1. Introduction, explanation, consent, wash hands.

2. General inspection: uncomfortable, pain/distress, sweating.

3. Vitals signs:
• HR.
• BP.
• RR.
• Temp - may be febrile.
• BMI.

4. Abdomen:
• Inspection - previous scars, skin lesions, abdominal distension, prominent veins, visible masses/lump/pulsations, visible peristalsis.
• Palpation - light and deep (tenderness - rebound, guarding, rigidity), organomegaly, paraortic lymph nodes, inguinal lymph nodes.
- Tests for peritonism - rebound tenderness, cough, jump on spot.
• Percussion
• Auscultation - bowel sounds.

5. Genitals:
• Inspection (standing and supine): erythema, swelling, trauma/deformity, sores, ulcers, rashes, discharge, asymmetry (elevated/horizontal in torsion).
• Palpation - tenderness, warmth, isolation of structures - testes, spermatic cord, epididymis (tenderness/thickness). Any lumps/masses - can you palpate above them (inguinal hernia).
• Transillumination test - hydrocele.

3

What is your provisional and differential diagnoses?

• Provisional diagnosis: Epididymo-orchitis.
• DDx:
- STD.
- Hernia (inguinal).
- Torsion.
- Appendicitis.
- Epididymal cyst.
- Hydatid of Morgagni (remnant of Müllerian duct - epididymal appendage).

4

What investigations would you carry out on this patient?

• First-catch urine → Urine PCR - chlamydia, gonorrhoea, mycoplasma genitalium.
• FBC.
• Bloods - Hep B/C, HIV, syphilis.
• Uretheral swab - if discharge.
• Doppler USS may demonstrate lack of blood flow to testis, as may isotope scanning. Only perform if diagnosis is equivocal - do not delay surgical exploration. Time dependent (<6 hours) - shows no flow in testicular artery.

5

What treatment does this patient require?

• If <35 years, doxycycline 100mg/12h (covers chlamydia, treat sexual partners).
• If gonorrhoea suspected, add ceftriaxone 500mg IM stat.
• If >35 years (mostly non-STI), associated UTI is common so try ciprofloxacin 500mg/12h or ofloxacin 200mg/12h. Antibiotics should be used for 2-4 weeks.
• Also analgesia, scrotal support, drainage of any abscess.
