Renal Scan with Lasix

Preparation:
There is no special preparation for this exam.  You may eat, drink and take any medications that you need to prior to this exam.  It is highly recommended that you be well hydrated prior to this procedure.  There is no need to hold your bladder.  You will be instructed to drink a lot of fluid and empty your bladder often prior to this procedure.

What to Expect:
Upon arrival to our reception area, you will be escorted back to the Nuclear Medicine suite by one of our team members.  In the Nuclear Medicine suite, a Technologist will explain the procedure to you, discuss your symptoms (if any) and medical history and start an IV in vein in your arm (or hand). 

The Technologist will assist you onto the imaging table and position the camera so that it is just below your kidneys.  He/she will then inject a small amount of radiopharmaceutical (MAG3) through your IV.  The scan will begin immediately and you will be asked to hold very still.   The scan itself takes 60 minutes.  For maximum comfort, you will be lying on your back with a pillow under your head and knees covered with a warm blanket.  Feel free to bring along your favorite DVD movie or music CD to use during your procedure or you may choose from our selection.

After the first 20 minutes of imaging is completed, one of our Radiology Nurses will inject a medication called "Lasix" into your IV.  Lasix is a diuretic and will assist your kidneys for the procedure.

The scan will continue for an additional 40 minutes.  Once the imaging is complete, the Technologist will evaluate the image for quality, remove the IV from your arm (or hand), address any issues or concerns that you may have and escort you back to the reception area.

Common reasons to perform a Renal Scan with Lasix include (but are not limited to):

  • Evaluation of renal ureteropelvis or ureterovesical obstruction
