IVP (Intravenous Pyelogram), also known as IVU (Intravenous Urogram), is a radiological test used to assess the urinary tract, including the kidneys, ureters, and bladder. It involves the injection of a special iodine-based contrast dye into a vein, usually in the arm. As the dye travels through the bloodstream and is filtered by the kidneys, it outlines the urinary tract on a series of timed X-ray images.
This test allows doctors to evaluate:
Kidney stones
Tumors or cysts
Ureteral obstructions
Bladder function
Congenital anomalies or structural defects
Causes of blood in urine (hematuria)
Procedure:
The patient receives a contrast injection.
X-ray images are taken at intervals to track the movement of the dye.
The test typically takes 30–60 minutes.
Preparation: Patients may be asked to fast for a few hours and may need a laxative to clear the bowels for better imaging clarity.
Safety Note: Inform your doctor if you have a history of allergy to iodine/contrast dye, kidney disease, or pregnancy, as alternative imaging like ultrasound or CT scan may be considered.
IVP/IVU is a safe, valuable diagnostic tool that helps in accurately detecting and planning treatment for urinary tract conditions.
