Predictors for Pelvic Organ Prolapse Recurrence After Sacrocolpopexy: A Matched Case-Control Study.

OBJECTIVE: This study aimed to identify risk factors for prolapse recurrence after sacrocolpopexy. METHODS: This was a retrospective chart review with cross-sectional follow-up survey of 709 patients who underwent sacrocolpopexy of any modality from 2004 to 2014. Cases were defined as those with a composite failure, defined as having subjective bulge symptoms, retreatment, or anatomic prolapse (>/=stage 2 prolapse on the Pelvic Organ Prolapse Quantification system). Controls were patients without composite failure. The cases and controls were matched by surgeon and by date of surgery in a 1:4 ratio. RESULTS: We identified 153 cases and matched them to 487 controls. The overall incidence of prolapse recurrence was 21.6% (95% confidence interval [CI], 18.2%-24.1%). Of the recurrence cases, 34 (22.2%) underwent surgical retreatment; the most common surgical retreatment was a posterior colporrhaphy (n = 16 [47.1%]). On multivariable logistic regression, a preoperative genital hiatus size >/=4 cm (adjusted odds ratio [adjOR], 1.95; 95% CI, 1.18-3.25) and concurrent anterior colporrhaphy (adjOR, 2.11; 95% CI, 1.06-4.18) were associated with increased odds of having a composite failure. Patients who had a concurrent posterior colporrhaphy had lower odds of experiencing a failure (adjOR, 0.62; 95% CI, 0.42-0.94). CONCLUSIONS: In this large retrospective chart review of women who underwent sacrocolpopexy with a cross-sectional survey follow-up time frame of nearly 7 years, patients with a preoperative genital hiatus of 4 cm or greater and need for concurrent anterior colporrhaphy at the time of their index surgery had higher odds of prolapse recurrence. Conversely, women who underwent a concurrent posterior colporrhaphy had lower odds of a recurrence.
