Introduction and hypothesis
The primary aim was to characterize stress urinary incontinence (SUI) symptom distress and impact after a midurethral sling (MUS) in women ≥70 compared to women <70 years of age.
Methods
A retrospective cohort study of women undergoing a primary MUS was conducted. The primary outcome was SUI symptoms defined as either “moderately” or “quite a bit” responses to ≥1 of the two SUI questions of the Pelvic Floor Distress Inventory-20 (PFDI-20). Urgency urinary incontinence (UUI) was defined as either moderately or quite a bit responses to the UUI question of the PFDI-20. The Pelvic Floor Impact Questionnaire (PFIQ-7), Patient Satisfaction Questionnaire (PSQ), and Patient Global Impression of Improvement (PGI-I) questionnaires were also administered.
Results
The mean age of patients ≥70 years (n = 160) was 75.4 ± 4.5 and <70 years (n = 536) was 56.2 ± 9.4. Multivariable analysis revealed no difference in SUI failure rates in older compared to younger cohorts, adjusted odds ratio (OR) 1.7, 95 % confidence interval (CI) 0.9–3.1. Women <70 demonstrated greater improvement in urinary incontinence (UI) symptom impact [−20.4 (33.0) vs −12.2 (30.7), p = 0.01] and women ≥70 had greater persistent UUI symptoms (31.5 vs 23.3 %, p = 0.04); there was no difference between cohorts in resolution of UUI (29.6 vs 34.2 %, p = 0.34). Younger women reported a greater impression of improvement compared to older women (67.7 vs 56.6 %, p = 0.01, respectively).
Conclusions
Older and younger women have similar SUI outcomes after MUS; however, older women have more persistent UUI and a worse impression of improvement of their urinary tract condition.
