Anatomic study of prolapse surgery with nonanchored mesh and a vaginal support device

Am J Obstet Gynecol. 2010 Dec;203(6):590.e1-7. doi: 10.1016/j.ajog.2010.08.005. Epub 2010 Sep 22.


Objective: The purpose of this study was to evaluate the anatomic position and relations to neighboring neurovascular structures of polypropylene implants after vaginal repair with nonanchored mesh and a vaginal support device in a cadaver model.

Study design: We undertook anatomic dissection of 6 cadavers, with and without prolapse after surgery.

Results: All polypropylene implants were positioned in accordance with the prescribed surgical technique. This surgery reconstructed the entire anterior and posterior pelvic floor compartments without extension beyond the pelvic cavity. A safe distance between the implants and their neighboring neurovascular structures (obturator nerve and vessels, 2.8-3.3 cm; pudendal nerve and internal pudendal vessels, 1.8-2.2 cm; sacral plexus, 2-2.2 cm) was observed.

Conclusion: Anatomic cadaver dissection confirmed the accurate and safe placement of the polypropylene implants with the use of the prescribed surgical technique.
