[Transformation of the kidney lymphatic system in clinical pathology].

The nature of transformations in the renal lymphatic system in the clinical pathology of the kidneys, mainly in the final stage of chronic glomerulonephritis, hypertension, atherosclerosis, hydronephrotic transformation (45 autopsy kidneys) is demonstrated. The controls consisted of kidneys from patients dying with non-renal pathology (12 organs). In the final stages of the above diseases progressive reduction of the intraorgan lymphatic capillaries and vessels with simultaneous marked vascularization of the fibrous renal capsule due to an increase in the amount of lymphatic capillaries (their growth) and formation of new abducting lymph stems, numerous anastomoses between them, as well as distention in the vessel lumens and the development of varicosis of the wall. These morphological changes indicate high plastic properties of the lymphatic system and its role in the retention of the renal function in developing "Локально" lymph congestions in the organ because of outgrowth of the connective tissue. On the other hand, they are universal and reflect the time course of the progress.
