Fracture of the penis: role of ultrasonography in localizing the cavernosal tear.

Fracture of the penis is a rare surgical emergency. A case is presented where a 7.5 mHz ultrasonography probe was used to demonstrate the tear in the corpus cavernosum. Ultrasonography was able to identify the site and extent of the injury. Preoperative ultrasonography shows the best place for surgical incision and can be used to avoid negative surgical exploration.
