Area of Science:

  • Neurosurgery
  • Regenerative Medicine
  • Urology

Background:

  • Neurogenic bladder dysfunction often results from lower spinal cord lesions.
  • Current treatments may not fully restore micturition function.
  • Nerve transfer offers a potential strategy for reinnervation.

Purpose of the Study:

  • To introduce novel nerve transfer techniques for neurogenic bladder.
  • To enable motor-to-motor and sensory-to-sensory reinnervation.
  • To assess the feasibility of these reconstructive methods.

Main Methods:

  • Developed intradural ventral root transfer for motor reinnervation.
  • Developed extradural postganglionic spinal nerve transfer for sensory reinnervation.
  • Conducted experimental studies in rats to demonstrate feasibility.

Main Results:

  • Demonstrated the feasibility of both intradural and extradural nerve transfer techniques in a rat model.
  • Proposed a modified technique using nerve grafts to minimize surgical invasiveness.
  • The approach aims to restore useful micturition in patients with spinal cord injuries.

Conclusions:

  • Novel nerve transfer techniques show promise for treating neurogenic bladder.
  • The proposed methods offer potential for functional recovery of micturition.
  • Minimally invasive approaches may reduce surgical risks and improve patient outcomes.
