Blunt scrotal trauma: emergency department evaluation and management.

Blunt scrotal trauma may result in a variety of injuries, including testicular rupture, torsion, dislocation, hematoma, or contusion, as well as epididymal, scrotal, and urethral injuries. Testicular rupture occurs in 50% of patients with traumatic hematocele, and is probably frequently misdiagnosed. If not aggressively diagnosed and surgically repaired, testicular rupture may lead to testicular atrophy and loss. Traumatic testicular torsion must also be diagnosed early to preclude testicular loss. Testicular scan, when rapidly available, is indicated in any case of suspected traumatic torsion. If testicular scanning is unavailable or equivocal, surgical exploration is indicated. Once torsion is ruled out, ultrasound is a useful diagnostic technique in acute scrotal trauma to differentiate those scrotal and testicular injuries requiring surgical intervention.
