Q

what is the ductus epididymis?

A

single duct in body and tail

17
Q

What is a vasectomy?

A

surgically interrupted vas deferens

18
Q

What does the bulbourethral gland (cowper) do?

A

secretes fluid

19
Q

What is an appendix testis?

A

remnant of the Müllerian duct

ovoid structure beneath the head of the epididymis

20
Q

What is the tunica albuginea?

A

dense, fibrous tissue, completely covers testes

21
Q

What is the mediastinum testis?

A

linear stripe of variable thickness running through the testis in a longitudinal direction (craniocaudal)

22
Q

What is the tunica vaginalis?

A

serous covering of testis which is a double layer extension of peritoneum

parietal (outer) and visceral (inner) - between here is where hydrocele’s form (of the vaginalis)

23
Q

Where do hydrocele’s form?

A

between the parietal and visceral layer of the tunica vaginalis

24
Q

What is the vas deferens?

A

thin muscular tubes that carry sperm from each testicle to the urethra

25
Q

what is the verumontanum?

A

junction of the ejaculatory duct with the urethra

26
Q

What is in the spermatic cord?

A

vas deferens

testicular arteries

venous pampiniform plexus

lymphatics

autonomic nerves

27
Q

Where do the rt and lt testicular arteries come from?

A

arise from anterior Ao just inferior to Renal Artery

laterally

low resistance flow

28
Q

What are the testicular arteries?

A

capsular

centripetal

recurrent

rami (centrifual)

extratesticular:

cremateric

deferentail

29
Q

What is the pampiniform plexus?

A

the network of veins

30
Q

The right testicular vein drains into _______

A

IVC

31
Q

The left testicular vein drains into _______

A

Left renal vein

32
Q

What are the indications for a scrotal sonogram?

A

palpable mass

scrotal pain

swollen scrotum

trauma

infertility

location: have patient show you, how long? (for palpable lump)

33
Q

What is the risk if the a mass is found INSIDE the testicle?

A

malignancy

34
Q

What are you looking for when scan the testicles

A

are they similiar? compare

is there flow? absent or hyperemic

evaluate epididymis - compare flow

representative images in two planes

35
Q

When might you need to use a curved transducer?

A

if there are large hydroceles, hematomas, swelling or abscess

needed for a larger field of view

36
Q

Where do the testes reside?

A

in the scrotum

36
Q

What are the testes?

A

symmetric

oval glands

exocrine and endocrine gland

37
Q

Which artery can you sometimes see coursing through the testes?

A

transmediastinal artery

see slide 32 for picture

38
Q

How does venous drainage occur?

A

through veins of pampiniform plexus

exits mediastinum

courses through spermatic cord

converges into 3 veins

39
Q

What is one picture you must always get?

A

both testes at the same time!
