, grade III in 4 cases, grade IV in 2 cases ad grade V in 2 cases Abnormal findings in intravenous pyelography were noted in 11 cases μ4.4%) with a leading one of hydronephrosis and/ or hydroureter in 7 cases, chronic pyelonephritis with scarring in 2 cases, calyx or pelvic dilatation in 1 cases and mass in 1 case. Associated urinary tract abnormality were noted in 9 cases and abnormalities were detected more by intravenous pyelography than ultrasonography. Abnormal findings as Iike hydronephrosis and/ or hydroureter, renal scarring calyx or pelvic dilatation, renal abscess were detected more by ultrasonography than intravenous pyelography. It was concluded that ultrasonography could successfully replace intravenous pyelography as a screening imaging procedure for the urinary system. And intravenous pyelography was needed only when uItrasonography and/or cystourethrography results were abnormal.
