Novel Pelvic and Retroperitoneal Anatomical Model for OBGYN Resident Education

Purpose: To create an anatomically accurate benchtop, low-cost model to teach Obstetrics and Gynecology (OBGYN) residents pelvic and retroperitoneal anatomy.


Background: Medical simulation is a useful tool to help healthcare providers practice procedures and identify anatomy. Our goal was to create a low-cost, anatomically accurate pelvic model with anatomical structures pertinent to gynecologic surgery.


Methods: The custom pelvic anatomy model was developed as a clay moquette using anatomy textbooks for reference and included commonly encountered anatomical features during gynecologic surgery. Volumetric visualization of a pelvic CT was used to confirm anatomy. The final model was created using 3D design software and 3D printed without didactic color. The spaces, vessels, and nerves were tagged on the model for testing with residents. The model was used to teach and help visualize pelvic and retroperitoneal anatomy for OBGYN residents from PGY1 to PGY4. A survey was given to 13 OBGYN residents before and after anatomy didactic.


Results: All residents (n=13) from PGY1 to PGY4 had zero to limited procedural experience identifying retroperitoneal anatomy as a primary surgeon. Residents’ ability to identify pelvic anatomy on the model increased significantly post-lecture (p=< 0.001). Additionally, the resident’s confidence with retroperitoneal pelvic anatomy increased (p=0.005). Residents strongly agreed the model was accurate for intraperitoneal (mean 4.769/5) and retroperitoneal anatomy (mean 4.769/5) and strongly agreed practice with the model could improve technique (mean 4.7/5).


Discussions: The novel model shows promise in teaching residents to identify pelvic and retroperitoneal anatomy without the cues of didactic color.
