Is transvaginal mesh surgery with polytetrafluoroethylene mesh ORIHIME® feasible for anterior pelvic organ prolapse?—Randomized comparative study between ORIHIME® and Polyform™

Transvaginal mesh surgery for pelvic organ prolapse has been widely performed in Japan, but polypropylene mesh has not been used in Japan since the ban on TVM using polypropylene mesh in the United States. Currently, polytetrafluoroethylene mesh ORIHIME® is the only mesh available for TVM in Japan. Although polytetrafluoroethylene is a safe material, its low coefficient of friction and insufficient adhesion to the surrounding tissue make it difficult to maintain the mesh position when it is used in the transvaginal mesh surgery. The aim of this study was to evaluate the feasibility of TVM-A2 using ORIHIME®.
