[Sonographic renal diagnosis in paediatrics (author's transl)].

Sonography is a method without risk but of high diagnostic value. Hence, it is extremely well suited for paediatric examination. In our opinion, this method should rank first among all other examination methods when clarifying inflammatory conditions of kidneys and of the efferent urinary tract, whereas in all other problems sonography continues to rank second behind the urogram. Both examinations together, which account for a diagnostic safety of more than 95%, are employed to decide whether and to what extent other and more invasive and complicated measures will have to be taken.
