CT Urography with contrast

It is an imaging method that helps evaluate the urinary system, including the ureters, the kidneys, bladder and urethra (urinary tract). By injecting a contrast dye into the vein, multiple thin-slice images of the urinary system are taken. These images are then viewed by your doctor to see if the internal structures are working correctly and check for any signs of disease. The scan helps diagnose conditions such as kidney stones, bladder stones, bladder infections, kidney infections, cysts, abnormal masses, such as tumors, and structural irregularities.
