Q

Why are most varicocele’s found on the left?

A
  1. Increased pressure in left testicular vein.
  2. As it drains perpendicular into left renal vein.
  3. Hence turbulent flow

Q

Compare pressure in the left and right testicular vein.

A

Right testicular vein drains at a lesser angle directly into IVC.
Hence lower venous pressure than left testicular vein.

Q

Cough impulse

Epididymo-orchitis
If epididimitis spreads to testes - gradual onset - dull ache or pain
26
State some causes of groin lumps
``` Lymphocele Ectopic testes Saphena Varix Psoas Abscess Femoral aneurysm Lipoma Lymph node Inguinal and femoral hernia ```
27
Describe how a lymphocele may form?
Following femoral artery surgery in groin. Disruption of local lymphatics. Local collection of lymphatic fluid forms lump. Can be aspirated.
28
Ectopic testes
Testes is absent from scrotum
29
How may you diagnose an ectopic testes?
Feel alongside line of inguinal canal ligament. | Should detect and undescended testes.
30
Saphena varix
Bluish tinge. Has cough impulse. Disappears when lying down. Varicose veins may be present.
31
Psoas abscess
In psoas muscle Caused by Crohn's or Tb Causes fixed flexion of hip
32
What would you inspect a scrotum for?
Lumps Scars Swelling Get patient to cough
33
How would you palpate the scrotum / testes?
1. Place hand over lump, get patient to repeat cough reflex, in order to feel movement. 2. Check both sides for less obvious bilateral hernia 3. Start on unaffected side 4. Palpate along line of inguinal ligament to identify an undescended testes
34
What is a reducible hernia?
A hernia with a bulge that flattens out when you lie down or push against it gently.
35
How may you distinguish between a direct and indirect hernia?
1. Ask patient to reduce lump 2. Cover deep inguinal ring covered with 2 fingers. 3. Ask patient to cough IF - Lump comes out (direct) - Stays in place (Indirect)
36
What would be observed is you trans-illuminated a hernia?
Nothing. | Hernia's do not trans-illuminate
37
What is the surgical difference between direct and indirect hernias?
Direct hernia arises laterally to inferior epigastric artery. Arises through deep ring.
38
How would you identify an undescended testes?
Palpate along the line of inguinal ligament to identify an undescended testis. Use the cough impulse.
39
You are inspecting a patient. You can feel above the lump. What could it be?
Hydrocele Tumor Varicocele Epididymal cyst
40
On inspection of a patient you realise you can't feel above the lump, this could indicate...
Presence of hydrocele of cord | Indirect inguinal hernia
41
What kind of lumps are transilluminable?
Hydrocele Epididymal cyst Hydrocele of cord
42
What kind of lumps are definitely not transilluminable?
Tumour | Indirect inguinal hernia
43
What is schistosomiasis
Water bourne parasite | - gives rise to squamous cell carcinoma
44
Uraemia
Characteristic fishy smell on tongue
45
Bruit
Abnormal sound heard over upper abdomen
46
Possible causes of bruit
Renal artery stenosis Aneurysm of renal artery Arteriovenous fistula
47
Describe scrotal pain
May be referred to groin or abdomen Result of stretching of albuginea
48
Strangury
Repeated desire to pass urine but with little to show for it other than pain related to urethra or penile tip.
49
What is renal agenesis?
Kidney either absent or underveloped
50
Renal dysplasia
One kidney in newborn is multicystic, irregularly lobulated mass of cysts. Usually absent ureter.
51
Potter's syndrome
Bilateral renal agenesis | - can also occur due to infantile polycystic kidney disease, renal hypoplasia and obstructive neuropathy
52
Renal hypoplasia
One small kidney with one larger than normal
53
How might renal hypoplasia differ from renal dysplasia?
Kidney otherwise morphologically normal. Normal residual parenchyma. Smaller calyces, lobule, papillae
54
Supernumerary kidney
3rd kidney
55
Describe common position of horseshoe kidney?
Often fixed at lower pole. Positioned lower. Central part just below inferior mesenteric artery
56
Ectopic kidney
Kidney does not ascend properly, found in pelvis
57
Ureteral atresia
Ureter maybe absent or fail to extend to bladder
58
Epispadia
Rare, congenital abnormality involving the opening of urethra. Urethra opens on top of penis as oppose to tip.
59
Lymphatic drainage of scrotum
Inguinal nodes
60
Where do the right and left testicular veins drain into?
LEFT: Pampiniform plexus drain into renal vein on the left. RIGHT: IVC on right
61
State some conditions affecting foreskin
Balanoposthitis Phimosis Paraphimosis
62
Balanoposthitis
Inflammation of the head of the penis and the foreskin
63
Symptoms of balanoposthitis
Redness, swelling and soreness around head of penis or foreskin. Thick discharge under foreskin. Rash on the penis Itchiness Unpleasant odour Pain when urinating
64
Causes of balanoposthitis
Irritation caused by smegma, Thrush. Bacterial infection caused by streptococcal bacteria.
65
Phimosis
Condition where foreskin is too tight to be pulled back over head of penis.
66
Paraphimosis
When foreskin cannot be returned to its original position after being retracted. - in extreme cases penile head may become gangrenous - emergency reduction is indicated
67
Difference between Epispadias and Hypospadias
Epispadias: congenital absence of upper wall of urethra, results in urethral meatus on dorsum of penis. Hypospadias: urethral opening appearing on underside of penile shaft or on the perineum
