What is a Retrograde Urethrogram?

Retrograde urethrogram is a tool used to evaluate trauma to the penile urethra or urethral disease.

For this test, a catheter is inserted about two centimeters into the penis. Contrast dye is injected through a tiny balloon on the catheter. Several X-rays are taken, or a fluoroscope is used to clearly see details on a special screen. If needed, the catheter is moved to fill the bladder. The patient is instructed to urinate while several more X-rays are taken.
