Summary

The bladder-anal reflex (BAR) was successfully evaluated in asymptomatic women, establishing normal latency and threshold ranges. This reflex is obtainable and aligns with the known anatomy of the lower urinary tract.

Area of Science:

  • Urology
  • Neuroscience
  • Pelvic Floor Function

Background:

  • Urinary incontinence, voiding dysfunction, and pelvic organ prolapse are prevalent in women.
  • Pelvic nerve function evaluation aids in assessing these conditions.
  • Existing reflex testing methods include urethral-anal and clitoral-anal reflexes.

Purpose of the Study:

  • To evaluate bladder-anal reflex (BAR) latency in asymptomatic women.
  • To determine the anatomical pathway of the BAR using selective anesthesia and neuromuscular block.
  • To establish reference ranges for BAR latency and threshold.

Main Methods:

  • Recruited 22 asymptomatic female subjects and 2 patients for BAR evaluation.
  • Utilized selective anesthesia and neuromuscular block to investigate reflex pathways.

  • Defined reference ranges based on mean values plus two standard deviations.

    • Main Results:

    • Established reference ranges for BAR latency (upper limit 91 msec) and threshold (upper limit 37.7 mA).
    • Identified latency values above 91 msec as potentially abnormal.
    • Noted that lower thresholds were not clinically significant in this cohort.

    Conclusions:

    • The bladder-anal reflex (BAR) is obtainable in asymptomatic women.
    • The BAR findings are consistent with the known anatomy and innervation of the lower urinary tract.
