[Compensatory-adaptative processes of the kidney after undergoing hydronephrotic transformation].

In experiments on 30 white mongrel adult rats of both sexes pathologic and reparative alterations in the kidney by the 30th day after recanalization of the ureter occluded for 1, 3, 7, 10, 15, 30 days have been studied using microdissection, light optic and electron microscopic methods. The fact has been established that in early times of HT (1 to 3 days) with the following reduction of urinary passage through the ureter (30 days), the canalicular-vascular formations of the kidney acquire normal morphological structure. In cases of more prolonged occlusion of the ureter (15 to 30 days) in the kidney noticeable destructive alterations prevail with replacement of parenchymatous elements by connective tissue.
