INTERSTITIAL HANDLING OF AMINOGLYCOSIDE ANTIBIOTICS AND RADIOGRAPHIC CONTRAST MEDIA IN THE KIDNEY
Abstract
Lymphatics of the mammalian kidney originate in
the loose connective tissue around large blood vessels.
This paravasal tissue drains the interstitium. The in-
trarenal lymphatic system consists of interlobular
arcuate, and interlobar vessels according to the
architecture of the arterial system. The interlobar
vessels drain into the hilar lymph vessels. Capsular
lymphatics are connected with the interlobular
lymphatics inconsistantly. The renal medulla is drained
by the venous vasa recta exclusively - there are no
lymphaties in the medulla.
Lymphatic fluid is mainly formed along the small
renal veins as vascular transudate.
After i.v. bolus injection concentrations of amino-
glycosidic antibiotics in renal lymph reflect plasma
values closely. Radiographic contrast media in renal
lymph also showed a close correlation with plasma
values with some indication of tubular secretion.
