A 40-year-old man was admitted to this institution complaining of pain and swelling in the right testicle
three days after recieving a blow to the scrotum while playing beseball. Color Doppler sonography showed a
rupture of tunica albuginea and arterial blood flow in the testis. A hematocele and an approximately 15-mm
tear of the tunica albuginea with protrusion of the seminiferous tissue were discovered on exploration. The
hematocele was excised and the tunica albuginea was repaired. Presence of blood flow in the testis suggested
that the testis could be saved. Recent wide-spread use of ultrasonographic examination has increased the
rate of correct diagnosis in cases of testicular trauma to about 70%. Choice between orchiectomy and conservatice management is difficult, however. Nonetheless, Color Dopier ultrasonography is far more useful
than B-mode ultrasonography alone in determining the appropriateness of conservative management.
