Pelvic autonomic neuromonitoring: present reality, future prospects

Area of Science:

• Urology
• Neurophysiology
• Surgical Innovation

Background:

• Current methods for assessing the autonomic nervous system (ANS) rely on indirect end-organ measurements, which lack operating room acceptance.
• Pelvic and lower spine surgeries risk damage to the pelvic autonomic nerve supply, impacting patient outcomes, particularly post-prostatectomy.
• While safer dissection techniques are emerging, reliable nerve identification and monitoring remain elusive.

Purpose of the Study:

• To review the current limitations in assessing pelvic autonomic nerve function during surgery.
• To explore the potential of neurophysiological techniques for real-time nerve identification and monitoring.
• To discuss the feasibility of implementing these novel approaches in the operating room.

Main Methods:

• Review of existing literature on autonomic nervous system assessment and pelvic nerve anatomy.
• Analysis of animal studies demonstrating the interconnectedness of autonomic and somatic structures.
• Discussion of the physiological principles underlying erectile tissue engorgement and autonomic function.

Main Results:

• Existing methods for ANS assessment are inadequate for intraoperative use.
• Animal data highlight the complex relationship between autonomic and somatic neural pathways.
• Understanding the biochemistry and electrophysiology of erectile tissue provides a basis for neurophysiological monitoring.

Conclusions:

• There is a critical need for direct nerve monitoring, not just identification, in pelvic surgery.
• Neurophysiological techniques hold promise for identifying and monitoring pelvic autonomic function.
• Further investigation and implementation of these techniques could significantly improve surgical safety and patient outcomes.
