Penile Doppler ultrasound testing
Is an extremely useful investigation in erectile dysfunction (ED) and Peyronie's Disease. It is a sophisticated test to objectively measure the blood flow in and out of your penis.
Penile Doppler ultrasound is done to:
- To describe anatomy and US anatomy of the penis.
- To review the study protocol of US of the penis, in order to learn how to
- perform the exam.
- To illustrate the spectrum of lesions involving the penis, reviewing the typical
- and atypical sonographic appearances of pathologic disorders of the penis
- with correlation with other imaging techniques (MR).
- To emphasize pitfalls, diagnostic difficulties and differential diagnosis.
- Traumatic injury of the penis with impairment of its function or anatomical integrity.
- Erectile dysfunction.
- Chordee caused by a congenital abnormality of development or growth of fibrous tissue (Peyronie's disease).
- pathological lesions,
- Planned examination for plastic or reconstructive surgery on the penis.
Sonographic examination of the penis is performed with the patient in either the supine or lithotomy (frog leg) position with the penis lying on the anterior abdominal wall or supported with towels between the thighs. High-frequency (7.5–14 MHz) linear array transducers are used to obtain high-resolution images of the penis. A sufficient amount of sonographic acoustic gel should be used on the surface of the penis to obtain good-quality images, and excessive compression by the transducer should be avoided, especially in patients with trauma. The examination is performed in transverse and longitudinal planes starting at the level of the glans and moving down to the base of the penis. A transperineal approach may be used if required to assess the base of the penis.
- Inflammation of penis tissues.
- Traumatic injuries of the vessels, cavernous and spongy bodies.
- Benign or malignant tumors
- Vascular diseases of the external genitalia.
- Peyronie's disease or the chordee.
