By using renal scintigraphy the function and excretion of the kidneys can be separately examined. Essentially there are three different partial functions:
- perfusion of both kidneys for each side separately
- tubular secretion of both kidneys for each side separately
- urine flow from the pelvicocaliceal system and through the ureter
These examinations are in particular important in order to detect the function of the kidneys, e.g. in cirrhotic kidneys, recurring kidney inflammation and mechanical transport disturbances of the urine (outflow obstructions). In functionally relevant outflow delays surgical treatment is usually necessary.
