外傷性陰茎転位症の1例

Abstract

We report a rare case of a traumatic dislocation of the penis. The patient was a 39-year-old man who was ambulanced to our hospital because of a motorbike accident. He was diagnosed to have a pelvic fracture. He was admitted to our department because of his urinary retention and lower abdominal pain. Only the penile skin was left as the genital organ, and neither the penis nor the glans penis was palpable. As the computed tomography scan of the abdomen revealed the dislocation of the penis under the skin in the foreside of the pubic bone, urinary retention due to the traumatic dislocation of the penis was diagnosed, and a percutaneous cystostomy was performed. After improvement of his general condition, the patient was transferred to our department for the evaluation of the perineal region, including the lower urinary tract, and for the treatment of the traumatic dislocation of the penis. First, as hematoma and abscess in the left spermatic cord were suspected by magnetic resonance imaging of the pelvic region, removal of the hematoma and abscess in the left spermatic cord as well as an anterograde cystoscopy were performed under lumbar anesthesia, and the absence of urethral injury was confirmed. After infection control, repositioning of the penis was jointly performed with the Department of Plastic Surgery of our hospital under general anesthesia. After the operation, spontaneous urination was observed and erectile function was observed to be normal.
