title: [Sonography of the uretero-vesical junction and the urinary bladder in children].
abstract: Sonography of the ureterovesical junction and of the urinary bladder is described on the basis of examinations of 41 children. This included all distended bladder walls, ureteral dilations, ureteroceles and a rhabdomyosarcoma. Sonographic imaging presents difficulties in visualising ureters less than 6 mm wide, and in case of normal uretero-vesical junctions. Sonography cannot assess a versicoureteral reflux. Sonography should not be used in the first diagnosis of nephrourological changes as an alternative to radiological methods, since this may result in overlooking relevant curable changes in children. Sonography is particularly valuable in clarifying renal insufficiency and in following up children with nephrourological disease.
