Sonograhic Evaluation of Scrotal and Penile Trauma

Although physical examination is adequate in evaluating superficial injuries of scrotal and penile trauma, imaging is frequently performed to assess the vascular integrity and severity of injury. Ultrasound plays a significant role in evaluating the morphologic changes to the testis and penis. Color flow Doppler assesses the organ blood perfusion and localizes the vascular disruption, if any. The commonest scrotal injury is sports related, followed by motor vehicle accidents. Scrotal trauma can result in testicular rupture, fracture, dislocation, torsion, and hematocele. The major cause of penile injury is sex-related activity that results in penile fracture. This article discusses the role of sonography in scrotal and penile trauma and emphasizes the role of color and power Doppler and gray-scale imaging.
