Objective: To study the impact of premenopausal risk‐reducing salpingo‐oophorectomy (RRSO), compared with postmenopausal RRSO, on urinary incontinence (UI) ≥10 years later. Design: Cross‐sectional study, nested in a nationwide cohort. Setting: Multicentre in the Netherlands. Population: 750 women (68% BRCA1/2 pathogenic variant carriers) who underwent either premenopausal RRSO (≤45 years, n = 496) or postmenopausal RRSO (≥54 years, n = 254). All participants were ≥55 years at the time of the study. Methods: Urinary incontinence was assessed by the urinary distress inventory‐6 (UDI‐6); a score ≥33.3 indicated symptomatic UI. The incontinence impact questionnaire short form (IIQ‐SF) was used to assess the impact on women's health‐related quality of life (HR‐QoL). Differences between groups were analysed using regression analyses adjusting for current age and other confounders. Main outcome measures: Differences in UDI‐6 scores and IIQ‐SF scores between women with a premenopausal and a postmenopausal RRSO. Results: Women in the premenopausal RRSO group had slightly higher UDI‐6 scores compared with women in the postmenopausal RRSO group (P = 0.053), and their risk of symptomatic UI was non‐significantly increased (odds ratio [OR] 2.1, 95% confidence interval [95% CI] 0.93–4.78). A premenopausal RRSO was associated with a higher risk of stress UI (OR 3.5, 95% CI 1.2–10.0) but not with urge UI. The proportions of women with a significant impact of UI on HR‐QoL were similar in the premenopausal and postmenopausal RRSO groups (10.4% and 13.0%, respectively; P = 0.46). Conclusions: More than 15 years after premenopausal RRSO, there were no significant differences in overall symptomatic UI between women with a premenopausal and those with a postmenopausal RRSO.

Objective: To examine the effect of a premenopausal risk‐reducing salpingo‐oophorectomy (RRSO) in women at increased risk of ovarian cancer on objective and subjective cognition at least 10 years after RRSO. Design: A cross‐sectional study with prospective follow‐up, nested in a nationwide cohort. Setting: Multicentre in the Netherlands. Population or Sample: 641 women (66% BRCA1/2 pathogenic variant carriers) who underwent either a premenopausal RRSO ≤ age 45 (n = 436) or a postmenopausal RRSO ≥ age 54 (n = 205). All participants were older than 55 years at recruitment. Methods: Participants completed an online cognitive test battery and a questionnaire on subjective cognition. We used multivariable regression analyses, adjusting for age, education, breast cancer, hormone replacement therapy, cardiovascular risk factors and depression. Main Outcome Measures: The influence of RRSO on objective and subjective cognition of women with a premenopausal RRSO compared with women with a postmenopausal RRSO. Results: After adjustment, women with a premenopausal RRSO (mean time since RRSO 18.2 years) performed similarly on objective cognitive tests compared with women with a postmenopausal RRSO (mean time since RRSO 11.9 years). However, they more frequently reported problems with reasoning (odds ratio [OR] 1.8, 95% confidence interval [95% CI] 1.1–3.1) and multitasking (OR 1.9, 95% CI 1.1–3.4) than women with a postmenopausal RRSO. This difference between groups disappeared in an analysis restricted to women of comparable ages (60–70 years). Conclusions: Reassuringly, approximately 18 years after RRSO, we found no association between premenopausal RRSO and objective cognition. [ABSTRACT FROM AUTHOR]
