Pyelogram for bladder cancer
Another type of pyelogram test is known as retrograde pyelogram. This imaging test for bladder cancer also uses a dye to improve the view of the bladder area. With this approach, the dye is injected through a catheter that is placed through the urethra and into the bladder or ureter. This test is useful for people who are allergic to the dye used for the X-ray test.
What is a pyelogram?
This imaging test can help with monitoring the cancerous tissue, and determining if the cancer has spread beyond the bladder. A pyelogram is pefrormed before an X-ray, to help identify specific areas.
For an intravenous pyelogram (IVP) - also known as a intravenous urogram (IVU), a special dye is injected into a vein and then flows into the ureters and bladder. When an X-ray is then taken, the dye outlines the bladder area, which helps in identifying urinary tract tumors.
