Q

Why is it important to check whether the mass is separate from the testicle?

A

It allows you to elicit whether the problem is in the testicle itself, or with other structures within the scrotum

Q

What important information about the swelling does transillumination allow you to elicit?

A

It tells you whether the swelling is caused by a collection of fluid (e.g. a cyst) or a solid mass (e.g. a tumour)

Q

What is the main risk factor for testicular cancer?

A

Undescended/maldescended testicle

19
Q

What is the term given to the operation that places an undescended testicle in its correct place?

A

Orchidopexy

20
Q

To which lymph nodes do the testes drain?

A

Para-aortic lymph nodes

21
Q

To which lymph nodes does the scrotum drain?

A

Inguinal lymph nodes

22
Q

List some systemic symptoms of malignancy.

A

Fever
Weight loss
Night sweats

23
Q

What is the investigation of choice for any scrotal mass?

A

Ultrasound scan

24
Q

What are the main tumour markers for testicular cancer?

A

a-fetoprotein (AFP)
B-HCG
Lactate dehydrogenase (LDH)

25
Q

Describe the characteristic features of an epididymal cyst.

A

Distinct from the testis (superior and posterior to it)
Can get above the swelling
Fluctuant and transilluminable
Often multiple or multiocular, and may be bilateral

26
Q

What is the term given to a subtype of epididymal cyst that contains milky fluid?

A

Spermatocoele

27
Q

Describe what a varicocoele feels like on palpation.

A

It feels like ‘a bag of worms’

28
Q

What is a varicocoele?

A

It is made up of dilated, tortuous veins of the pampiniform plexus

29
Q

How do varicocoeles vary in size?

A

They respond to changes in venous pressure so they can increase in size towards the end of the day (due to venous pooling) or following strenuous exercise
When the patient lies down, the varicocoele will not be palpable

30
Q

What conservative measure can be taken to reduce discomfort caused by varicocoeles?

A

Scrotal support (e.g. jock strap or tighter pants)

31
Q

If the varicocoele is painful, surgical intervention may be taken. List some treatment options.

A

Embolisation
Surgical ligation
Sclerotherapy

32
Q

What is a hydrocele?

A

A collection of fluid within the tunica vaginalis

33
Q

What are the two types of hydrocele?

A

Primary (idiopathic)

Secondary (to a testicular insult e.g. trauma, infection, cancer)

34
Q

In what age groups do secondary hydroceles tend to occur?

A

Men ages 20-40 yrs because they are at greatest risk of having one of the initiating pathologies

35
Q

How do you treat hydroceles?

A

Secondary – treat the cause

Primary – aspirate the fluid or undergo surgery

36
Q

What usually causes epididymo-orchitis?

A

Acute infections of the testes and epididymis usually arise in the urinary tract or as STIs and ascend via the vas deferens

37
Q

List some investigations for epididymo-orchitis.

A

Blood cultures – if the patient is septic, it is important to identify the causative organism
HIV test
Urine dipstick – look for signs of UTI (e.g. leucocytes and nitrites)
Urine MC&S – identify the causative organism
Urethral swab and GUM screen

38
Q

What are the two most common types of testicular tumours and which age groups do they occur in?

A
  • Teratomas = 20-30

Seminoma = 30-50

39
Q

Which side are varicoceles more common in?

A

Left side

40
Q

Which pathogen is most likely to cause epididymo-orchitis in <35yr olds?

A

STIs:

  • Chlamydia trachomatis
  • Neisseiria gonnorhoea
41
Q

Which pathogen is most likely to cause epididymo-orchitis in >35yrs olds?

A

UTIs:

- E. coli

42
Q

Which pathogen might you consider in a boy who presented to his GP with a swelling adjacent to his jaw 8 days ago, and now presents with a swollen testis?

A

Mump

Mumps orchitis

43
Q

Which type of hernia are inguino-scrotal hernias? Direct, indirect, femoral, umbilical

A

They are almost always Indirect inguinal hernias
