This study evaluates the structure and to some extent the function of the renal tract (kidneys, ureters and bladder).
Specialised x-ray equipment and technique is used called tomography.
Pregnancy must be excluded due to the radiation risk.
Intravenous contrast material is used. A history of allergies is thus important.
The IVP has largely been superseded by CAT scanning which excludes renal stones and also defines other pathology.
