Long-Term Experience with Modified McCall Culdoplasty in Women Undergoing Vaginal Hysterectomy for Pelvic Organ Prolapse

Objective: The incidence of post-hysterectomy vault prolapse following native tissue repair has been reported to be as high as 43%. The optimal way to maintain vault support is unknown. Our aim was to evaluate the long-term efficacy of modified McCall culdoplasty during vaginal hysterectomy for symptomatic uterine prolapse in preventing the recurrence of vaginal vault prolapse. Methods: We conducted a retrospective chart review involving 490 patients who underwent vaginal hysterectomy with modified McCall culdoplasty, with or without a concomitant stress incontinence procedure, between January 2008 and December 2018 at Mount Sinai Hospital in Toronto. Data analyzed included patient demographics, preoperative prolapse staging, intraoperative and postoperative complications, and postoperative subjective and objective success rates. Results: A total of 490 patients underwent vaginal hysterectomy with modified McCall culdoplasty. The mean follow-up period was 2.8 years. The objective success rate of vault support was 97.1%, and the subjective success rate was 94.1%. The total rate of reoperation for recurrence of vault prolapse was 1.0%. The objective cystocele recurrence rate was 8.6%, and 2.4% of these cases required reoperation. The objective rectocele recurrence rate was 4.7%, with 1.2% requiring reoperation. Unilateral ureteric kinking requiring intraoperative release of the McCall suture was recorded for 2.9% of patients. Overall, there was significant improvement in urinary, bowel, and prolapse symptoms post procedure. Conclusion: This cohort of patients who underwent modified McCall culdoplasty had low rates of vault prolapse recurrence and prolapse symptoms. The modified McCall culdoplasty technique practised at our institution is safe and effective in preventing post-hysterectomy vault prolapse.
