title: Radionuclide evaluation of renal function.
abstract: The renal scintillation camera study and the excretory urogram should be considered to be complementary studies. The renal scintillation camera study provides an accurate evaluation of changes in total, differential, and segmental renal function but affords only a gross assessment of anatomic changes. The excretory urogram provides superior information about renal anatomic changes but only inferior information about functional changes of the kidney. The advantages of a renal scintillation camera study with regard to the patient are that it is done in a state of normal hydration, it requires no bowel preparation, it is not associated with allergic reactions, it provides a low radiation exposure, and it is a noninvasive procedure for differential renal function which requires no ureteral catheters.
