Comparison between Elevate Anterior/Apical system and Perigee system in pelvic organ prolapse surgery: clinical and sonographic outcomes
Abstract
Objective: The aim of this study was to assess the incidence of de novo stress urinary incontinence (SUI) and sonographic features of implanted transvaginal mesh in continent women treated with Elevate™ anterior/apical [single-incision mesh (SIM-A)] or Perigee™ [transvaginal mesh with sacrospinous fixation (TVM + SSF)] in extensive pelvic organ reconstruction surgery. Methods: This prospective observational study was done from May 2010 to January 2013. Patients were recruited from two tertiary centers, and the Elevate™ and Perigee™ systems were compared. Patients who had overt or occult SUI, previous prolapse or mesh insertion were excluded. Result: Fifty-seven patients in the SIM-A group and sixty-one in the TVM + SSF group were analysed. All completed a minimum of 1-year follow-up. Groups were demographically and statistically similar. There was a significantly high incidence of de novo SUI postoperatively in the SIM-A group. The objective and subjective cure rate of pelvic organ prolapse (POP) were comparable between groups, with incidence of mesh erosion in the SIM-A group and three in the TVM + SSF group. Sonographic evaluation showed significant increase in mesh length in the SIM-A group. Conclusion: Elevate™ a offered lower incidence of mesh erosion and comparable results on anatomical POP correction; however, incidence of de novo SUI was high. There is an apparent lengthening of implanted Elevate® mesh sonographically.
