🚨 TWIST Score (Testicular Torsion)

UseWhen to use: ED/clinic acute unilateral scrotal pain before or with Doppler.

Strata≤2 lower band (US often OK if timely); 3–4 intermediate; ≥5 high — urgent urology.

LimitsWhen not to use: as sole reason to delay surgery when suspicion is hi… · Pitfall: waiting for Doppler in high-risk phenotype. · Neonates/infants need lower threshold for exploration.

How it works

Swelling +2, hard testis +2, absent cremasteric +1, nausea/vomiting +1, high-riding +1 (0–7).

Key points

  • 0–7 score.
  • ≥5 high-risk cue.
  • Next: Doppler / urology.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
