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

Abstract

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. We undertook anatomic dissection of 6 cadavers, with and without prolapse after surgery. 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. Anatomic cadaver dissection confirmed the accurate and safe placement of the polypropylene implants with the use of the prescribed surgical technique.
