[High-frequency color Doppler ultrasonography: valuable for diagnosis of polyorchidism].

OBJECTIVE

To investigate the application value of high-frequency color Doppler ultrasonography in the diagnosis of polyorchidism.

METHODS

We retrospectively studied 6 cases of polyorchidism diagnosed by ultrasound, 5 of which were pathologically confirmed, and analyzed the sonographic and clinical findings.

RESULTS

All the 6 cases were triorchidism, 4 located in the scrotum, and 2 in the same groin with indirect hernia. The supernumerary testis was linked to the epididymis in 3 cases, 1 accompanied with repeated epididymis and vas deferens, and 2 connected to no vas deferens and epididymis. Color Doppler ultrasonography revealed blood flow signals in 4 cases, but not in the other 2.

CONCLUSION

Polyorchidism has typical sonographic appearances, and high-frequency color Doppler ultrasonography plays an important role in its diagnosis.
