  2. History of infertility
  3. May have dull, aching scrotal pain
24
Q

How is a varicocele diagnosed?

A
  1. Diagnosis is usually clinical and made on physical exam
  2. Does NOT transilluminate
  3. Increases in size with valsalva: due to increased abdominal pressure
  4. Decreases in size when supine
25
Q

When should imaging studies be done in varicocele cases? What type of imaging?

A

In equivocal cases or in patients with large body habitus, scrotal ultrasound with color flow doppler imaging may be useful

26
Q

What is the tx for varicocele?

A
  1. Scrotal support
    - Mild varicocele where fertility is not a concern
  2. Surgical Repair
    - Ligate gonadal vein
    - A single vein is left open (vasal vein)
    - To restore or retain fertility
27
Q

Define Paraphimosis

A

Foreskin becomes trapped behind the corona for a prolonged period, a tight band of tissue forms around the penis

28
Q

What are the results/complications of the trapped foreskin in a paraphimosis?

A
  1. Initially impairs venous blood and lymphatic flow from the glans penis and prepuce
    - Edema of the glans
  2. As the edema worsens, arterial blood flow becomes compromised
  3. Eventually leads to gangrene or autoamputation of the distal penis
29
Q

What is the etiology of paraphimosis in infants and young children?

A

Usually results from self manipulation by the child or inappropriate retraction of the foreskin by the caretaker

30
Q

What is the etiology of paraphimosis in sexually active adolescents and adults?

A

Intercourse is a potential precipitant

31
Q

What is iatrogenic paraphimosis?

A

Follows cystoscopy or bladder catheterization if the foreskin is not reduced back over the glans penis by the medical provider

32
Q

What are the sxs of Paraphimosis?

A
  1. Penile pain & swelling
  2. Edema & tenderness of glans
  3. Painful swelling of distal retracted skin
  4. Constricting band of tissue proximal to head of penis
  5. Remainder of the penile shaft is unremarkable
33
Q

What is conservative tx for paraphimosis?

A
  1. Can often be reduced by manipulation by PCP, ER physician or Urologist
    A. Involves compressing the glans and moving the foreskin back to its normal position
    B. May need lubricant
34
Q

What are the surgical tx of paraphimosis?

A

The foreskin may need to be cut (dorsal slit procedure) or removed by circumcision

35
Q

How is paraphimosis prevented?

A
  1. Education of the patient &/or caregiver on the need to return foreskin over the glans after it has been retracted for Cleaning of the glans or After sexual activity
36
Q

Define phimosis

A

Inability to retract the distal foreskin over the glans penis
-Irritation or bleeding from the preputial orifice

37
Q

When is phimosis natural?

A

Physiologic phimosis occurs naturally in newborn males

38
Q

When is phimosis pathological?

A

Pathologic phimosis refers to inability to retract the foreskin after it was previously retractable or after puberty
-Usually secondary to distal scarring of the foreskin

39
Q

What is the pathophys of phimosis?

A
  1. Poor hygiene and recurrent episodes of balanitis lead to scarring of preputial orifices, leading to pathologic phimosis
  2. Forceful retraction of the foreskin leads to micro-tears that also lead to scarring and phimosis
40
Q

Why are elderly men at risk for phimosis?

A

Elderly personsare at risk of phimosis secondary to loss of skin elasticity and infrequent erections.

41
Q

What is the tx for phimosis?

A
  1. Rarely require emergency intervention
  2. Urology referral
    - Topical steroid cream
    - Stretching exercises with gentle retraction
42
Q

Define testicular torsion

A

Abnormal twisting of spermatic cord of testicle, thus compromising arterial blood supply, leading to ischemia

43
Q

What is the normal rotation of the testicles with contraction of the cremaster muscle?

A
  1. left testicle rotates counterclockwise 2. the right testicle rotates clockwise
44
Q

Where is testicular torsion more common in adolescents?

A

intravaginal torsion

45
Q

Where is testicular torsion more common in neonates?

A

Extravaginal torsion

46
Q

What is the prevalence and risk of testicular torsions?

A
  1. Greatest risk is during neonatal period and between 12-18 years
  2. More common in boys with Hx of cryptorchidism
  3. Infants with torsion of one testicle are at greater risk for torsion of other testicle
47
Q

What is a bell clapper deformity? What type of torsion is it asst. with?

A
  1. Incomplete attachment of testicle to scrotal wall
  2. Intravaginal torsion: Inappropriately high attachment of tunica vaginalis and abnormal fixation of muscle/fascia of spermatic cord
48
Q

what is the etiology of extravaginal torsion?

A

Loose attachment of tunica vaginalis to scrotal lining

-Results in spermatic cord rotation above testicle

49
Q

What are the complications of testicular torsion?

A
  1. Complete testicular infarction

2. Testicular atrophy

50
Q

What are the sxs of a testicular torsion?

A
  1. Abrupt onset excruciating pain in affected testicle
    -Usually middle of night or morning
  2. Edematous, elevated, ecchymotic scrotum
    (-) Prehn’s Sign (variable)
  3. Loss of cremaster reflex on affected side
  4. Abdominal pain
  5. Nausea/vomiting
51
Q

What diagnostic studies are indicated in testicular torsions?

A
  1. Doppler ultrasound of scrotum
    - Emergent
    - Absent blood flow and avascular testicle
    - Diagnostic
52
Q

What is the surgical tx for testicular torsion?

A
  1. Immediate surgical repair
    - 6 hr window
    - Orchiopexy: bilaterally attach testicle to the scrotum so it doesn’t move
    - Orchiectomy: loose a testicle permanently
53
Q

What is the conservation tx for testicular torsion?

A

Manual manipulation of testicle away from midline to improve blood flow before surgery
Not always possible

54
Q

What are the viability rates of the testicle over time?

A

Detorsion within 6 hours - 90% viability
Detorsion at 12 hours - 50% viability
Detorsion at 24 hours -10% viability
Detorsion after 24 hours - 0% viability

55
Q

Define orchiopexy

A

Fixation of a viable testicle to scrotum

Prophylactic fixation of contralateral testicle

56
Q

Define Orchiectomy

A

Excision of nonviable testicle

Preserves fertility in other testicle
