Natural history of pelvic floor disorders before and after hysterectomy for gynaecological cancer
Abstract
Objective
To investigate the prevalence and severity of pelvic floor disorders (PFD), and the associations between treatment type and PFD, and cancer stage and PFD in patients before and after hysterectomy for gynaecological cancer; and the changes in outcomes over time.
Design
Longitudinal cohort study.
Setting
Gynaecological oncology outpatient clinics.
Population
Patients undergoing hysterectomy for endometrial, uterine, ovarian or cervical cancer.
Methods
Participants were assessed before, and 6 weeks and 3 months after hysterectomy. Changes over time were analysed using generalised estimating equations or linear mixed models. Associations were analysed using logistic regression models and analyses of variance.
Main outcome measures
Incontinence Severity Index, Pelvic Floor Distress Inventory‐short form (PFDI‐20), Female Sexual Function Index.
Results
Of 277 eligible patients, 126 participated. Prevalence rates of PFD were high before (urinary incontinence [UI] 66%, faecal incontinence [FI] 12%, sexual inactivity 73%) and after (UI 59%, FI 14%, sexual inactivity 58%) hysterectomy. Receiving adjuvant therapy led to moderate‐to‐very severe UI 3 months after surgery compared with surgery only (odds ratio 4.98, 95% CI 1.63–15.18). There was no association between treatment type and other PFD, or cancer stage and any PFD.
Conclusion
Prevalence of PFD was high before and after hysterectomy for gynaecological cancer. Moderate‐to‐very‐severe UI was associated with adjuvant therapy.
