Case Discussion

The split bolus technique is a CT imaging investigation used in patients with hematuria aiming to put together, in a single image acquisition, both the nephrographic and renal excretory phases and thus reducing the radiation dose of the study. It is a CT protocol adopted for some institutions for assessing a patient with hematuria.

This is a normal example of the whole renal tract illustrated.  Often the ureters will not both be filled in their entirety with contrast.
