Abstract

Introduction and hypothesis: Native tissue vaginal repairs are associated with relatively high levels of recurrence. Systematic reviews have noted that preoperative pelvic floor muscle strength was associated with increased risk of recurrence in the short term. Methods: This is a retrospective review of patients who underwent a primary reconstructive surgery for anterior compartment vaginal prolapse between 2001 and 2015. Patients were divided into “absent,” “weak” and “good” preoperative PFM strength (aPFM, wPFM and gPFM, respectively) based on a modified Oxford scale. Failure rates were determined by a composite of subjective and objective anatomic outcomes. Subjects who underwent re-operations or procedures for recurrent prolapse of the anterior compartment were considered failures. A p value < 0.05 was considered statistically significant. Results: Two hundred ninety-nine patients were included. The aPFM (n = 36), wPFM (n = 115) and gPFM (n = 148) groups had similar descriptive statistics, except subjects in the aPFM and wPFM groups were significantly older than the gPFM group (p = 0.008). All groups underwent similar reconstructive surgeries. Average length of follow-up of 143.9 weeks (41 to 717 weeks) was similar among the three groups (p = 0.472). For the primary outcome of composite failure, aPFM had significantly more anterior vaginal wall recurrences than both the wPFM and gPFM groups, 13.89% vs. 3.48% and 4.05%, respectively (p = 0.033). Conclusions: Patients with preoperative absent pelvic floor muscle strength (nonfunctioning PFM) had a significantly higher anterior vaginal wall recurrence rate than those with weak or good pelvic floor muscle strength.
