Renal Diuretic

What is the purpose of this scan?
The purpose of this scan is to evaluate the function of the kidneys.

How is this scan performed?
An IV is started, usually in the vein of an arm. A nurse will also insert a catheter. After the catheter and the IV are started, a small amount of radioactive material and a diuretic called lasix is administered through the IV. The lasix will make the kidneys function. The radioactivity will allow us to take pictures of the kidneys.

You will lie on a table. A camera that can detect radioactivity will take images from under the table. It is very important to hold still for these pictures.

The input through the IV and output through the catheter will also be monitored. You should plan for your procedure to take about one hour and 30 minutes.

How do I prepare for this scan?
There are no special preparations necessary for a renal diuretic scan. However, sometimes drinking fluids before the scan is helpful.

How will I feel after I have a renal diuretic scan?
The radioactive shot will have no effect on how you feel.

How soon will my doctor get the results?
After the procedure is complete, a nuclear medicine physician will study the pictures along with your medical history to make an assessment of what the images show. He will then dictate a report that will be forwarded to your physician within five to seven business days. If your doctor needs the results sooner, he/she may contact the nuclear medicine physician on the day of the exam.

How do I make an appointment?
Your doctor will write an order or prescription for the test. The doctor will either give you the order or have it faxed to the hospital. You may then schedule your appointment by calling the Nuclear Medicine Department at 847-723-5050.

If I still have questions, who should I call?
