Determination of total, divided and regional tubular clearance and excretion by compartmental analysis of camera renograms. 1978

I H Wolf, and G Buttermann, and H W Pabst

A method to analyze the camera renogram is described in a mathematical manner. It is based on a 6-compartment model, which simulates the hippurate in vivo kinetics. Results are transfer rate constants from which the tubular clearance (by multiplying with the plasma volume) and additionally excretory parameters can be derived. The method is quick and simple and needs a gamma-camera and a small data processing system only, but no special equipment and no blood sampling.

UI	MeSH Term	Description	Entries
D007457	Iodine Radioisotopes	Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes.	Radioisotopes, Iodine
D007677	Kidney Function Tests	Laboratory tests used to evaluate how well the kidneys are working through examination of blood and urine.	Function Test, Kidney,Function Tests, Kidney,Kidney Function Test,Test, Kidney Function,Tests, Kidney Function
D007684	Kidney Tubules	Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER.
