Use of dental drill handpiece to remove steel nut causing penile strangulation: a case report and review of the literature

Penile strangulation is an uncommon urological emergency that requires prompt intervention to avoid potentially serious sequelae including loss of the distal penis secondary to ischemia and subsequent gangrene. We present a case report of a patient who presented to the hospital with penile strangulation injury of 10-hour duration secondary to the presence of a thick hexagonal steel nut. This case is presented in accordance with Consensus Surgical Case Report guidelines.

A 24-year-old Vietnamese man presented to the emergency room with urinary retention and decreased penile sensation following a 10-hour history of penile strangulation due to the presence of a thick hexagonal steel nut that he had placed around the shaft of the penis for the purpose of sexual enhancement during masturbation. The hexagonal nut was tightly entrapping the penile shaft, resulting in edema, congestion, and swelling of the distal 5 cm of the phallus. Given the thickness of the foreign body as well as the degree of penile swelling, we were unable to remove the hexagonal nut using traditional methods of alleviating penile strangulation injuries. Following consultation with a dental colleague, a dental diamond drill handpiece was utilized to cut the foreign body without injury to the underlying penile skin. Subsequent follow-up in clinic demonstrated no significant urinary or sexual sequalae from this episode.

We report a case of penile strangulation requiring novel instrumentation and collaboration for successful treatment.
