Testicular TorsionNCLEX cheat sheet

Testicular torsion is twisting of the spermatic cord that cuts off blood supply to the testicle, producing sudden severe testicular pain and swelling.

Signs

  • SUDDEN severe testicular pain
  • Swollen, high-riding testis
  • Absent cremasteric reflex, N/V

Report

  • SURGICAL EMERGENCY → detorsion
  • Salvage window <6 hours

Do

  • NPO, prep for OR immediately
  • Doppler US → confirm ↓flow

Avoid

  • Do NOT delay for tests
Red flag to remember

Treat sudden severe testicular pain as torsion until proven otherwise and escalate immediately; every hour of delay risks losing the testicle.

What is testicular torsion?

It is a true urologic surgical emergency most common in adolescents and is time-critical: the testicle can usually be saved only if detorsion occurs within about 6 hours.

Key points to remember

  • Presents with sudden, severe, unilateral testicular pain, often with nausea/vomiting, scrotal swelling, and a high-riding testicle with absent cremasteric reflex.
  • It is a surgical emergency; testicular viability drops sharply after about 6 hours of ischemia.
  • Pain is NOT relieved by elevating the scrotum (negative Prehn sign), unlike epididymitis where elevation tends to help.
  • Diagnosis is clinical and confirmed by Doppler ultrasound showing decreased/absent blood flow; surgery should not be delayed for imaging if torsion is obvious.
  • Treatment is emergent surgical detorsion and orchiopexy, usually fixing both testes to prevent recurrence.
  • There is no fever or pyuria, which helps distinguish it from infectious causes.

Signs & symptoms

  • SUDDEN severe testicular pain
  • Swollen, high-riding testis
  • Absent cremasteric reflex, N/V

Nursing priorities

  1. Recognize torsion immediately and notify the surgeon/provider STAT to expedite the operating room.
  2. Keep the patient NPO and prepare for emergency surgery.
  3. Provide analgesia and antiemetics as ordered while preserving time-to-surgery.
  4. Do NOT delay definitive treatment; assist with rapid Doppler ultrasound only if it does not postpone surgery.
  5. Offer reassurance and reduce anxiety in the patient and family.

Labs & values

No characteristic lab changes; urinalysis typically NORMAL (no pyuria/bacteriuria, helping rule out infection)

Patient teaching

  • Any boy or man with sudden severe testicular pain must seek emergency care immediately, day or night.
  • After orchiopexy, both testicles are usually fixed to prevent recurrence.
  • Report severe scrotal pain, swelling, or recurrence right away.

Red flags: report now

  • Treat sudden severe testicular pain as torsion until proven otherwise and escalate immediately; every hour of delay risks losing the testicle.
  • Never apply heat, manually manipulate, or wait/observe; the window for salvage is about 6 hours.
  • Report a high-riding testicle with absent cremasteric reflex as a hallmark needing emergency surgery.
