Introduction and hypothesis: Peritonisation of mesh during Abdominal sacrocolpopexy is generally advocated to prevent adhesions to the viscera; however, randomized clinical trials are lacking. In this study; we aimed to investigate whether the mesh peritonisation is clinically significant or not. Material method: Thirty-four patients who were operated for the reason of pelvic organ prolapse were included in the study. Patients were divided into two groups by retrospective scanning from the files and surgical reports. Group 1 patients consisted of those who underwent peritonisation and group 2 patients consisted of those who did not in abdominal sacrocolpopexy. Results: Operative time and the amount of blood lost were statistically less in the group 2. Postoperative pain and analgesic drug requirements were obviously higher in the group 1. Postoperative De novo dyspareunia and urinary urgency were higher in the group 1. There were no statistical differences between the groups in terms of other complications. Conclusion: We noticed that there was no difference between the patients who were peritonized and those who were not in terms of postoperative complications.
