It can detect kidney stones, urinary tract obstructions, tumors, congenital abnormalities, and cysts in the kidneys or bladder.

A contrast dye is injected into a vein, and X-ray images are taken as the dye travels through the kidneys, ureters, and bladder, helping to visualize any abnormalities.

The primary risks include exposure to radiation and potential allergic reactions to the contrast dye, although these are uncommon.

A radiologist will review the images and send the results to your doctor, who will typically discuss the findings within a day or two, depending on the urgency of the condition.
