This page is for information purposes only.  For advice and specific questions please contact your primary care or referring physician.

An Intravenous Pyelogram (IVP) uses X-rays and a contrast material to produce an image of your urinary tract, which includes your kidneys, ureters and bladder.  This examination is performed when patients experience kidney pain, blood in the urine, kidney stones, tumor or injury.

For the best examination of your urinary tract, your colon must be clean.  You will need to obtain a Fleet Prep Kit #2 available over the counter at any pharmacy.  Follow the instructions inside the kit.

  • You will need to drink eight ounces of water or clear liquid the morning of your examination for hydration.  Do not eat anything after midnight the night before your study. 
  • Are you diabetic?  If you are taking Metformin (Glucophage/ Glucovance), it should be stopped the morning of the exam and not resumed until you have consulted with your family physician.  (It is recommended that normal renal function, i.e. normal CR to be documented 48 hours after injection of IV contrast before resuming Glucophage/Glucovance).
  • If you are diabetic, please check with your physician to see if your medication needs to be adjusted while you are fasting.  You may be asked to do a blood test prior to procedure.   
  • It is a good idea to discuss how and when the doctor's office will contact you after the lab test is done.  We do not want you to be off your medication any longer than necessary. 
  • Because contrast material is used for the IVP, please advise the technologist if you have an allergy to medication, foods, contrast and have any history of hay fever or asthma. 

View the full prep sheet.

For Pediatric patients, children over 140 pounds need to follow the adult preparation.  Infants and young children should not eat three to four hours prior to the examination and newborns should fast two to three hours prior to the study.  Any specific concerns or questions should be answered by patient's physician.


  • You will be asked to change into a hospital gown. 
  • You will be asked to lie on the table and a technologist will take a scout film to see if your bowel is clean enough for the test. 
  • The technologist will inject contrast material through an IV line in your arm.  The IV will remain in place for the length of the procedure.  After the injection, a series of X-rays will be taken while you are lying on the table. 
  • When the kidneys, ureters and bladder have all been visualized, you will be asked to empty your bladder, after which an additional film of your bladder will be taken. 
  • The contrast is expelled as you urinate and is colorless.  You should increase your fluid intake for a day or two following your examination.

Your films will be read by a radiologist who will send a report to your physician.

Important note:
If you are of child bearing age and think there is any possibility of pregnancy it is important that you inform the physician ordering these x-rays and tell the technologist taking your x-rays.  If you have any known allergies to contrast, iodine, or foods please inform your physician BEFORE proceeding with any of the instructions that follow.
