US penis/prostate

sonographic findings of adenocarcinoma

• Hypoechoic lesion in peripheral zone

• May disrupt symmetry of gland contour

• May appear heterogenous

prostitis sonographic findings

• Hypoechoic gland

• May see hypo or anechoic mass within prostate

BPH sonographic appearance

• large round gland

• Central portion protrudes anteriorly

• Sometimes it appears to compress peripheral zone

The prostate gland should be

symmetrical in shape and echogenicity

prostate urethra sonographic appearance

Echogenic line through midline of the prostate gland

seminole vesicle sonographic appearance

Anechoic or very hypoechoic

transitional zone sonographic appearance

Hypoechoic, same as peripheral

Central zone sonographic appearance

Usually hyperechoic to peripheral zone

peripheral zone sonographic appearance

Hypoechoic

prostate transrectal ultrasound procedure

• Scan prostate from left to right in sagittal

• Scan Seminal vesicles and prostate gland from superior to inferior in axial

prostate transrectal ultrasound patient position

Left lateral decubitus

prostate ultrasound patient prep

• Clear liquids before

• Tapwater or enema may be ordered

how does sonographer scan prostate?

• Transrectum To assess size or masses

reasons for a prostate ultrasound

• Enlarged prostate

• Decreased urine output or dysuria

• Urinary urgency

• Increased PSA

• Cancer history

• Irregular ct or mri

Fibromuscular stroma ultrasound

• Hypoechoic area near bladder

• Small and hard to see

ultrasound elastography is useful for

monitoring disease progression and treatment responses

erect exams are good for

• Enhances plaque

• Shows hypoechoic or isoechoic lesions

• Stretches Tunica albuginea for better assessment

flaccid exams are good for

• assessing major plaque

• Dorsal nodules

• Calcification

erectile dysfunction:

Doppler ultrasound evaluates penile blood flow after

Induced direction

erectile dysfunction Assessment is ______ Ultrasound on penile

Most common

penile ultrasound allows, real-time examination of

• corpora cavernosa

• corpus spongiosum

• vascular structures

ultrasound peyronie’s disease detection

fibrosis plaques causing penile curvature

trauma and mass evaluation ultrasound sees

• Penile trauma

• Palpable mass

• Urethral structures

• Foreign bodies

penis ultrasound probe

linear array 7 to 18 MHz

things to document

• Measurement of plaque

• Hematoma

• Masses

ultrasound position for penile patient

Supine lithotomy

ultrasound appearance of Peyronie’s disease

hyperechoic plaque appears within Tunica albuginea causing penile curvature

ultrasound of erectile dysfunction

Doppler imaging measures peak systolic and end diastolic velocities in cavernosal arteries

ultrasound penile fracture

Disruption of Tunica albuginea With association to hematoma visible on ultrasound

priapism vascular changes

Altered vascular dynamics, differentiate, low and high flow priapism on Doppler imaging

Red on the color map indicates

soft, high strain

High resolution, grayscale images identify

• Tunica albuginea thickening (>2 mm)

• Calcifications

• Septal fibrosis

• intracavernosal fibrosis

what state is the penile exam done in?

Flaccid or medically induced erection

ultrasound elastography

measures tissues rigidity, providing quantitive data on plaque stiffness

Blue on the color map indicates

Stiff, low strain

penile fracture on ultrasound

• Disruption of tunica albuginea

• Hematoma

• Possible involvement of urethra
