Condition: Testicular Torsion · Acute Scrotum · Scrotal Pain · Sponsor: University Hospital, Linkoeping
This prospective multicenter observational study aims to evaluate the diagnostic accuracy of the Testicular Workup for Ischemia and Suspected Torsion (TWIST) score in adult patients presenting with acute scrotal pain in Swedish Emergency Departments. The TWIST score is a clinical decision tool originally validated in pediatric populations to stratify patients into low, intermediate, and high risk for testicular torsion. The study will include men aged 18-40 years presenting with scrotal pain or symptoms suggestive of torsion. Patients with scrotal trauma, symptom duration over one week, previous testicular surgery, or inability to give informed consent in Swedish will be excluded. Participants' clinical findings will be recorded on a standardized form, and the TWIST score will be calculated. Management will follow standard clinical practice independently of the study. Primary outcome is the diagnostic accuracy of the TWIST score to rule out testicular torsion in low-risk patients (TWIST 0-2). Secondary outcomes include diagnosis of torsion within 30 days, time to surgery, patient-reported pain, number of Doppler ultrasounds performed, and the potential reduction in unnecessary imaging. The study will be conducted at multiple Swedish sites, including Linköping University Hospital, under oversight by the Swedish Ethical Review Authority (Etikprövningsmyndigheten, decision number 2025-07400-01). The results aim to inform clinical practice by providing a validated decision-sup…
