Dynamic Infusion Cavernosometry Cavernosography (DICC)

This information explains your dynamic infusion cavernosometry and cavernosography (DICC) procedure.
 
DICC is used to:
  • Assess the cause of erectile dysfunction (ED)
  • Learn more about a curvature in your penis related to Peyronie’s disease. This will help your doctor decide if surgery is an option to correct it.
Most men need only the cavernosometry. 
 

What is the purpose of this procedure?

A DICC measures the blood pressure in your penile arteries and in your penis. It helps tell us what is causing  your ED. For example, you may have low blood flow to your penis, or you may have a leaky valve. If you have Peyronie’s disease, the test can help us decide if surgery is an option to correct the curvature in your penis.
 

How safe is this procedure?

This procedure has been used for over 20 years and is considered safe. Please see “After Your Procedure” for more  information.
 

Before Your Procedure

Ask about medications

Tell your doctor or nurse if you have recently taken a monoamine oxidase (MAO) inhibitor. These are used to treat depression. Examples are:
  • Phenelzine (Nardil®)
  • Deprenyl (Emsam®)
  • Tranylcypromine (Parnate®)
If you are not sure if the medication you take for depression is an MAO inhibitor, ask your doctor or nurse.
 

Do not take the following medications before your procedure: 

  • Sildenafil citrate (Viagra®) or vardenafil (Levitra®) for 24 hours before and 24 hours after your procedure
  • Tadalafil (Cialis®) for 72 hours before and 24 hours after your procedure 
  • Over-the-counter decongestants with pseudoephedrine (Sudafed®) for 24 hours before your procedure 

During Your Procedure

Your procedure will take about 30 minutes. You will put on a hospital gown and lie on your back on an exam table. 
 
Your penis will be numbed with a tiny injection of local anesthesia. Two small needles will be inserted into the shaft, which is the portion of your penis that is halfway between the head and body of your penis. You will get medication through 1 needle to cause an erection. The other needle lets us measure the blood pressure and blood flow in your penis. You will not feel any pain during the procedure. 
 
Your doctor will discuss the results with you after the test. You will then be able to discuss treatment options.
 

After Your Procedure

In the recovery room

You will have:
  • Bruising on the shaft of your penis
  • Mild discomfort around the needle sites once the local anesthesia wears off
A possible side effect of the procedure is a prolonged erection. This can be dangerous because it can damage the tissue in your penis that helps you have an erection. To be safe, you will stay in the department for up to 1 hour after the procedure. Some men need to take medication to reverse the erection if it does not go away on its own. Your doctor or nurse will check your penis to see if it is still erect before you are discharged. 
 

At home

You can take acetaminophen (Tylenol®) or ibuprofen (Advil®) for pain relief. 
 
You can resume sexual activity the day after your procedure. Do not take oral (by mouth) medications or penile injections for ED for at least 24 hours after your procedure.
 

Call your doctor or nurse if you have:

  • A rigid erection on your way home that:
    • Stays hard enough for intercourse 
    • Lasts for 1 hour or more
  • A temperature of 101° F (38.3° C) or higher
  • Pain that is not relieved with acetaminophen or ibuprofen
