Brief (to candidate)
You will assess a patient with a presentation consistent with Hydrocele.
You have 8 minutes to take a focused history, outline examination, investigations, and management including red flags.
Clinical context
Hydrocele is an abnormal collection of serous fluid within the tunica vaginalis of the testis (vaginal type) or along a patent processus vaginalis (congenital type). It presents as painless, gradually enlarging scrotal swelling that is positive on transillumination and that the examiner can get above (confirming it is scrotal, not inguinal). Congenital hydrocele (patent processus vaginalis) is common in infants and resolves by age 2 in over 90 percent of cases. Adult hydrocele is idiopathic or secondary to infection, trauma, tumour, or filariasis. The clinical skill is excluding the dangerous mimics — inguinal hernia (cough impulse positive, reducible, cannot get above), testicular tumour (h
Candidate tasks
- Clarify onset, severity, associated features, and red-flag symptoms.
- State focused examination priorities.
- List first-line investigations and any named score/criteria.
- Give immediate resuscitation steps.
- Outline definitive management with doses/routes where standard.
- Name complications and disposition (ward / HDU / theatre / discharge safety-net).
- Mention one special-population modifier (pregnancy, child, elderly, CKD).
Examiner checklist
| Domain | Pass behaviours |
|---|---|
| Definition | Correct working diagnosis language |
| Assessment | Focused, prioritised, red flags sought |
| Investigations | Appropriate first-line + interpretation |
| Emergency care | ABC / time-critical actions first |
| Definitive care | Specific drugs/procedures, not generic phrases |
| Safety | Sudden onset painful scrotal swelling in a young male - exclude testicular torsi |
| Safety | Scrotal swelling that does NOT transilluminate and feels heavy - exclude testicu |
| Safety | Rapidly enlarging hydrocele in an older man - underlying testicular malignancy u |
| Communication | Clear plan and safety-netting |
Model outline
Lead with the working diagnosis and life threats. Resuscitate before definitive tests when unstable. Use guideline-standard therapy with named agents and doses. Document escalation criteria and follow-up. A safe candidate is specific, structured, and never delays critical care for non-urgent imaging.
