Incidence of pelvic floor repair after hysterectomy: A population-based cohort study

Objective: The objective of the study was to assess the incidence of and risk factors for pelvic floor repair (PFR) procedures after hysterectomy. Study design: Using the Rochester Epidemiology Project database, we tracked the incidence of PFRs through June 2006 among 8220 Olmsted County, MN, women who had a hysterectomy for benign indications between 1965 and 2002. Results: The cumulative incidence of PFR after hysterectomy was 5.1% by 30 years. This risk was not influenced by age at hysterectomy or calendar period. Future PFR was more frequently required in women who had prolapse, whether they underwent a hysterectomy alone (eg, vaginal [hazard ratio (HR) 4.3; 95% confidence interval (CI) 2.5 to 7.3], abdominal [HR 3.9; 95% CI 1.9 to 8.0]) or a hysterectomy and PFR (ie, vaginal [HR 1.9; 95% CI 1.3 to 2.7] or abdominal [HR 2.9; 95% CI 1.5 to 5.5]). Conclusion: Compared with women without prolapse, women who had a hysterectomy for prolapse were at increased risk for subsequent PFR.
