PURPOSE: Our aim was to determine the accuracy of ultrasound (US) examination-based testicular torsion diagnosis in adult patients with acute scrotal pain.
METHODS: A comprehensive electronic search was performed using internet retrieval systems up to 5 August 2018 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The quality of eligible studies was assessed using Quality Assessment for Studies of Diagnostic Accuracy (QUADAS-2). The diagnostic value of ultrasound in patients with testicular torsion was evaluated using pooled estimates of sensitivity, specificity, likelihood ratio, and diagnostic odds ratio, as well as the summary receiver operating characteristics curve.
RESULTS: Twenty-six studies with 2116 patients were included in the study. Overall diagnostic sensitivity was 0.86 [95% confidence interval (CI) 0.79-0.91] and specificity was 0.95 (95% CI: 0.92-0.97). Subgroup analysis of prospective studies showed pooled sensitivity of ultrasound for testicular torsion was 0.94 (95% CI 0.83-0.98), and pooled specificity was 0.98 (95% CI 0.94-1.00). Recent studies after 2010 showed diagnostic sensitivity of 0.95 (95% CI 0.84-0.99) and specificity of 0.98 (95% CI 0.93-0.99).
CONCLUSIONS: This meta-analysis demonstrated that ultrasound represents an effective imaging modality for diagnosing testicular torsion in adult patients with acute scrotal pain.
