Penile Pathology

vascular impotence is caused by

vascular compromise to or within the penis that results in the inability to obtain or maintain an erection

vascular impotence could be caused by

diabetic neuropathy

diabetic neuropathy is when the

tiny vessels within the penis are damaged

in normal men, there is an increase in arterial flow to the — that can be determined by evaluating the systolic velocities

cavernosal arteries

normally, the venous outflow will become — and the diastolic flow will greatly decrease

partially blocked

teh diagnosis of venous incompetence can be made of the — does not decrease

diastolic flow

in healthy individuals, the cavernosal artery velocities measure — in the flaccid state

10-15 cm per second

— is the buildup of fibrous plaque (scar tissue) and calcifications within the penis that results in a painful curvature

peyronie disease

clinical findings of peyronie disease

1. impotence

2. painful erections

3. area of scar tissue can typically be palpated

4. marked curvature of the penis

sonographic findings of peyronie disease

1. thickening of the tunica albuginea that may also contain areas of calcifications

anatomy of the penis

fracture of the penis can occur with

blunt sexual trauma

the audible sound of a popping or cracking sound is often heard with penile trauma because typically one of the — snaps under the pressure

corpus cavernosa

Careful assessment of the tunica albugenia for evidence of penile urethra is warranted because interruption to the urethra can lead to

voiding complications

The damage from penile trauma, if not managed appropriately, can permanently disrupt

penile function

Transverse image of the penis. In this image, the transducer has been placed on the dorsal aspect of the penis in order to perform Doppler evaluation, which allows for the assessment of the two corpus cavernosa (asterisk), with the corpus spongiosum noted ventrally (hash).

clinical findings of penile trauma

1. history of hearing an audible popping sound during intercourse

2. subcutaneous bleeding area

sonographic findings of penile trauma

1. an irregular hypoechoic or hyperechoic defect at the site of rupture
