Transvaginal round-infundibulopelvic ligament colposuspension after vaginal hysterectomy in high-grade uterovaginal prolapse: 11-year outcome

Abstract

ObjectiveTo interpret the long-term outcomes of transvaginal round-infundibulopelvic ligament colposuspension after vaginal hysterectomy in patients with stage 3–4 uterovaginal prolapse. Study designThis retrospective case–control study from 2007 to 2016 analysed patients’ medical records and evaluated gynaecological examinations over 11 years of follow-up. One hundred and forty-three patients who underwent transvaginal round-infundibulopelvic ligament colposuspension after vaginal hysterectomy were evaluated. The prespecified primary outcome evaluated at 11-year follow-up was apical prolapse of stage 2 or higher evaluated by the Pelvic Organ Prolapse Quantification System (POP-Q), in combination with bothersome bulge symptoms or repeat surgery for recurrent apical prolapse. The secondary outcome was overall anatomical failure (recurrent prolapse of stage 2 or higher in apical, anterior or posterior compartment). The rate of recurrence of apical prolapse was compared between groups using the McNemar test. ResultsThe mean (± standard deviation) follow-up period was 88.15 ± 2.519 months (95 % confidence interval 83.17–93.13). The pre-operative diagnoses were stage 3 uterovaginal prolapse in 23 (16.08 %) patients, stage 4 uterovaginal prolapse in 120 (83.91 %) patients, rectocele in 119 (83.21 %) patients, cystocele in 138 (96.50 %) patients and stress urinary incontinence in 53 (37.06 %) patients. Ten (8.33 %) patients with stage 4 uterovaginal prolapse developed postoperative apical prolapse, whereas none of the patients with stage 3 uterovaginal prolapse developed postoperative apical prolapse. Postoperatively, the POP-Q stages of apical prolapse were significantly lower compared with pre-operatively (p < 0.001). Postoperatively, the apical prolapse rate was 7.0 %, the recurrent cystocele rate was 2.07 %, the recurrent rectocele rate was 5.5 %, and the recurrent stress urinary incontinence rate was 18.87 %. Overall, postoperative anatomical failure occurred in 21 of 143 (14.68 %) women. One (0.69 %) patient developed perioperative bladder perforation, two (1.39 %) patients experienced voiding difficulty, and eight (5.59 %) patients experienced vaginal spotting. ConclusionTransvaginal round-infundibulopelvic ligament colposuspension during vaginal hysterectomy is an effective and useful method that reduces the rate of postoperative apical prolapse in patients with high-grade uterovaginal prolapse.
