In 111 Patients with a wide range of renal function (normal to advanced renal failure) the renal clearances of Na-paraaminohippurate (CPAH) and of Na-orthojodohippurate--J125(COJ(J125(H) have been simultaneously determined under standardized clearance conditions. We found a significant correlation between the 2 parameters, defined by the equation CPAH =(More)
In 111 Patients with a wide range of renal function (normal to advanced renal failure) the renal clearances of Na-paraaminohippurate (C PAH) and of Na-orthojodohippurate-J125 $$\left( {C_{OJ(J^{125} (H} } \right)$$ have been simultaneously determined under standardized clearance conditions. We found a significant correlation between the 2 parameters,(More)
