A pyelogram is a diagnostic medical procedure that involves imaging the kidneys and the urinary tract using contrast dye. It is commonly known as an intravenous pyelogram or an excretory urogram. This procedure helps healthcare professionals evaluate the structure, function, and abnormalities of the kidneys, ureters, and bladder.
During a pyelogram, a radiopaque contrast dye is injected intravenously into the patient's bloodstream. As the dye travels through the bloodstream, it is filtered by the kidneys and excreted into the bladder, which allows the visualization of the urinary system on X-ray or fluoroscopic images. These images provide valuable information about the size, shape, and condition of the kidneys, as well as any blockages, tumors, or abnormalities in the urinary tract.
Pyelograms are typically used to diagnose conditions such as kidney stones, urinary tract obstructions, urinary tract infections, kidney tumors, and other abnormalities. They can also be used to guide treatment procedures, such as the insertion of stents, removal of kidney stones, or placement of urinary catheters.
Though generally safe, pyelograms may carry a small risk of allergic reactions to the contrast dye, and patients with pre-existing kidney disease or certain medical conditions may have an increased risk of complications. Therefore, it is important for patients to inform their healthcare provider of any allergies, medical conditions, or medications before undergoing a pyelogram.
