Outcome of Laparoscopic Versus Vaginal High Uterosacral Ligament Vault Suspension at the Time of Hysterectomy

Introduction and HypothesisHigh uterosacral ligament suspension (HUSLS) can be used to treat apical pelvic organ prolapse (POP). This can be performed both vaginally and laparoscopically. Data comparing the two suspension procedures remain limited. The aim of this study is to compare the effectiveness and safety of vaginal HUSLS and laparoscopic HUSLS at the time of hysterectomy.MethodsThis is a retrospective cohort study of women who underwent hysterectomy between 2019 and 2021 at a tertiary urogynaecology unit. Either vaginal or laparoscopic hysterectomy was performed, followed by vaginal or laparoscopic HUSLS respectively. Women were followed up at 6 weeks, and at 6 and 12 months postoperatively. The primary outcome was symptomatic recurrence of vaginal bulge symptoms. Secondary outcomes were anatomical recurrence, re-treatment and safety.ResultsA total of 111 women met the inclusion criteria. Twelve were excluded, leaving 99 for analysis. HUSLS was performed vaginally in 47 and laparoscopically in 52 women. There was no significant difference in demographics between the groups. At 12 months, 92% in the vaginal group and 48% of the laparoscopic group reported no symptoms of prolapse, 67% vs 36% had no anatomical recurrence and 0% vs 34% had re-treatment respectively. Logistic regression (adjusting for age, BMI, menopausal status, preoperative stage apical prolapse, procedure type) demonstrated that the laparoscopic route was the only variable associated with recurrent prolapse at or beyond the hymen and symptomatic prolapse at 12 months.ConclusionsSymptomatic and anatomical recurrent POP was associated with this technique of laparoscopic HUSLS. Further research should consider prospective evaluation of these or modified techniques.
