This systematic review and meta-analysis evaluated the diagnostic accuracy of ultrasound for testicular torsion in children and young people (CYP). Analyzing 6790 cases from 38 studies, the review found a pooled sensitivity of 0.93 and specificity of 0.99. However, it identified a 5.6% rate of missed torsion when flow was the sole diagnostic criterion.
Key findings
- Pooled sensitivity of ultrasound for testicular torsion was 0.93.
- Pooled specificity of ultrasound for testicular torsion was 0.99.
- 5.6% of testicular torsions were missed when flow was the only diagnostic criterion.
- Studies often had poor outcome definitions and short follow-up durations.
Why it matters
Understanding the diagnostic accuracy of ultrasound in pediatric populations is crucial, as misdiagnosis can lead to testicular loss. This review highlights the need for careful interpretation of ultrasound results in acute scrotal conditions.
What to keep in mind
Many studies included in the review had poor definitions of outcomes and short follow-up durations.
