Nuclear Medicine Diuretic Renography

Based on a clinical evaluation, your doctor may recommend nuclear medicine diuretic renography to further evaluate the function of your urinary tract. We hope this introductory brochure will help you understand this study better.

The purpose of the nuclear medicine diuretic renography is to diagnose and monitor urinary tract obstruction.

Procedure for the study

  • No fasting is required beforehand; you need to drink at least 500 milliliters of water 30 minutes before the study.
  • At the time of the study, go directly to the scanning room. We will inject a tracer into your vein, and immediately image your flank region for 30 minutes nonstop. Our medical staff will inject a diuretic in your vein 15 minutes after the tracer injection.

Things to keep in mind

  • Notify our medical staff if you are pregnant or if you are allergic to diuretics. If you had any radiological injected contrast medium or any radiological procedure for imaging blood vessels of the kidney in the last 3 days, inform us as well because it is inappropriate for your condition to have nuclear medicine diuretic renography.
  • Empty your bladder before imaging. Do your best to remain still during imaging. This will improve the quality of the image. There are no other special precautions and complications like allergy are rare.
