Ultrasonography for the Diagnosis and Staging of Blunt Scrotal Trauma

Abstract

Of 19 patients with blunt testicular trauma diagnosed and staged correctly by physical examination and ultrasonography 10 were explored surgically and 9 were managed nonoperatively (treatment was supported by ultrasonography). Fractured testicles occurred in 5 of the 10 explored patients and were repaired surgically, and in 2 of the 9 conservatively managed patients. These 2 patients refused an operation. Ultrasonography can show disruption of the testicle as evidenced by intratesticular lucencies representing hematoma, extruded testicular parenchyma or a fragmented testicle. The tunica albuginea is too thin to be defined consistently and, thus, it could not be used as a parameter for disruption in the 10 patients who were explored surgically. Ultrasonography used in conjunction with a thorough physical examination is highly accurate, readily available, noninvasive and gives minimal discomfort. This modality can be used to follow nonoperative scrotal injury to resolution. With the availability of high resolution real-time ultrasonography more rapid and reliable screening of the scrotum is possible.
