Nephrolithiasis is unusual in North American children and rare in newborn infants. We recently diagnosed nephrolithiasis in two premature infants who were on long-term furosemide therapy because of severe bronchopulmonary dysplasia. In both cases, the calculi were incidental findings on routine abdominal radiographs. Portable sonography was used in both infants to confirm the intrarenal location of the calculi and to exclude hydronephrosis.
