Term
  • Central zone
  • Peripheral zone
  • Transition Zone
  • Periurethra glandular  tissue or zone
Definition
In sectional imaging, the prostate is divided into four zones:
Term
Peripheral zone
Definition
largest prostate zone and most common zone for prostate cancer
Term
central zone
Definition
  • Bordrs the seminal vesicles
  • Ducts of the vas deferens and sminal vesicles enter this zone and the ejaculatory ducts pass through the zone
  • Resistant to disease processes and is site of only 5% of cancers
Term
Transition Zone
Definition
  • Small area located on the lateral sides of the proximal prostatic urethra
  • This zone borders the central zone posteriorly and laterally; the fibromuscular tissue is anterior
  • most common zone for benign prostatic hypertrophy
Term
Periurethral glandular zone
Definition
Contains the tissue that lines the proximal prostatic urethra
Term
prostate gland
Definition
a fibromuscular and glandular organ shaped like an inverted pyramid and is posterior to the bladder
Term
prostate gland
Definition
largest accessory gland of the male reproductive system
Term
urethra
Definition
Passes through the center of the prostate before traveling to the penis to the end at the external urinary orifice
Term
prostate
Definition

secretes a thin, milk-colored fluid that constitutes about 30% of the total seminal fluid volume

 

Helps to activate sperm and maintain mobility

Term

transverse 4cm

Anteroposterior 3cm

Definition

Definition
Prostate experiences how many growth spurts?
Term
16.7%

American men have a _____ risk of being diagnosed with prostate cancer
Term

Homogeneous appearance

Anterior fibromuscular stroma is hypoechoic

Uretha may appear echogenic

Definition
Sonographic appearance of prostate
Term

Bening Prostatic Hypertrophy

BPH

Definition
When prostate enlarges as a man ages
Term
  • Hesitant or weak stream
  • Leaking/dribbling
  • Increased urinary frequency, particularly at night (nocturia)
Definition
Symptoms of BPH
Term

Definition
Prostate cancers generally appear how sonographically in relation to adjacent tissues?
Term
Adenocarcinoma
Definition
Most common maliganant neoplasm of the prostate
Term
  • Frequency of urination
  • Urgency
  • Hesitancy with weak stream
  • occasional hematuria
  • elevation of acid phasphatase is highly suggestive of cancer
Definition
Symptoms of prostate cancer
Term
benign process
Definition
Calcifications are indicative of a what?
Term
Focal alteration of echogenicity and irregularities of the contour
Definition
Sonographically a rupture of a testicle looks
Term
epididymis
Definition
infection of the testis usually begins where?
Term
Lower UTI
Definition
Infection of the testis commonly caused by?
Term
epididymitis
Definition
inflammation or infection of the epididymis
Term
epididymitis
Definition
Most common cause of acute scrotal pain and tenderness
Term

enlargement of the epididymal head with decreased echogenicity secondary to edema

hyperemic flow

Definition
Sonographically acute epididymitis appears
Term
30mm
Definition
Transverse diameter of epididymitis may reach up to___?
Term
orchitis
Definition
infection that has spread to the testicle
Term
hypoechoic area adjacent to an enlarged epididymitis
Definition
Focal orchitis appears
Term
hydroceles and skin thickening
Definition
associated with orchitis
Term
epididymo-orchitis
Definition
infection of the epididymis and the testis
Term
hydrocele
Definition
collection of fluid located between the visceral and parietal layers of the tunica vaginalis or along the spermatic cord
Term
hydrocele
Definition
most common cause of painless scrotal swelling
Term
hematocele
Definition
blood collection in scrotal sac
Term
pyocele
Definition
pus filled collection within the scrotal sac
Term
Torsion
Definition
When testicle revolves one or more times on the short stalk of tunica vaginalis, which causes obstruction of blood flow to the testicle with resultant excruciating pain
Term
24 hours
Definition
necrosis of the torsed testicle happens within ____?
Term
bell clapper deformity
Definition
most common cause of torsion
Term
bell clapper deformity
Definition
there is no bare area and the testis is completely covered, which allows the testicle to move freely
Term
venous flow
Definition
Which is affected first and causes swelling in torsion?
Term
5-6 hrs
Definition
if surgery is performed within the first ___ of torsion,  the salvage rate is 80-100%.
Term
torsion
Definition
is  the most common cause of acute scrotal pain in adolescents and young adults
Term
spermatocele
Definition

cystic dilations of the efferent ductules, are benign cysts consisting of nonviable sperm.

Commonly caused by obstruction and are located in the head of the epididymis

Term
epididymal cysts
Definition

similar to spermatoceles, are caused by obstruction. Differ from spermatoceles in that they contain serous fluid, not nonviable sperm.

Most commonly found in the head

Term

well circumscribed and enechoic, within smooth walls, increased through transmission, and posterior enhancement

Average 2-5mm

Definition
spermatoceles  and epididymal cysts are sonographically seen
Term
Varicocele
Definition
abnormal dilation and tortuosity of the veins in the pampiniform plexus of the spermatic cord
Term
pampiniform plexus
Definition
network of veins that drains the testicles
Term
left side because the left gonadal vein drains in the left renal vein
Definition
Varicoceles happen more often on what side and why?
Term
primary varicocele
Definition
most common cause of infertility because associated with low sperm counts and decreased motility
