Favorable Postoperative Outcomes After Transvaginal Mesh Surgery Using a Wide-Arm ORIHIME® Mesh

Introduction Transvaginal mesh surgery (TVM) is an effective treatment option for pelvic organ prolapse (POP). Although ORIHIME®, the only available mesh product, is thin, soft, and easy to handle, it has the disadvantages of sliding off or mildly adhering to the surrounding tissues. The current study compared the efficacy of using wide-arm ORIHIME (Kono Seisakusho, Japan, Tokyo), non-wide arm ORIHIME, Gynemesh PS (Johnson and Johnson, Japan, Tokyo), and Polyform (Boston Scientific Japan, Japan, Tokyo) meshes for TVM. Methods The study included 116 patients who underwent TVM (Prolift with Gynemesh PS (n = 14); Elevate with Polyform (n = 43); Uphold with non-wide-arm ORIHIME (n = 24); Uphold with wide-arm ORIHIME (n = 35)) at our hospital. Pre- and post-surgical changes in symptoms were measured using questionnaires and 60-minute pad weight testing and compared by mesh type and surgical methods used. Results The residual urine volume, 60-minute pad weight testing, international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), and international consultation on incontinence questionnaire-short form score (ICIQ-SF) significantly improved one year postoperatively in the TVM with the wide-arm ORIHIME group. Comparison of pre and one-year postoperative findings by mesh type and surgical methods used showed no significant differences in the 60-minute pad test, IPSS, Quality of Life (QOL), OABSS, and urinary incontinence in daily life scores, and improvement in residual urine volume, ICIQ-SF, and mesh exposure and POP recurrence rates in the TVM with the wide-arm ORIHIME group. Conclusion TVM with wide-arm ORIHIME had better postoperative outcomes compared to TVM with other mesh products.
