PELVIC ANATOMY GROUP
Supported by the John O. L. DeLancey Fund

The mission of the SGS Pelvic Anatomy Group (PAG) is to advance the field of gynecologic surgery through research and education on pelvic anatomy. The PAG consists of three working groups:
 

Nomenclature Group

The mission of the Nomenclature Group is to create a standardized list of preferred terminology for female pelvic anatomy to be used in medical communication by creating a “concordance map” for anatomical terms for the female pelvis. Their work has produced the multiple publications that have informed the creation of this website. The terminology used in this work is based on the publication Terminologia Anatomica, 2nd edition, which is an international consensus publication on anatomic terminology.

Nomenclature Group Publications:

Hill AJ, Balgobin S, Mishra K, Jeppson PC, Wheeler T, Mazloomdoost D, Anand M, Ninivaggio C, Hamner J, Bochenska K, Mama ST, Balk EM, Corton MM, DeLancey JO. “Recommended standardized anatomic terminology of the posterior female pelvis and vulva based on a structured medical literature review”.  Accepted Am J Obstet Gynecol 2021

Balgobin S, Jeppson PC, Wheeler T, Hill AJ, Mishra K, Mazloomdoost D, Dunivan G, Anand M, Mama S, Bochenska K, Lewicky-Gaupp C, Balk EM, Corton MM, DeLancey JO. “Standardized Terminology of the Female Pelvic Apical Structures Based on a Structured Medical Literature Review.” Am J Obstet Gynecol 2020 Mar;222(3):204-218 PMID 31805273 [ABOG Maintenance of Certification article 2020]

3D Imaging

The mission of the 3D Imaging Group is to cultivate and disseminate the skills necessary to understand, interpret, and study three-dimensional imaging of the pelvis in order to advance understanding and future treatment of dynamic, in vivo, pelvic anatomy. The work of the 3D Imaging Group is integral to this website.

3D Imaging Group Publications:
Hong CX, Sheyn DD, Sammarco AG, DeLancey JOL. Geometric analysis of the urethral-vaginal interface in women with and without stress urinary incontinence. Oral Presentation. Society of Gynecologic Surgeons Annual Meeting 2021, June 27-30

Sammarco AG, Sheyn DD, Krantz TE, Rodrigues AA, Olivera CI, Kobernik EK, Masteling M, DeLancey JOL. A novel measurement of pelvic floor cross sectional area in older and younger women with and without prolapse. Am J Obstet Gynecol. 2019. Nov;221(5):521.e1-521.e7. PMID: 31401263

Digital Library

The mission of the Digital Library Group is to disseminate knowledge of female pelvic anatomy, promote the use of standardized anatomic terminology, and to advance the field of gynecologic surgery by creating and maintaining the most anatomically accurate resource for female pelvic anatomy. Since 2018 the Digital Library Group has been systematically developing this website to serve as a resource for anatomy teaching and study. This surgeon-led site uses surgical, clinical, and cadaver dissection photos, videos, and images reviewed by expert anatomists and field leaders. This website also disseminates the work of the Nomenclature and 3D Imaging Groups. Only precise historical drawings are included, and we have purposefully excluded digital recreations and illustrations, as they are typically inaccurate or incomplete.
