The objective of the study was to determine the value of spiral computerized tomography (CT) in detecting urolithiasis in pediatric patients and compare its efficacy with ultrasound (US). Twenty-nine infants aged between 2 to 94 months with clinical presentation suggestive of urolithiasis and a negative or indeterminate plain film were included in the study. Abdominal US and spiral CT were performed in all patients. ⋯ US was able to localize 31 stones (68.8%) in 21 kidneys (75%), and 3 stones (25%) in 11 ureters (27.2%). Spiral CT is very effective in the diagnosis of pediatric urolithiasis. Spiral CT is more efficient than US in imaging pediatric patients with symptoms and signs of urolithiasis, when KUB is inconclusive.
