Ultrasonography is an imaging test that is often performed as an initial assessment of pediatric renal and urinary tract disease, and sometimes ultrasonography has the accuracy of a detailed test. In many cases, however, newborns and infants must be tested in situations where cooperation is not available. Even in such a situation, in order to obtain useful information for differential diagnosis, it is important that the examiner has a good understanding of child-specific disease concepts such as renal malposition, renal dysplasia, fused kidney, renal cystic lesions, renal tumors, congenital anomalies of the kidney and urinary tract, hydronephrosis, and urinary tract infections. In addition, children often have less time to rest than adults, so it is desirable to finish the test in the shortest possible time. For that purpose, it is important to observe promptly from the point with the highest priority and record highly objective images.
