Bilateral transection of the vas deferens: an unusual trauma from a cross stab injury of the scrotum.

An unusual case of division of both vas deferens in a patient with a cross stab injury to the root of scrotum is described. The management of this case in the emergency setting is discussed. The case illustrates the need to explore every case of penetrating trauma to the scrotum, even in the absence of active bleeding, to avoid missing such injuries. These injuries, although not life-threatening, can have a profound impact on the patient's future fertility and this may only manifest several years after the injury.
