Objectives: The extraperitoneal uterosacral ligament suspension (ULS) can be performed during the removal of the uterus in vaginal hysterectomy to prevent cuff prolapse. In this study, we evaluated the modified extraperitoneal ULS technique in terms of preventing cuff prolapse. Methods/Technique: Forty patients with second and third-stage uterine prolapse who were operated were included in the study. During routine vaginal hysterectomy procedure performed on patients, after sacrouterine ligaments which are the first-bites and uteroovarian and round ligaments which are the last-bites have been sutured and knotted, these ligaments were marked with 4-distinct clamps to make the right and left, upper and lower separation. After vaginal cuff was closed the sutures hanged by the clamps were ligated together, and the cuff tissue was stretched to the apical line. Results: According to the POP-Q classification, 22 patients with stage-2 and 18 patients with stage-3 prolapse were operated. During the 2-year follow-up; 4 patients could not be reached and were excluded from follow-up. Five of the remaining 36 patients (13.8%) found to have stage-1 cuff prolapse and 31 (86.1%) of patients had no prolapse. There was no significant decrease in postoperative vaginal length (p $>$ 0.05). The PISQ-12 sexual function scores was found similar before and after surgery (p $>$ 0.05). Conclusions: The extraperitoneal ULS is a successful method to prevent cuff prolapse after hysterectomy. Although there are various modified forms of this method, the modified ULS, which we have described as the 4-clamp method, seems to be successful in terms of initial results.
