Should we add unilateral sacrospinous ligament fixation to vaginal hysterectomy in management of stage 3 and stage 4 pelvic organ prolapse?

OBJECTIVE To compare ''vaginal hysterectomy alone'' with ''vaginal hysterectomy with prophylactic unilateral sacrospinous ligament fixation'' in terms of intraoperative complications and 1-year anatomic outcomes and symptoms in patients aged over 50 years who presented with stage 3 or 4 pelvic organ prolapse (POP). MATERIALS AND METHODS Thirty-five patients underwent vaginal hysterectomy alone and 32 patients underwent vaginal hysterectomy with unilateral sacrospinous ligament fixation because of benign pathology between January 2012, and June 2014, were retrospectively analyzed in this study. The patients' demographic data and preoperative and intraoperative findings were obtained from the hospital records and noted. The patients were invited by phone to a follow-up visit to assess their 1-year anatomic outcomes and symptoms. RESULTS There was no significant demographic difference between the patients who underwent vaginal hysterectomy alone and those who had a vaginal hysterectomy with sacrospinous ligament fixation. Both length of operation and hospital stay were significantly longer in the patients who underwent vaginal hysterectomy with sacrospinous ligament fixation (p<0.001); intraoperative complications requiring blood transfusion were also significantly more frequent in these patients compared with the patients who underwent vaginal hysterectomy only (p=0.048). Recurrence of vaginal vault prolapse was significantly more frequent in the patients with vaginal hysterectomy alone compared with those who had both vaginal hysterectomy and sacrospinous ligament fixation (p=0.035). CONCLUSION Unilateral sacrospinous ligament fixation might be added to vaginal hysterectomy in patients with stage 3 or 4 POP who are predicted to have long survival times. However, further studies with a larger sample size are needed in this area of research.
