### What is a Retrograde Pyelogram? A retrograde pyelogram is a diagnostic test that uses X-rays to look inside your kidneys, bladder, and ureters. Ureters are the tubes that connect your kidneys to your bladder. This test is often done during a procedure called a cystoscopy. ### How is it Done? During the test, a special dye is injected into your ureters. This dye makes certain parts of your urinary system show up more clearly on the X-ray. You will be given anesthesia to make you comfortable during the procedure. ### Why is it Done? Your doctor might order this test to check how well your urinary tract is working. They might suspect a blockage in your ureter or kidney or want to investigate the cause of blood in your urine. The test can also check the position of a stent or catheter if you have one. ### What Should You Tell Your Doctor? Before the test, inform your doctor if you are pregnant, have kidney disease, or are allergic to the dye or anesthesia. Also, let them know if you are taking any medications, especially for diabetes, as some drugs can increase the risk of complications. ### Possible Complications Some risks include bleeding, infection, nausea, vomiting, and bladder tears. If you are dehydrated, you may not be able to undergo the test. ### Preparation Your doctor will explain the procedure and may ask you to sign a consent form. You might need to fast and take a laxative before the test. ### After the Test Your doctor will review the results to see if there are any issues with your urinary tract.
