Point-of-care testicular ultrasound using doppler ultrasound imaging - Appropriate flow is demonstrated to the left testicle (#) indicated by color signal and arterial waveform on pulse wave doppler (arrow). No consistent color signal is appreciated over the right testicle (star), confirming the diagnosis of testicular torsion.

Point-of-care ultrasound (POCUS) was performed using a high-frequency linear probe, which was placed in the transverse axis along the scrotum to obtain an image where both testicles are visible side by side (Figure 1).
Doppler ultrasound imaging of right testicle during attempted detorsion. A) There was still absence of blood flow after initial detorsion attempt demonstrated by lack of color signal over the right testicle (star). B) After additional detorsion, color signal is now visible over the right testicle (X) and return of arterial waveform on pulse wave doppler (arrow), indicating restoration of blood flow.

Bedside ultrasound was used to reevaluate the testicle and it continued to demonstrate a lack of flow (Figure 2A). Bedside ultrasound confirmed return of blood flow to the testicle (Figure 2B).
