Obesity as an independent risk factor for poor long-term outcome after mid-urethral sling surgery.

INTRODUCTION: High body mass index (BMI) is a risk-factor for stress urinary incontinence (SUI). Mid-urethral sling (MUS) surgery is an effective treatment of SUI. The aim of this study was to investigate if there is an association between BMI at time of MUS-surgery and the long-term outcome at 10 years. MATERIAL AND METHODS: Women who went through MUS surgery in Sweden between 2006 and 2010 and had been registered in the Swedish National Quality Register of Gynecological Surgery were invited to participate in the 10-year follow-up. A questionnaire was sent out asking if they were currently suffering from SUI or not and their rated satisfaction, as well as current BMI. SUI at 10 years was correlated to BMI at the time of surgery. SUI at 1 year was assessed by the postoperative questionnaire sent out by the registry. The primary aim of the study was to investigate if there is an association between BMI at surgery and the long-term outcome, subjective SUI at 10 years after MUS surgery. Our secondary aims were to assess whether BMI at surgery is associated with subjective SUI at 1-year follow-up and satisfaction at 10-year follow-up. RESULTS: The subjective cure rate after 10 years was reported by 2108 out of 2157 women. Higher BMI at the time of surgery turned out to be a risk factor for SUI at long-term follow-up. Women with BMI <25 reported subjective SUI in 30%, those with BMI 25-<30 in 40%, those with BMI 30-<35 in 47% and those with BMI ≥35 in 59% (p < 0.001). Furthermore, subjective SUI at 1 year was reported higher by women with BMI ≥30, than among women with BMI <30 (33% vs. 20%, p < 0.001). Satisfaction at 10-year follow-up was 82% among women with BMI <30 versus 63% if BMI ≥30 (p < 0.001). CONCLUSIONS: We found that higher BMI at the time of MUS surgery is a risk factor for short- and long-term failure compared to normal BMI.

Retropubic slings are more efficient than transobturator at 10-year follow-up: a Swedish register-based study.

INTRODUCTION AND HYPOTHESIS: Long-term performance of mid-urethral slings (MUS) and potential differences between the retropubic and the transobturator technique for insertion are scarcely studied. This study aims to evaluate the efficacy and safety 10 years after surgery and compare the two main surgical techniques used. METHODS: Women who underwent surgery with a MUS between 2006 and 2010 were identified using the Swedish National Quality Register of Gynecological Surgery and were invited 10 years after the operation to answer questionnaires regarding urinary incontinence and its impact on quality-of-life parameters (UDI-6, IIQ-7) and impression of improvement, as well as questions regarding possible sling-related complications and reoperation. RESULTS: The subjective cure rate reported by 2421 participating women was 63.3%. Improvement was reported by 79.2% of the participants. Women in the retropubic group reported higher cure rates, lower urgency urinary incontinence rates and lower UDI-6 scores. No difference was shown between the two methods regarding complications, reoperation due to complications or IIQ-7 scores. Persisting sling-related symptoms were reported by 17.7% of the participants, most commonly urinary retention. Mesh exposure was reported by 2.0%, reoperation because of the tape by 5.6% and repeated operation for incontinence by 6.9%, significantly more in the transobturator group (9.1% vs. 5.6%). Preoperative urinary retention was a strong predictor for impaired efficacy and safety at 10 years. CONCLUSIONS: Mid-urethral slings demonstrate good results for the treatment of stress urinary incontinence and tolerable complication profiles in a 10-year perspective. The retropubic approach displays higher efficacy than the transobturator, with no difference regarding safety.

Perineorrhaphy Compared With Pelvic Floor Muscle Therapy in Women With Late Consequences of a Poorly Healed Second-Degree Perineal Tear: A Randomized Controlled Trial.

OBJECTIVE: To evaluate outcomes after pelvic floor muscle therapy, as compared with perineorrhaphy and distal posterior colporrhaphy, in the treatment of women with a poorly healed second-degree obstetric injury diagnosed at least 6 months postpartum. METHODS: We performed a single center, open-label, randomized controlled trial. After informed consent, patients with a poorly healed second-degree perineal tear at minimum 6 months postpartum were randomized to either surgery or physical therapy. The primary outcome was treatment success, as defined by Patient Global Impression of Improvement, at 6 months. Secondary outcomes included the Pelvic Floor Distress Inventory, the Pelvic Floor Impact Questionnaire, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, and the Hospital Anxiety and Depression Scale. Assuming a 60% treatment success in the surgery group and 20% in the physical therapy group, plus anticipating a 20% loss to follow-up, a total of 70 patients needed to be recruited. RESULTS: From October 2015 to June 2018, 70 of 109 eligible patients were randomized, half into surgery and half into tutored pelvic floor muscle therapy. The median age of the study group was 35 years, and the median duration postpartum at enrollment in the study was 10 months. There were three dropouts in the surgery group postrandomization. In an intention-to-treat analysis, with worst case imputation of missing outcomes, subjective global improvement was reported by 25 of 35 patients (71%) in the surgery group compared with 4 of 35 patients (11%) in the physical therapy group (treatment effect in percentage points 60% [95% CI 42-78%], odds ratio 19 [95% CI 5-69]). The surgery group was superior to physical therapy regarding all secondary endpoints. CONCLUSION: Surgical treatment is effective and superior to pelvic floor muscle training in relieving symptoms related to a poorly healed second-degree perineal tear in women presenting at least 6 months postpartum.

Associations Between Childbirth and Urinary Incontinence After Midurethral Sling Surgery.

OBJECTIVE: To assess whether subsequent childbirths affect the outcomes of midurethral sling surgery with regard to stress urinary incontinence (SUI). METHODS: In this population-based cohort study, we used the validated Swedish nationwide health care registers (the Patient Register and the Medical Birth Register) to identify women with a delivery after midurethral sling surgery (n=207, study group). From the same registers we then randomly identified a control group who had no deliveries after their midurethral sling procedure (n=521, control group). The women in the control group were matched to the women in the study group by age and year of surgery. The Urogenital Distress Inventory and the Incontinence Impact Questionnaire were sent out to the study population. Symptomatic SUI was defined as the primary outcome. Secondary outcomes included the total Urogenital Distress Inventory score, Urogenital Distress Inventory subscale scores, and Incontinence Impact Questionnaire scores. RESULTS: A total of 728 women were eligible for the study. The response rate was 74%; 163 in the study group (64 with vaginal delivery and 95 with cesarean delivery) and 374 women in the control group were included in the analysis. The rate of SUI (primary outcome) was 36 of 163 (22%) in the study group and 63 of 374 (17%) in the control group. In a multivariate regression analysis of the primary outcome, we found no significant difference between the groups (odds ratio [OR] 1.2, 95% CI 0.7-2.0). Vaginal childbirth after midurethral sling surgery did not increase the risk of SUI compared with cesarean delivery (22% vs 22%, OR 0.6, 95% CI 0.2-1.4). There were no significant differences in Urogenital Distress Inventory and Incontinence Impact Questionnaire scores between any of the groups. CONCLUSION: Childbirth after a midurethral sling procedure is not associated with an increased risk of patient-reported SUI, and continence status is not affected by the mode of a subsequent delivery.
