[Simultaneous determination of effective renal plasma flow and glomerular filtration rate using a double isotope technic--determination of the filtration fraction].

A method for the simultaneous determination of the effective renal plasma flow and of the glomerular filtration rate with the help of 131J-o-iodohippuric acid and 169Yb-DTPA using a double isotopic technique is described. Apart from this the method serves for the establishment of the filtration fraction. 40 patients with different clinical pictures (glomerulonephritis, pyelonephritis, cystic kidneys, stenosis of the renal artery) were examined. The clearance values established by us were in the areas characteristic for the clinical pictures. Pathological conditions could be established which are not yet characterized by an increase of the fixa of the urine in the serum. By the determination of the filtration fraction differential-diagnostically important insights are afforded. The examination is methodically simply to be performed and is of little stress for the patient. Therefore it seems to be suitable for the routine examination.

[Determination of the renal clearance in combination with isotope nephrography].

The possibilities of a determination of the renal clearance including the separation of sides with the help of simple nuclear-medical examination and measuring techniques are described. In 50 patients the determination of the effective flow of renal plasma was carried out with 131J-labelled iodohippuric acid. Methodic variants were compared. The examinations of the patient last one hour. They can be carried out in the outpatient department within the isotopic nephrography. In addition to this only several takings of blood samples are necessary. A catheterization of the urinary bladder as it is necessary for the classical determinations of the clearance is no more to be done. The results show that with the help of the methods described valuable quantitative informations about the function of the kidneys are to be got.
