title: [Concentration of antibiotics in long term embolized kidneys (author's transl)].
abstract: In 7 dogs renal arterial embolization was performed using Seldinger technique and inflatable Swan Ganz balloon catheter by injection of methyl methacrylate/butyl 2 cyano acrylat. Six months later tissue concentration of cefazolin was measured in the embolized and kontralateral kidneys and in serum two hours after a short infusion of 1 g of Cefazolin. The concentrations in serum and homogenized kidney tissue were determined by means of the agar well diffusion method. Angiography studies showed no vessels in the embolized kidneys. Histologically there was total atrophy of the tissue especially the tubular system. The mean tissue level of Cefazolin in the embolized kidney was 70% of serum. The tissue concentration was always above 10 microgram/g. This concentration is high enough to inhibit nearly all strains of E. coli, Klebsiella, Salmonella, Shigella and a large part of Proteus mirabilis, whereas nearly all gram-positive bacteria are inhibit at a lower concentration. Value and necessity of antibiotic therapy in embolized kidney cancer is discussed.
