[The ultrastructure of the lymphatic capillaries of the human kidneys with various lesions].

Puncture biopsy of the kidneys was carried out in 15 patients with different renal lesions. General clinical, laboratory, light microscopy and electron microscopy of the biopsy specimens were employed. Electron microscopy revealed varying changes in the endotheliocytes of the lymphatic capillaries (increased functional activity, destruction of the lymphatic capillary wall). The diagnostic and prognostic value of the findings is discussed.
