22
Q

If you cannot feel above a scrotal mass, what is the mass most likely to be?

23
Q

In which decade is the peak incidence of testicular torsion?

A

2nd decade of life

24
Q

How does testicular torsion typically present?

A

Acute unilateral testicular pain +/- nausea/vomiting

25
Where else may pain be felt by someone with testicular torsion, other than the testicle itself?
Abdomen
26
Absence of the cremasteric reflex on examination of a testicle is suggestive of what diagnosis?
Testicular torsion
27
What investigation can be used to demonstrate testicular torsion, but is usually not performed at the expense of surgical exploration?
Doppler ultrasound
28
The management for testicular torsion is urgent surgery. What surgical procedures are patients consented for?
Bilateral ochidopexy and possible orchidectomy
29
The outcome is best if testicular torsion is surgically fixed within what timeframe?
< 6 hours
30
Torsion of the appendage testis (hydatid of Morgagni) is typically seen in individuals of what age?
7 - 12
31
How may torsion of the appendage testis (hydatid of Morgagni) be differentiated clinically from testicular torsion?
Less pain, present cremasteric reflex, possible blue dot sign
32
How is torsion of the appendage testis (hydatid of Morgagni) managed?
It will resolve spontaneously
33
Where does an epididymal cyst lie in relation to the testis?
Above and behind
34
When should an epididymal cyst be removed?
Only if symptomatic
35
The presence of milky fluid in the testis suggests the development of what?
Spermatocele
36
What is the most likely cause of epididymo-orchitis in those aged < 35? How should this be treated?
Chlamydia infection (+/- gonorrhoea) - treat with PO doxycycline and IM ceftriaxone
37
What is the most likely cause of epididymo-orchitis in those aged > 35? How should this be treated?
E. coli infection - treat with PO ofloxacin/ciprofloxacin
38
Along with testicular pain, what are some other symptoms that may be present in epididymo-orchitis?
Frequency and dysuria
39
What imaging investigation can be used to identify epididymo-orchitis? What will it show?
Doppler US - will show increased blood flow
40
What additional investigation should be performed in those aged < 35 with epididymo-orchitis?
First pass urine sample PCR for chlamydia
41
How long should antibiotics be given for for epididymo-orchitis?
2-4 weeks
42
What is a varicocele?
A dilation of veins of the pampiniform plexus
43
95% of varicoceles occur on which side?
Left
44
A 'bag of worms' appearance of the testis is suggestive of what diagnosis?
Varicocele
45
When do varicoceles require treatment?
Only when they are symptomatic
46
Having an undescended testis comes with a 40x increased risk of developing testicular cancer. This risk may be reduced if orchidopexy is performed before what age?
10 years
