Q

What is the anatomical classification of hydroceles?

A
  1. Vaginal = accumulation in the tunica vaginalis that doesnt extend up the cord
  2. Congenital = proximal part of processus has not obliterated and the sac communicates directly with the peritoneum
  3. Infantile = processus is obliterated at the deep ring but still extends up the cord
  4. Hydrocele of the cord = fluid accumulates around the ductus deferens, testicular traction will pull it inferiorly, can be hard to distinguish from an inguinal hernia

Q

What is the aetiological classification of hydroceles?

A
  1. Primary = Caused by a patent processus vaginalis, commonest type, young men + large + tense
  2. Secondary = Vaginal type can be caused by a variety of pathologies e.g. testicular tumours, trauma, torsion, epididymo-orchitis

Q

What is the management of hydroceles?

A
  1. Non-surgical = watch and wait (ensure no Ca), aspiration (symptomatic relief only as will accumulate)
  2. Surgical = Lord’s repair (plication of tunica vaginalis), Jaboulay’s repair (eversion of the sac)

Q

How do you classify varicocoeles?

A
  1. Primary = 15% young men, often around puberty, anatomical cause (?nutcracker syndrome), disappears when pt lies supine
  2. Secondary = suddenly appearing in older men, can be sinister, retroperitoneal disease affecting the testicular vein (e.g. renal cell carcinoma extending into L renal vein), doesnt disappear when pt lies supine

17
Q

What is nutcracker syndrome?

A

Compression of the Left Renal Vein between the AA and SMA

18
Q

What is SMA syndrome?

A

Compression of the third part of the duodenum by the AA and SMA

19
Q

What are the symptoms of a varicocoele?

A
  1. Dragging sensation exacerbated by exertion

2. Subfertility (commonest surgically correctable cause)

20
Q

Why do 98% varicocoeles occur on the left? (x4)

A
  1. Left testicular vein is more vertical where it joins the left renal vein compared to the obliquity of the right testicular vein where it joins the IVC
  2. Left renal vein can be compressed by the colon
  3. Left testicular vein is longer than the right
  4. Left testicular vein often lacks a terminal valve to prevent backflow
21
Q

What are the management options for a varicocoele?

A
  1. Non-surgical = scrotal support, transfemoral radiological embolisation of the testicular vein
  2. Surgical = Palomo operation, laparoscopic approach also possible
22
Q

What is the commonest malignancy in men 15-45y/o?

A

Testicular tumours

23
Q

What are the tumour markers for testicular tumours?

A

AFP, βHCG, Placental ALP

24
Q

How do you classify testicular tumours?

A
  1. Germ cell tumours (95%) –> Seminomas (50%), Teratomas
  2. Yolk sac tumours = commonest testicular tumour in children
  3. Choriocarcinoma
  4. Leydig or Sertoli cell (may secrete oestrogens –> gynaecomastia)
  5. Lymphoma (NHL is commonst testicular mass >60y/o)
25
Q

What kind of tumours do young troopers get?

A

Teratomas

26
Q

What kind of tumours do old sergeants get?

A

Seminomas

27
Q

What are the leading causes of epididymo-orchitis in <35y/o?

A

STIs = C. trachomatis and N. gonorrhoeae

28
Q

What is the leading cause of epididymo-orchitis in >35y/o?

A

E.coli

29
Q

What does it means if one is Prehn’s sign +ive?

A

There is relief of pain upon elevation of the scrotum, a sign of epididymo-orchitis

30
Q

What are the 4 key questions to ask when examining a scrotal lump?

A

ATPP

  1. Can you get above it?
  2. Is it tender?
  3. Is the testis palpable separately?
  4. Does it transilluminate?
31
Q

What is a scrotal mass you can’t get above?

A

An inguinoscrotal hernia

32
Q

Scrotal Lump you can get above
Separately palpable?: No
Transilluminate?: No

A

HOT
Haematocoele
Orchitis
Tumour

33
Q

Scrotal Lump you can get above
Separately palpable?: No
Transilluminate?: Yes

A

Hydrocoele

34
Q

Scrotal Lump you can get above
Separately palpable?: Yes
Transilluminate?: No

A 
VESS
Varicocoele
Epididymitis 
Spermatocoele
Sperm granuloma
35
Q

Scrotal Lump you can get above
Separately palpable?: Yes
Transilluminate?: Yes

A

Epididymal cyst

36
Q

What is the management of a hydrocoele?

A
  1. Non-surgical = watch and wait (ensure no Ca) + aspiration (symptom relief only as will accumulate)
  2. Surgical = Lord’s repair (plication of the tunica vaginalis) + Jaboulay’s repair (eversion of the sac)
37
Q

What is the management of a epididymal cyst?

A
  1. Non-surgical = if cyst isnt troublesome it shouldnt be removed due to the risk of operative damage and subsequent post-op fibrosis –> subfertility
  2. Surgical = very large of painful cysts can be removed, excision of the entire epididymis may be indicated to prevent the recurrence of painful cysts
38
Q

What is the management of a varicocoele?

A
  1. Non-surgical = scrotal support or transfemoral embolisation of the testicular vein
  2. Surgical = often advised as the problem usually gets worse with age and can cause subfertility –> Palomo operation (laparoscopic approach also possible)
39
Q

What is the management of a testicular tumour?

A

All testicular tumours are treated with orchidectomy (groin incision with early clamping of spermatic cord to prevent seeding)

40
Q

Mx of epididymal cyst?

A
  1. Non-surgical = if not troublesome, shouldnt be removed
  2. Surgical = very large or painful cysts can be removed, excision of the entire epididymis may be indicated to prevent the recurrence of painful cysts
41
Q

Seminoma Mx?

A
  1. Early = DXT to para-aortic nodes

2. Late = DXT + combination chemo

42
Q

Teratoma Mx?

A
  1. Early = observation

2. Late = combination chemo (BEP Bleomycin, Etoposide, Cisplatin)
