Testicular Torsion

Testicular torsion is a surgical emergency with time-critical salvage rates: ~100% at 6h, ~50% at 12h, ~10% at 24h. Clinical diagnosis is sufficient to proceed to theatre — never delay for Doppler USS if the clinical picture is clear. Alert theatre…

Time-to-OR Salvage Targets

The pathway

1 · Clinical diagnosis

Sudden severe testicular pain: often wakes from sleep, may have nausea/vomiting
High-riding testis: cremasteric reflex absent (most reliable sign)
Horizontal lie of testis (bell-clapper deformity): lies transversely
Absent cremasteric reflex: present in normal testes (stroking inner thigh elevates testis)
Swollen, erythematous scrotum: may develop rapidly
Recent trauma does not exclude torsion

2 · Do NOT wait for Doppler USS

If clinical diagnosis of torsion is clear → proceed directly to emergency theatre
Doppler USS can give false negative in early torsion (arterial flow may still be present)
Ordering USS introduces harmful delay in the highest-risk window
Only use Doppler if diagnosis is genuinely uncertain and time allows (<4h since onset)

3 · Document time of symptom onset

Ask patient, family, or witnesses for exact time pain started
Time of onset determines urgency of theatre slot and salvage probability
Document in notes and on theatre booking form
Inform theatre of time of onset — this is a time-critical emergency

4 · Bell-clapper deformity and bilateral risk

Bell-clapper deformity (tunica vaginalis covers epididymis and posterior testis): predisposes to torsion
Bilateral in approximately 80% of affected males
Therefore both testes must be fixed at surgery regardless of which is torted
Contralateral torsion risk is real even after unilateral presentation

5 · Senior surgical review and theatre

Bleep surgical registrar/consultant immediately
Inform theatre coordinator and anaesthetist urgently
Consent: explain bilateral orchidopexy and possible orchidectomy if non-viable
Aim for theatre within 1 hour of presentation if within 6h of onset
Do not wait for morning list if presenting at night

6 · Intra-operative management

Explore scrotum: detorse the affected testis
Warm saline swabs applied for 10 minutes: assess viability (pink colour returning = viable)
Viable testis: bilateral orchidopexy (3-point fixation with non-absorbable suture)
Non-viable testis: orchidectomy + contralateral orchidopexy
Document findings: time to detorsion, colour change, decision made

7 · Medicolegal documentation

Document exact time patient presented, time surgical review, and time to theatre
Record clinical findings (cremasteric reflex, lie of testis, Doppler if done)
Document decision-making: why theatre proceeded without Doppler (if applicable)
Record consent discussion including orchidectomy possibility
Testicular torsion is a high medicolegal risk case — contemporaneous notes are essential

Drugs

Drug	Dose	Route	Notes
Morphine	10mg	IV	Adequate analgesia. Titrate. Do not withhold analgesia while awaiting theatre.
Ondansetron	4mg	IV	Antiemetic — nausea and vomiting common with severe testicular pain.
Co-amoxiclav	1.2g	IV	If secondary infection suspected (orchitis picture) or post-orchidectomy. Not routine for torsion alone.

When to escalate

Symptom duration >6h — urgent theatre regardless, viable tissue may still be present,Undescended testis with pain — ectopic torsion, higher index of suspicion required,Failed manual detorsion (bridge only, not definitive) — theatre immediately,Missed diagnosis with subsequent atrophy — urology follow-up, medicolegal documentation
