1. Introduction 100%

Role of Ultrasound in Penile Evaluation
Indications: Erectile Dysfunction, Priapism, Trauma, Masses, Peyronie’s Disease
Benefits of Real-Time, Dynamic Vascular Imaging
Limitations Compared to MRI

2. Penile Anatomy 100%

Corpora Cavernosa and Corpus Spongiosum
Tunica Albuginea and Buck’s Fascia
Urethra and Glans Penis
Dorsal and Cavernosal Arteries
Veins and Neurovascular Bundle

3. Scanning Techniques 100%

High-Frequency Linear Probe (10–15 MHz)
Transverse and Longitudinal Views
Baseline (Flaccid) and Post-Vasoactive Injection Evaluation
Patient Preparation and Privacy Considerations
Use of Color and Spectral Doppler

4. Normal Penile Ultrasound Appearance 80%

Symmetrical Corpora Cavernosa
Homogeneous Echotexture
Visible Tunica Albuginea and Urethra
Arterial Waveform: Low Resistance in Erection Phase
PSV > 30 cm/s Considered Normal

5. Vascular Evaluation and Erectile Dysfunction

1. Arteriogenic ED

Low Peak Systolic Velocity (PSV < 25 cm/s)
Absent or Poor Rise After Injection

2. Venogenic ED

Normal or High PSV with Persistent Diastolic Flow
Lack of Adequate Rigidity

3. Priapism

Low-Flow: Minimal/Absent Flow, Painful
High-Flow: Cavernosal Fistula, Color Flow Turbulence
Post-Traumatic Evaluation

6. Structural Abnormalities

1. Peyronie’s Disease

Fibrous Plaques in Tunica Albuginea
Calcifications and Shadowing
Associated Penile Curvature

2. Penile Fracture

Disruption of Tunica Albuginea
Hematoma Formation
Urethral Injury Evaluation

3. Urethral Pathologies

Urethral Stricture
Urethral Diverticulum
Fistula Assessment (If Suspected)

7. Penile Masses and Tumors 30%

Squamous Cell Carcinoma
Subcutaneous Cysts or Lipomas
Hemangioma
Inflammatory Lesions (Abscess, Fournier’s)
MRI for Further Evaluation if Indeterminate

8. Interventional and Post-Operative Assessment 0%

Post-Injection Vascular Response Evaluation
