[Estimation of individual renal function by Tc-DMSA-uptake (author's transl)].
Hg-Cl2-accumulation and early hippuran uptake are widely used for the estimation of individual renal function, a clinically important procedure in nephrological-urological nuclear medicine. After clinical experience in more than 2500 patients we investigated the assessment of individual renal function by the uptake of Tc-DMSA, a new radiopharmaceutical for renal scintigraphy. Tc-DMSA-uptake was measured after application of 0.8-1.6 mCi Tc-99m-DMSA by a scintillation camera connected to a computer system and by a rectilinear scanner with data storage, additionally hippuran kinetics were registered with a scintillation camera, the total body clearance was performed due to the method of Oberhausen with a modified whole body counter. A good agreement and high correlation between Tc-DMSA-uptake with background corection and the unilateral renal clearance could be established. This easily available and clinically valuable method also can be adjusted to institutions with a rather simple equipment.
