Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Rapid Clinical Assessment
Document symptom onset time - critical for prognosis
- Symptom onset time (critical!)
- High-riding testis with transverse lie
- Absent cremasteric reflex (sensitive)
- Tender, swollen hemiscrotum
- Nausea/vomiting common
- May have lower abdominal pain
03Decision Clinical Suspicion High?
Classic presentation: acute pain + high-riding testis + absent cremasteric reflex
04Action Immediate Urology Consult
Do NOT delay for imaging if clinical suspicion high
- Call urology STAT
- Prepare for OR
- NPO status
- IV access
- Consent for exploration ± orchiectomy
05Action Attempt Manual Detorsion
If urology/OR not immediately available
- Rotate testis medial to lateral ('open book')
- Turn 180° at a time, reassess
- May require 1-3 full rotations
- Success = pain relief + testis descent
- If pain increases, try opposite direction
- Does NOT replace surgical exploration
06Warning ⚠️ TIME-CRITICAL EMERGENCY
Salvage rates by time from symptom onset (EAU 2024)
- <6 hours: 90-100% salvage rate
- 6-12 hours: ~50% salvage rate
- 12-24 hours: ~10% salvage rate
- >24 hours: Near 0% salvage
- Target: Immediate surgery (EAU Strong Recommendation)
07Action Surgical Exploration
Definitive management - do not delay
- Scrotal incision and delivery of testis
- Detorsion and assessment of viability
- Warm saline wrapping
- If viable → orchiopexy
- If non-viable → orchiectomy
- Contralateral orchiopexy (bilateral bell-clapper)
08Decision Testis Viable?
Assess color, bleeding, Doppler after detorsion
09Action Bilateral Orchiopexy
Fix both testes to prevent recurrence
- 3-point fixation with non-absorbable suture
- Fix contralateral testis (bilateral bell-clapper)
- Place in dartos pouch
10Outcome Testis Salvaged
Follow-up: monitor for atrophy, fertility counseling
11Action Orchiectomy + Contralateral Orchiopexy
Non-viable testis removal
- Remove necrotic testis
- Fix contralateral testis
- Discuss future prosthesis option
- Counsel re: fertility (usually preserved)
12Outcome Testis Lost
Counsel patient: single testis adequate for fertility/hormones
13Action Doppler Ultrasound
Only if diagnosis uncertain - do NOT delay surgery
- Absent/decreased blood flow suggests torsion
- Whirlpool sign (twisted cord)
- Sensitivity 82-100%, Specificity 97-100%
- Normal flow does not rule out intermittent torsion
- If positive or equivocal → surgical exploration
- Path rejoins step 04Shared downstream outcome
14Action Consider Alternative Diagnoses
If ultrasound shows normal flow
- Torsion of appendix testis/epididymis
- Epididymitis/orchitis
- Incarcerated inguinal hernia
- Trauma/hematocele
- Idiopathic scrotal edema

Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Does not address neonatal testicular torsion
- Intermittent torsion may have atypical presentation
- Doppler ultrasound sensitivity varies by operator
- Does not address torsion of testicular appendages
- Time of symptom onset may be unclear in some cases
