Introduction and hypothesis
The aim of this study was to investigate the association between patient age at the time of hysterectomy and subsequent pelvic organ prolapse (POP) surgery.
Methods
We gathered data on all benign hysterectomies and POP surgeries performed in Denmark on Danish women from 1977 to 2009 from the Danish National Patient Registry. The cohort consisted of 154,882 hysterectomized women, who were followed up for up to 32 years. Survival analysis for each age group at hysterectomy was performed using Kaplan–Meier product limit methods.
Results
For all hysterectomized women, we found that low age at hysterectomy yielded a lower risk of subsequent POP surgery than did hysterectomy at an older age. This difference diminished after stratification by indication; all non-POP hysterectomies had a low cumulative incidence at 8–11 % at the end of the follow-up period. For all women hysterectomized, the predominant compartment for POP surgery was the posterior. Women hysterectomized when aged over 66 years had a higher proportion of POP surgery in the apical compartment than in the other age groups (p = 0.000).
Conclusion
Our findings indicate that age at hysterectomy only marginally influences the risk of subsequent POP surgery for women hysterectomized for indications other than POP. If POP is the indication for hysterectomy, the risk of undergoing subsequent POP surgery increases substantially.
