Q

What do the risk factors for epididymo-orchitis depend on?

A

The underlying cause - STI or UTI

22
Q

What are the risk factors for non-enteric epididymo-orchitis?

A
  • MSM
  • Multiple sexual partners
  • Known contract of gonorrhoea
23
Q

What are the risk factors for enteric epididymo-orchitis?

A
  • Recent instrumentation or catheterisation
  • Bladder outlet obstruction
  • Immunocompromised
24
Q

How does epididymitis usually present?

A

Unilateral scrotal pain and swelling.

Fever and rigors can also be present

25
What other symptoms may be present with epididymo-orchitis?
Symptoms secondary to underlying cause, e.g. dysuria, storage LUTS, urethral discharge
26
What may be found on examination in epididymo-orchitis?
Epididymis +/- testis will be very tender on palpation, and may be associated hydrocele
27
What specific tests can be used in epididymitis?
- Cremasteric reflex | - Prehn's sign
28
What happens to the cremastic reflex in epidiymitis?
Nothing - it is in tact
29
What does a positive Prehn's sign in epididymitis?
Suggestive of epididymitis
30
How is Prehn's sign elicited?
The patient is supine and scrotum is elevated by examiner - positive is when pain is relieved by elevation
31
What is the main differential of epididymitis?
Testicular torsion
32
How does the presentation of testicular torsion differ from epididymitis?
In torsion, pain is more sudden onset and severe, and absence of LUTS
33
What can aid in the diagnosis of testicular torsion?
Dopper US (but if any significant suspicion of torsion, urgent scrotal exploration)
34
What are the other differentials for epididymitis?
- Testicular trauma - Testicular abscess - Epididymal cyst - Hydrocoele - Testicular tumour
35
What investigations may be done in suspected epididymitis?
- Urine dipstick - First void urine sent for NAAT - Routine bloods
36
When should first-void urine be done in suspected epididymitis?
Suspected non-enteric epididymitis
37
What may be warranted depending on history in suspected non-enteric epididymitis?
Further STI screening
38
What routine bloods should be done in epididymitis?
- FBC | - CRP
39
Describe the role of ultrasound imaging in suspected epididymitis?
Diagnosis is usually clinical oen, but ultrasound imaging of testes via US doppler may be useful to confirm diagnosis and rule out any complications, e.g. testicualr abscess
40
On what basis can the majority of patients with epididymitis be managed?
Outpatient
41
When may patients with epididymitis need to be managed as inpatient?
- Evidence of systemic infection - Uncontrolled pain - Needs further investigation
42
What should be involved in the initial management of epididymitis?
- Appropriate antibiotic therapy - Sufficient analgesia - Bed rest - Scrotal support - Abstain from sexual activity
43
What is the first line antibiotic for enteric epididymitis?
Ofloxacin PO BD for 14 days
44
What is the first line antibiotic for STI epididymitis?
Ceftriaxone 500mg IM single dose
45
How long should patients with epididymitis abstain from sexual activity?
Until antibiotic course is completed and symptoms resolve
46
What counselling should patients with STI epididymitis get?
Appropriate barrier contraception to reduce the risk of sexually transmitted infections
47
What follow up is required with epididymitis?
Routine follow up not typically recommended, but patient should seek further assessment if symptoms do not resolve or deteriorate
48
What may be required for management of chronic epididymitis?
Orchiectomy
49
How quickly do symptoms typically resolve in epididymitis?
Within 48 hours of starting abx
50
What complications may arise from epididymitis?
- Reactive hydrocele formation - Abscess formation - Testicular infarction
