TEACHING POINTS

Penile duplex ultrasonography is a relatively safe, minimally invasive method for evaluation of a number of conditions, including but not limited to Peyronie's disease as well as erectile dysfunction (ED) secondary to atherosclerotic or post-traumatic changes. Our goals are to highlight our experience with this modality by sharing our institution's protocol and to demonstrate a few select cases which highlight both normal sonographic findings as well as unique pathology.

TABLE OF CONTENTS/OUTLINE

1) Introduction to penile duplex ultrasonography2) Protocol3) Normal sonographic findings4) Sonographic findings associated with Peyronie's disease5) Sonographic findings associated with erectile dysfunction secondary to atherosclerosis6) Unique sonographic findings in a patient with erectile dysfunction secondary to prior pelvic trauma

TEACHING POINTS

Even though there are great advances in urologyc imaging, the cystogram continues to be the imaging method of choice for some pathologies, and its the radiologist duty to make a correct diagnostic impression through this method.Cystogram is highly efective, has easy access, low cost and is minimally invasiveThe correct interpretation of the cystogram by the radiologist decrease false positive results and increase our diagnostic ability.
