we conclude that in csa-induced chronic nephropathy 99mdtpa and inulin are unrestricted by the glomerular capillary wall and behave as true filtration markers , creatinine is progressively hypersecreted by renal tubules as the nephropathy worsens , and the ensuing enhancement of creatinine clearance over gfr blunts the expected rise in serum creatinine levels as gfr falls .
