The histopathological study revealed tlesiosn compatible with renal dysplasia. This lesion, which is usually congenital, is a disorganized development of the renal parenchyma due to anomalous differentiation. It can be secondary to intrauterine uretheral obstruction. In the pig it has been associated with hypovitaminosis A during gestation. The presence of edema, secondary to renal failure in this case, especially in the perirrenal location, could be suggestive of a swine fever infection.
