17
Q

Ochitis and testicular tumors can cause the prostate to?

A

Increase in size

18
Q

Most common prostatic disorder?

A

Benign prostatic hypertrophy (BPH)

This is increase in INTERcellular volume rather than an increase in the number of cells

19
Q

Chronic BPH causes what in the prostate?

A

Cysts! from dilations of ducts and spaces

20
Q

Cysts can predispose the prostate to what?

A

Infection…just like cystic endometreosis

21
Q

Second most common condition of the prostate?

A

Prostitis - mostly bacterial

  1. Hard for antibiotics to reach
  2. Can be a nexis of infection for other systems if not cleared
22
Q

Types of prostitis?

A

Fluminant hemorrhage and emphysematous causing rupture

to

Mild

23
Q

What can a ruptured prostate cause

A

Peritonitis (abscessed prostate or just prostitis)

24
Q

Uterus masculinus is?

A

Cystic expansion of the muellerin ducts causing uterine like structures just dorsal to the bladder.

25
Q

Is prostatic adenocarinoma common?

Where does it like to spread?

A

No

Regional LN, lungs, liver

26
Q

Clinical signs of prostatic disease?

A

Ribbon like feces

Stranuria, hematuria, pyuria

Abdnormal gait

Painful on abdominal palpation

27
Q

What is the vesicoprostatic sign/junction?

A
28
Q

Prostate that exceeds 90% of the sarcal pubic distance is suggestive of?

A

Neoplasia, abscess, cyst

aka mass lesion

However, size is hugely variable! anything can be anything. BPH up to 10x the normal size

29
Q

Inflammation around the prostate can cause?

A

Focal loss of detail.. look for that also

30
Q

Mineralization of the prostate is indicative of?

A

Long standing prostatis

Neoplasia

31
Q

Whispy or streaked mineralization in an early neutered dog is concerning for?

A

NEOPLASIA

32
Q

Intrapelvic, prostatic and urinary tumors like to mets to?

A

Lumbar and sarcal vertebra (ventral body)

33
Q

Poor prognostic indicators for prostate disease include

A

Gas in prostate

Invasion or compression of urethra

34
Q

Should contrast in the prostate from urethrogram be concerning?

A

Only if it pools… small amounts in the ducts is fine

Filling defect of the dorsal urethra at the level of the prostate is normal

35
Q

The prostate is easier to image from what side of the os penis on US?

A

The right

36
Q

Symmetrical enlargement likely?

A

BPH

Though chronicity and cyst development can fuck up symmetrical enlargement

FALSE… very rare
