Detailed female cadaver dissections reveal inaccuracies in current anatomical descriptions of the urethra and surrounding erectile tissues. Researchers recommend renaming the bulbs of the vestibule to the bulbs of the clitoris for greater accuracy.

Area of Science:

  • Female pelvic anatomy
  • Urogenital system anatomy
  • Surgical anatomy

Background:

  • Current anatomical descriptions of the female urethra and surrounding erectile tissues may be inaccurate.
  • Existing nomenclature may not precisely reflect the anatomical relationships.

Purpose of the Study:

  • To investigate the anatomical relationship between the female urethra and surrounding erectile tissue.
  • To review the appropriateness of current nomenclature for this anatomy.

Main Methods:

  • Detailed dissection of 10 adult human female cadavers (2 fresh, 8 fixed).
  • Ascertained the relationship of the urethra to surrounding erectile tissue.
  • Noted nerve supply and relationship to pelvic structures.

Main Results:

  • The female urethra is embedded in the anterior vaginal wall, surrounded by erectile tissue except posteriorly.
  • The erectile tissue complex projects 3-6 cm from bony landmarks, contrary to common depictions.
  • The bulbs of the vestibule are inconsistently associated with the vestibule and are recommended to be renamed the bulbs of the clitoris.

Conclusions:

  • Current anatomical descriptions of female human urethral and genital anatomy are inaccurate.
  • The nomenclature for the bulbs of the vestibule requires revision to accurately reflect their anatomical connections.
