Penis/Testes Exam Flashcards
The shaft of the penis is formed by three columns of vascular erectile tissue which are:
The corpus spongiosum, (containing the urethra)
and the two corpora cavernosa
The corpus spongiosum forms the _______ of the penis, ending in the cone-shaped glans with its expanded base, or ________
bulb; corona
In uncircumcised men, the glans is covered by a loose, hood-like fold of skin called the _______, or foreskin, where ________, or secretions of the glans, may collect
prepuce; smegma
The urethra opens into the vertical, slit-like ___________________
urethral meatus
The _________ are ovoid, somewhat rubbery
structures approximately 4.5 cm long
testes
Which testes lies lower than the other?
left is usually slightly lower than the right
What does the testes produce?
spermatazoa and testosterone
The ________ is a loose, wrinkled pouch divided into two compartments, each containing a testis
scrotum
Covering the testis, except posteriorly, is the serous membrane of the _________________
tunica vaginalis
On the posterolateral surface of each testis is the softer comma-shaped __________;
epididymis
What does the epididymis do?
the epididymis provides a reservoir for storage, maturation, and transport of sperm
The _____________, a cordlike structure, begins at the tail of the epididymis
vas deferens
The vas deferens ascends within the scrotal sac (as the _______________) and passes through the external inguinal ring on its way to the abdomen and pelvis
spermatic cord
Behind the bladder, the spermatic cord is joined by the duct from the ___________ and enters the urethra within the ______________
seminal vesicle; prostate gland
The basic landmarks of the groin are the ______________________, the ______________, and the __________________
ASIS, pubic tubercle, and the inguinal ligament
The _______________, which lies above and parallel to the inguinal ligament, forms a tunnel for the vas deferens
inguinal canal
The exterior opening of the tunnel is the ___________________; the internal opening of the canal is the ______________________
external inguinal ring; internal inguinal ring
What is an indirect inguinal hernia?
develop at the INTERNAL inguinal ring, where the spermatic cord exits the abdomen
What is a direct inguinal hernia?
they arise more medially from weakness in the floor of the inguinal canal and are associated with straining and heavy lifting, it is found at the EXTERNAL inguinal ring
When checking for hernias, the patient should ______ and the examiner should ________ on a chair or stool
stand; sit
When the patient retracts the prepuce, you may see a cheesy, white material called what?
smegma
Compress the _____ gently between your index finger above and thumb below to open the _______________ and allow inspection for discharge (normally there is none)
glans; urethral meatus
If the patient has reported a discharge that you are unable to see, what should you do?
ask him to milk the shaft of the penis from its base to the glans. This maneuver may bring some discharge to the urethral meatus for appropriate examination
What is the soft, nodular, cordlike structure at the back of the testicle?
epididymis
What can the patient do to make it easier to detect hernias?
stand, strain and bear down
When evaluating a possible scrotal hernia, If a large scrotal mass is found, ask the patient to lie down. If the mass disappears, it is a ________
hernia
If a scrotal mass remains when they lay down, what can you do to check if it is a hernia?
Listen to the mass with a stethoscope. If bowel sounds are heard, it is a hernia.
What can you do to a scrotal mass to see if it is a hernia?
Shine a strong light from behind the scrotum through the mass (transillumination). If a red
glow is observed, it is probably not a hernia
How do you access for hernias?
Use right hand to press into inguinal canal on right and vise versa with left hand and left side. Ask patient to bear down to see if a hernia touches your finger.
What is the normal write-up for a male GU exam?
Circumcised male. No penile discharge or lesions. No scrotal swelling or discoloration. Testes descended bilaterally, smooth, without masses. Epididymis non-tender. No inguinal or femoral hernias.
Which of the following statements about hernias is true?
A.) Indirect inguinal hernias are the most common form of hernia
B.) Femoral hernias are the least common form and are more common in women
C.) Direct inguinal hernias are more common in men over age 40
D.) Indirect inguinal hernias originate above the inguinal ligament near its midpoint
F.) All of the above
ALL OF THE ABOVE!
A 21-year-old male presents complaining of a “nodule” on the back of his left testicle found during testicular self-examination. On examination, you find both testicles to be of normal size, shape, and consistency. On the back of the left testicle in the area of the “nodule,” you find a soft, nodular, tubelike structure with no areas of abnormal tenderness. Your most likely diagnosis is:
Acute epididymitis
Cyst of the epididymis
Normal epididymis
Carcinoma of the epididymis
Normal epididymis. The epididymis is located on the superior, posterior surface of each testicle. It feels nodular, soft, and cordlike and should not be confused with an abnormal lump.
single or multiple papules or plaques of variable shapes; may be round, acuminate (or pointed), or thin and slender. May be raised, flat, or cauliflowerlike (verrucous).
genital warts (condylomata acuminata)
What is the causative organism for condylomata?
HPV, usually from subtypes 6 and 11
How common is the carcinogenic form of condylomata?
rare, approx. 5-10% of all anogenital warts, incubation is weeks to months, infected contact also may have no visible warts
Where can condylomata show?
penis, scrotum, groin, thighs, anus, usually it is asymptomatic, occasionally cause itching and pain- may disappear without treatment
Small scattered or grouped vesicles, 1-3 mm in size, on glans or shaft of penis. Appear as erosions if vesicular membrane breaks.
genital herpes simplex
What type of herpes simplex usually occurs?
herpes simplex virus 2 (90%), a double stranded DNA virus. 2-7 days incubation
What are the associated symptoms of herpes besides the vesicles?
primary episode may be asymptomatic; recurrence usually less painful and of shorter duration. Associated with fever, malaise, headache, arthralgias, local pain and edema, lymphadenopathy
What do you need to distinguish herpes from?
genital herpes zoster (usually older people with dermatome distribution), candidiasis
