[Nephro-urologic ultrasound diagnosis in the child]

The most common and characteristic abnormalities of the child's kidneys and urinary tract and the pertinent modalities of diagnostic imaging are briefly discussed. In this context, ultrasonography (US) is the basic imaging tool. Its advantages and limits are exposed. A wide spectrum of anatomic parameters can be demonstrated by US, while functional aspects must be evaluated by complementary methods in order to complete the diagnostic work-up. Voiding cystourethrography and scintigraphy are excellent means in the evaluation of the child's urinary tract and should both be performed by experts in order to combine a maximum of diagnostic information with minimal invasiveness.--Some technical aspects regarding the child's specific clinical condition and the involved imaging methods are mentioned.
