An intravenous pyelogram (IVP) is an imaging test used to examine the urinary tract, including the kidneys, ureters, and bladder. It involves the injection of contrast dye into a vein, which then travels through the bloodstream and collects in the urinary system, making these areas visible on x-ray images. The test can help diagnose various urinary tract disorders such as kidney stones, bladder or ureter stones, kidney cysts, enlarged prostate, tumors in the kidneys, bladder, or ureters, birth defects affecting the urinary tract, and scarring from urinary tract infections. While IVP is not as commonly used today, it may still be useful in certain situations, and healthcare providers may recommend it based on individual circumstances. In some cases, a CT scan, MRI scan, or ultrasound may also be options for examining the urinary tract.
