title: [Sonographic diagnosis of urine flow disorders in childhood].
abstract: Sonographic diagnosis of urinary tract obstruction is based upon morphological and morphometrical criteria, which can be used for the grading of obstructive uropathy. In particular, morphometric data improve the accuracy of the diagnosis. Measurement of the anterio-posterior diameter of the renal pelvis and assessment of the renal volume will make postoperative monitoring more objective and therefore safer. Diuresis sonography, under standardized conditions, excludes false negative findings and clarifies borderline cases of suspected obstruction of the urinary tract. Renal sonography is a reliable method for excluding and diagnosis of urinary tract obstruction in childhood, when one is aware of its limitations.
