Abstract

Differential antibiotic excretion studies in eight patients with unilateral structural pyelonephritis showed that in all instances there was impairment in antibiotic excretion on the affected side compared with the normal kidney. Both peak and mean urinary concentrations were decreased on the structurally abnormal side. The degree of defect in antibiotic concentration was proportional to the amount of unilateral medullary damage, as measured by differential renal function studies. While the antibiotic concentrations achieved had an inconsistent relationship to cure in three patients with proven unilateral infections, the striking decreases in urinary antibiotic levels may argue against oral penicillin-G treatment of unilateral pyelonephritis in which there is renal parenchymal damage.
