The renal clearances of creatinine and beta 2-microglobulin of patients with either normal or impaired kidney function were measured. The renal clearance of beta 2-microglobulin depends on the urinary pH and must be considered as an apparent renal clearance because after tubular reabsorption the compound is metabolized in the kidney. Impaired kidney function reduces the percentage of tubular reabsorption of beta 2-microglobulin.
150 gentamicin-PMMA-beads were implanted (+ 160 mg gentamicin i.v. preop.) in a woman aged 73 years and with severely impaired kidney function. Frequent determination of gentamicin plasma concentrations and renal functions were possible. The plasma concentration reached a plateau at approx. 3 micrograms/ml. No accumulation of gentamicin in plasma occurred.
