Introduction and hypothesis: To prospectively evaluate the use of a particular polypropylene Y mesh for robotic sacrocolpopexy. Methods: This was a prospective study of 120 patients who underwent robotic sacrocolpopexy. We compared preoperative and 12-month postoperative objective and subjective assessments via the Pelvic Organ Prolapse Quantification (POP-Q), the Pelvic Floor Distress Inventory, Short Form 20 (PFDI-20); the Pelvic Floor Impact Questionnaire, Short Form 7 (PFIQ-7); and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire 12 (PISQ-12). Objective 'anatomical success' was defined as POP-Q stage 0 or 1 at all postoperative intervals. We further defined 'clinical cure' by simultaneously considering POP-Q points and subjective measures. To be considered a 'clinical cure,' a given patient had to have all POP-Q points ≤0, apical POP-Q point C ≤5, no reported pelvic organ prolapse symptoms on the PFDI-20, and no reoperation for prolapse at all postoperative intervals. Results: Of the 120 patients, 118 patients completed the 1-year follow-up. The objective 'anatomical success' rate was 89 % and the 'clinical cure' rate was 94 %. The PFDI-20 mean score improved from 100.4 at baseline to 21.0 at 12 months ( p < 0.0001); PFIQ-7 scores improved from 61.6 to 8.0 ( p < 0.0001); and PISQ-12 scores improved from 35.7 to 38.6 ( p < 0.0009). No mesh erosions or mesh-related complications occurred. Conclusion: The use of this ultra-lightweight Y mesh for sacrocolpopexy, eliminated the mesh-related complications in the first postoperative year, and provided significant improvement in subjective and objective outcomes.
