Important Information,
Preparation:
Intravenous Pyelography Instruction Leaflet
IVP Patient Information and Consent Form
Contrast Material: Required

Main Applications:

  • Kidney stones
  • Width of the renal pelvis
  • Width, length and course of the ureter
  • Bladder wall
  • Measurement of bladder volume (before and after urination)
  • Inflammatory and malignant diseases of the kidneys, the ureter and the bladder

The Examination:

With very few exceptions, the examination is performed with the patient lying down. First, a so-called plain x-ray (without contrast material) of the urinary tract (overview of the entire abdominal cavity) is taken. This permits the examining technologist or physician to identify calcifications in the body or calcified stones even before administering contrast material. This is important because small stones may be concealed by the contrast material and escape detection. Contrast material is administered as the next step to visualize the ureter and urinary bladder. The contrast material is excreted easily after a short period of time through the kidneys.

The examination usually takes about 30 minutes. During this period, X-ray images are obtained at specific intervals. In certain diseases, urine flows more slowly from the kidneys. The examination may then take several hours in these rare cases. Urine may also flow less rapidly from the bladder in case of prostate gland disease or cases of bladder descent. If such a condition is suspected, a final image is taken after the patient has emptied his/her bladder. This allows the radiologist to determine whether some urine has remained in the bladder and the quantity of such residual urine.
