[The value of quantitative functional scintigraphy of the kidneys in urology (author's transl)]. 1977

H G Heinze, and F Eisenberger, and K J Pfeifer, and J M Zimmer

The results (in 221 cases) of quantitative functional scintigraphy (Q.F.S) using 125I-hipuran (sequential scintigraphy ROI-nephrography, unilateral clearance studies) were compared with the radiological, laboratory, surgical, histological and clinical findings. Clearance measurements were superior to estimates of blood urea and/or creatinin levels. The width of parenchyma in the urogram or the secretion value did not provide sufficiently valuable evidence regarding renal function. Agreement between the above findings and those on Q.F.S. was observed in 85.7%. In the absence of agreement, Q.F.S. proved the more sensitive method and was more frequently correct. Additional information was obtained in 78.8% and treatment influenced in 18 to 65%, depending on the underlying disease. Q.F.S, had a determining role in the choice of treatment (nephrectomy, preservation of the kidney, conservative treatment) in relation to the estimate of function of the other kidney and is of considerable value to the urologist in pre-operative diagnosis.

D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D008657	Metabolic Clearance Rate	Volume of biological fluid completely cleared of drug metabolites as measured in unit time.

D011866	Radioisotope Renography	Graphic tracing over a time period of radioactivity measured externally over the kidneys following intravenous injection of a radionuclide which is taken up and excreted by the kidneys.

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
