High Uterosacral Ligament Fixation Versus McCall's Culdoplasty for Vaginal Vault Suspension in Utero-Vaginal Prolapse Surgery

Introduction: There are high chances of post-hysterectomy vault prolapse (PHVP) if the vault is not well supported after vaginal hysterectomy in cases of pelvic organ prolapse (POP). High uterosacral ligament suspension (HUSLS) and McCall's culdoplasty are the well-recommended modalities to suspend the vault after vaginal hysterectomy. As both the procedures are accessible to non-urologic gynaecologists, the study was planned in cases of POP. Objective: The study was conducted to compare the anatomic and functional outcomes of patients undergoing vaginal HUSLS vs. McCall's culdoplasty at the time of vaginal hysterectomy. Materials and methods: This prospective interventional study was done in a tertiary care hospital. A total of 80 patients were included and divided into two groups of 40 patients each. In one group, patients underwent high uterosacral ligament suspension and in the second group, McCall's culdoplasty was done for vault suspension. All procedures were done by two trained surgeons. The effectiveness of both the procedures was assessed by preoperative and postoperative pelvic organ prolapse quantification (POP-Q) (up to two years). Patients were followed for two years to see for any postoperative problem/recurrence. Results: Vault suspension by HUSLS showed better results than McCall's culdoplasty, in terms of POP-Q point C, perineal body (PB), genital hiatus (GH) and total vaginal length (TVL) as compared to McCall's culdoplasty. Conclusion: The anatomical correction is much better with HUSLS, which suspends the vault in the normal vaginal axis. However, it takes longer compared to McCall's culdoplasty, so the procedure should be individualised and performed with several precautions.
