Evaluating the TWIST score and point-of-care ultrasound for paediatric testicular torsion

Although the TWIST score and POCUS had high diagnostic accuracy for paediatric testicular torsion when performed by EPs or paediatricians in the ED, the non-negligible, false-negative rate indicated that the TWIST score should be used for risk stratification rather than as an exclusionary method.

Although the TWIST score and POCUS had high diagnostic accuracy for paediatric testicular torsion when performed by EPs or paediatricians in the ED, the non-negligible, false-negative rate indicated that the TWIST score should be used for risk stratification rather than as an exclusionary method.
