Transvaginal Mesh Surgery using the Adjusted Size of ORIHIME® Mesh with Wide-arm Widths: Favorable Postoperative Outcomes Compared to Conventional Polypropylene Mesh

A BSTRACT Objectives: Pelvic organ prolapse (POP) is defined as the downward displacement of pelvic structures. Transvaginal mesh surgery (TVM) is a surgical approach that serves as a viable intervention for POP repair; nonetheless, its effectiveness may differ depending on the mesh type and design employed. This study aimed to examine the influence of mesh type on postoperative quality of life (QOL) related to POP and other postoperative outcomes. Materials and Methods: Preoperative and postoperative parameters, including the prolapse QOL (P-QOL) questionnaire score, were evaluated between two patient groups: patients treated with a wide-arm ORIHIME ® mesh of adjusted mesh size (AMS) were assigned to the ORIHIME ® AMS (+) group, and patients treated with a Prolift-type TVM using Gynemesh ® PS or an Elevate-type TVM using a Polyform™ mesh comprised the nonORIHIME ® group. Results: Almost all postoperative P-QOL component scores significantly decreased from preoperative scores in both groups. However, no significant decreases were found in the personal relationship subscale scores at 3 and 12 months postsurgery in the ORIHIME ® AMS (+) group and at 3 months postsurgery in the non-ORIHIME ® group compared with their preoperative values. The role limitations’ subscale was significantly lower in the ORIHIME ® AMS (+) group than in the non-ORIHIME ® group. The ORIHIME ® AMS (+) group demonstrated significantly better outcomes in urinary incontinence (UI) and mesh exposure rates compared with the non-ORIHIME ® group. Conclusion: Adjustment of the wide-arm ORIHIME ® mesh size improved postoperative QOL and reduced complications such as UI compared with TVM using conventional mesh products.
