Sažetak
In order to investigate the value of renal ultrasonography (RUS) consecutive cases of 331 children (108 boys, 223 girls), mean age 3.05 years were examined within 3 days of admission. The first urinary infection was culture-documented in all. On clinical bases 61% of patients had acute pyelonephritis; 20% of patients had previous undiagnosed urinary infection. Cystography, intravenous urography and dynamic scintigraphy 99m Tc MAG3 undertaken within 3 months of admission followed RUS. The objective was to evaluate the presence of inflammatory changes and structural anomalies by RUS compared to other techniques. By all imaging procedures anomalies were detected in 167 patients (50%): vesicoureteral reflux in 142 (43%), obstructive anomalies in 14 (4%) and other anomalies in 11 (3%). RUS was normal in 56% of patients. Inflammatory changes had 27% of all studied, but 40% of patients with acute pyelonephritis. Structural anomalies (pyelon dilatation or anomalies) had 17% of studied patients most infants (p<0.01) RUS in combination with voiding cystography identified almost all patients with anomalies (sensitivity 98%, accuracy 83%). RUS was in agreement with other techniques concerning obstructive and other anomalies except for acute inflammatory changes present in 77% and renal scaring in 33% of patients evaluated by MAG3. Conclusions. RUS with voiding cystography in younger patients with first urinary infection will identify any anomaly of clinical importance. RUS as less effective in identifying inflammatory changes should be followed by renal scintigraphy in any patient with acute pyelonephritis.
