[Renal hypoplasia and familial vesicoureteral reflux. A rare association]. / Hipoplasia renal y reflujo vesicoureteral familiar. Una rara asociación.

Presentation of two cases of unilateral congenital renal hypoplasia with vesicourethral reflux in two male siblings, no twins, both diagnosed at the age of 24. With no urological history, they present with a dysuria-pollakiuria syndrome which does not even allow to have a clinical suspicion of the final diagnosis. Clinical features of both cases are discussed, and the hyperplasia-reflux association, as well as the possibility of the condition having a hereditary and familial nature, are confirmed by clinical observation as well as radiological and histological data. A literature review is undertaken but published references are very scarce.

[Hypernephroma in childhood (author's transl)]. / Hipernefroma infantil.

A case of hypernephroma in a 9 years old male is presented. The palpable mass in the right hypochondrium orientated towards a solid renal mass confirmed by intravenous pyelography, ecography and angiography. The final diagnosis was clarified by the histopathological study, due to the low incidence of hypernephroma in children. Authors believe this is the second case published in this country.
