Penile trauma is uncommon, but can be serious due to its urinary and sexual complications. After reviewing the literature, the authors examined three types of trauma of particular interest because of the specificity of the lesions induced and their treatment. The circumstances of onset, the various lesions observed, the complementary investigations required, and the therapeutic modalities are studied for each type of trauma. Fractures of the corpora cavernosa are diagnosed clinically. When in doubt, cavernography is the examination of choice. Treatment must be surgical by suture of the defect of the albuginea. Strangulations can lead to ulceration of the skin and urethral fistula. The causes of strangulation are varied, including the very unusual case of strangulation by a hair in a young circumcised boy. Automutilations of the penis are rare, but, after psychiatric assessment, microsurgical reimplantation can be performed with good functional and aesthetic results.
