OBJECTIVE: To compare anatomic outcomes after native tissue vaginal vault suspension among women categorized by their preoperative and 6-week postoperative genital hiatus size.
METHODS: We performed a retrospective cohort study in women who underwent native tissue vaginal vault suspension between 2005 and 2015. We defined a wide genital hiatus as 4 cm or greater and a normal genital hiatus as less than 4 cm. We compared three groups: 1) women with a wide genital hiatus preoperatively and 6 weeks postoperatively (persistently wide group), 2) women with a wide genital hiatus preoperatively but normal genital hiatus 6 weeks postoperatively (improved group), and 3) women with a normal genital hiatus preoperatively and 6 weeks postoperatively (stably normal group). Our primary outcome was composite anatomic failure at medium term, defined as either recurrent prolapse beyond the hymen or retreatment for prolapse with surgery or a pessary. Data were analyzed with appropriate bivariate analysis and logistic regression.
RESULTS: Our study population consisted of 260 women, with 39 of 260 (15.0%) in the persistently wide group, 157 of 260 (60.4%) improved, and 64 of 260 (24.6%) stably normal. Composite anatomic failure was significantly more likely in the persistently wide cohort as compared with the other groups (persistently wide 51.3%, improved 16.6%, stably normal 6.3%, overall P<.01, significant for all pairwise comparisons). These results were consistent when examining the anterior, apical, and posterior compartments individually. In a logistic regression analysis, the persistently wide group was associated with a 4.4-fold increased odds of composite failure (adjusted odds ratio [OR] 4.41, 95% CI 1.99-9.76, P<.01) compared with the improved group and a 15.8-fold increased odds compared with the stably normal group (adjusted OR 15.79, 95% CI 4.66-53.57, P<.01).
CONCLUSION: Women with a preoperative genital hiatus 4 cm or greater that is not surgically normalized after native tissue vaginal vault suspension are at significantly increased odds of anatomic failure in all compartments.
