Summary

A gunshot injury damaged the S2 spinal nerve, causing isolated erectile dysfunction in a young man. Penile prosthesis implantation successfully treated his condition.

Area of Science:

  • Neuroscience
  • Urology
  • Trauma Surgery

Background:

  • Erectile dysfunction (ED) can result from various etiologies, including neurological damage.
  • Sacral nerve injuries, particularly to the S2 nerve root, can disrupt the autonomic and somatic pathways controlling penile function.
  • Isolated ED without bladder dysfunction suggests a specific neurological pathway injury.

Observation:

  • A 22-year-old male presented with isolated erectile dysfunction following a sacral gunshot injury.
  • The injury specifically targeted the right S2 spinal nerve.
  • The patient retained normal bladder innervation and function.

Findings:

  • The sacral gunshot injury led to damage of the right S2 spinal nerve, resulting in isolated erectile dysfunction.
  • Successful treatment was achieved through the implantation of a penile prosthesis.
  • Preservation of bladder function indicates the injury's localized impact on specific neural pathways.

Implications:

  • This case highlights the S2 spinal nerve's critical role in erectile function.
  • Penile prosthesis implantation is an effective treatment for neurogenic erectile dysfunction secondary to localized spinal nerve damage.
  • Understanding specific nerve involvement aids in targeted treatment strategies for sexual dysfunction post-trauma.
