Abstract
Introduction and hypothesis
This study aims to determine the risk of pelvic organ prolapse (POP) and stress urinary incontinence (SUI) surgery related to mode of hysterectomy focusing on vaginal hysterectomy.
Methods
We performed a nationwide cohort study. Women exposed to hysterectomy on benign indications (n = 118,601) were compared to women unexposed to hysterectomy (n = 579,200). The outcome was defined as first occurrence of POP or SUI surgery. Hazard ratios (HRs) were calculated with 95% confidence intervals (CIs) using Cox proportional-hazards models.
Results
The greatest risks of POP (HR 4.9, 95% CI 3.4–6.9) or SUI surgery (HR 6.3, 95% CI 4.4–9.1) were observed subsequent to vaginal hysterectomy for pelvic organ prolapse. Having a vaginal hysterectomy for other reasons also significantly increased the risks of POP and SUI surgery compared to other modes of hysterectomy.
Conclusions
Hysterectomy in general, in particular vaginal hysterectomy, was associated with an increased risk for subsequent POP and SUI surgery.
