[The association of hypernephroma and dysfunction of the pyeloureteral junction. Apropos of a case]. / Asociación de hipernefroma y disfunción de la unión pieloureteral. A propósito de un caso.

We report on a patient with a tumor coexisting with a congenital condition. The foregoing conditions are discussed separately and their clinical and radiological features are described and compared with the findings commonly reported elsewhere. Finally, the conclusions relative to this uncommon case and its atypical mode of presentation are put forward.

[Echography in the diagnosis of pathology of the gallbladder and bile ducts. Personal experience]. / La ecografía en el diagnóstico de la patología de vesícula y vías biliares. Experiencia personal.

We evaluated the echographic findings in gallbladder and bile duct disease in 300 patients. These findings were correlated with those obtained after surgery and post-mortem study. The literature was reviewed to compare our results with those of other authors. In some pathologies, mainly those involving distension of the choledochus, echography must be accompanied by other diagnostic techniques, endoscopy and conventional radiology, to determine the cause of the obstruction responsible for distension. Finally, we conclude that echography is very efficient in this kind of exploration because of its high diagnostic reliability, its innocuousness and the fact that barium contrast is not required.
