[Morphological lesions of the kidney in acute bilateral subrenal occlusion].

Abstract

The effect on the kidney of a bilateral transitory occlusion of the ureter was studied. The extent of the oedematous swelling of the kidney was determined and the dilation of the pelvis and the condition of the vessels were studied. Changes were observed in the renal tissue. The vessels appeared to be in a functional spasm, Bowman's capsules and the tubules were dilated and signs of vacuolar degeneration were manifest in the parenchyma. Mannitol administered after relieving the occlusion enhanced renal regeneration. The oedema disappeared in a shorter time than otherwise and the degenerative symptoms ceased.
