Quality of life and sexual function after tension-free vaginal tape and polyacrylamide hydrogel injection for primary stress urinary incontinence: 3-year follow-up from a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: To assess quality of life (QoL) and sexual function outcomes at 3 years after tension-free vaginal tape (TVT) and polyacrylamide hydrogel injection (PAHG) for stress urinary incontinence (SUI). METHODS: In this randomized trial comparing TVT (n = 104) and PAHG (n = 108), we assessed changes in QoL and sexuality using the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire, Short Form (IIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and RAND-36 Item Health Survey (RAND-36) at baseline and at 3 years. This is a secondary analysis of a randomized, noninferiority trial comparing patient satisfaction after TVT and PAHG. RESULTS: In both groups, incontinence-related QoL improved from the baseline (p < 0.00), except for difficulty emptying the bladder and pain/discomfort. Total scores of UDI-6 and IIIQ-7 were lower for TVT compared to PAHG (p < 0.00) indicating better QoL at 3 years. Urinary incontinence with sexual activity or fear of incontinence restricting sexual activity improved in both groups (p < 0.00), with higher scores for physical section subscale in PISQ-12 (p = 0.02) for TVT. Physical and social functioning (RAND-36) improved from the baseline in both groups (p < 0.01) with a better outcome in the TVT group for physical functioning (p = 0.00). CONCLUSIONS: Both TVT and PAHG improve QoL and sexual function in primary SUI with better incontinence and health-related QoL scores in the TVT group compared to the PAHG group at 3 years.

Tension-Free Vaginal Tape and Polyacrylamide Hydrogel Injection for Primary Stress Urinary Incontinence: 3-Year Followup from a Randomized Clinical Trial.

PURPOSE: We sought to determine whether polyacrylamide hydrogel (PAHG) is noninferior to tension-free vaginal tape (TVT) in the treatment of women with primary stress urinary incontinence (SUI). MATERIALS AND METHODS: In this noninferiority trial, 223 women eligible for operative SUI treatment were randomized for TVT (110) or PAHG (113). Primary outcome was patient satisfaction and the noninferiority margin for the difference was 20%. Secondary outcomes were effectiveness and complications. RESULTS: At 3 years, 188 (84.3%) women attended the followup. The satisfaction score (visual analogue scale 0-100) median was 98.5 (IQR 90-100) in the TVT group and 90.0 (IQR 70-100) in the PAHG group, whereas a score ≥80 was reached in 87 (94.6%) and 65 (67.7%), respectively (difference 26.9%, 95% CI 16.7% to 36.8%). Thus, PAHG did not meet the noninferiority criteria set in our study. The cough stress test was negative in 88 (95.7%) of TVT patients vs 75 (78.1%) of PAHG patients (difference 17.5%, 95% CI 8.6% to 26.9%). Any peri- or postoperative complication before crossover between the groups was detected in 40 (43.5%) women in the TVT group and 23 (24.0%) women in the PAHG group (difference 19.5%, 95% CI 6.8% to 31.4%). CONCLUSIONS: In midterm followup, PAHG did not reach in patient satisfaction the noninferiority set in our study. Furthermore, mid urethral TVT slings show better subjective and objective cure rates than PAHG. However, complications were more often associated with TVT. Since the majority of PAHG treated women were also cured or improved, primary SUI women can be offered PAHG as a safe and durable alternative treatment.

Quality of life and sexual function after TVT surgery versus Bulkamid injection for primary stress urinary incontinence: 1 year results from a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: To assess changes in quality of life (QoL) and sexual function outcomes at 1 year after tension-free vaginal tape (TVT) versus polyacrylamide hydrogel injection (PAHG). METHODS: In a randomized trial comparing TVT (n = 111) and PAHG (n = 113) treatments of stress urinary incontinence (SUI), we compared urinary incontinence and health-related QoL using the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire, Short Form (IIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and RAND-36 Item Health Survey (RAND-36) at baseline and 1 year. RESULTS: UDI-6 and IIQ-7 showed improved incontinence-related QoL (p = 0.001) from baseline in both groups except for difficulty emptying the bladder and pain/discomfort. At 1 year, TVT patients experienced less urinary symptom-related distress compared to PAHG (p < 0.001). Sexual function improved in both groups (p < 0.001 for TVT and p = 0.01 for PAHG) with higher scores for the physical section subscale (p < 0.001) for TVT. Health-related QoL (RAND-36) improved from baseline in both groups in physical and social functioning (p < 0.001) with better outcome in the TVT group for physical functioning (p < 0.001). Increase in pain from baseline (p = 0.02) was detected for TVT, but not for PAHG. However, there was no difference between the groups (p = 0.78). CONCLUSIONS: In primary SUI, TVT and PAHG treatments both improved QoL and sexual function at 1 year. However, incontinence and health-related QoL scores were better in the TVT group. More pain compared to the baseline was reported after TVT, although there was no difference between groups. Clinical significance needs to be evaluated in long-term follow-up.

Tension-Free Vaginal Tape Surgery versus Polyacrylamide Hydrogel Injection for Primary Stress Urinary Incontinence: A Randomized Clinical Trial.

PURPOSE: We evaluated whether polyacrylamide hydrogel is noninferior to tension-free vaginal tape to treat women with primary stress urinary incontinence. MATERIALS AND METHODS: In this controlled noninferiority clinical trial patients with primary stress urinary incontinence were randomized to tension-free vaginal tape or polyacrylamide hydrogel treatment. The primary outcome was patient satisfaction and secondary outcomes were effectiveness in reducing urinary leakage and complications at 1-year followup. For statistical power significance was considered at 5%, power was set at 80% and the noninferiority limit was 20% with a 10% expected dropout rate. RESULTS: A total of 224 women with primary stress urinary incontinence entered the study between September 28, 2015 and March 1, 2017. Of the women 111 were randomized to tension-free vaginal tape and 113 were randomized to polyacrylamide hydrogel. At 1 year a satisfaction score of 80 or greater on a visual analogue scale of 0 to 100 was reached in 95.0% and 59.8% of patients treated with tension-free vaginal tape and polyacrylamide hydrogel, respectively. Thus, polyacrylamide hydrogel did not meet the noninferiority criteria set in our study. As secondary outcomes, the cough stress test was negative in 95.0% of tension-free vaginal tape cases vs 66.4% of polyacrylamide hydrogel cases (difference 28.6%, 95% CI 18.4-38.5). However, most perioperative complications, including those in 19 tension-free vaginal tape cases vs 3 polyacrylamide hydrogel cases (difference 16.0%, 95% CI 7.8-24.9), and all 6 reoperations due to complications (difference 5.9%, 95% CI 1.2-12.4) were associated with tension-free vaginal tape. CONCLUSIONS: Mid urethral tension-free vaginal tape slings were associated with better satisfaction and cure rates than polyacrylamide hydrogel in women with primary stress urinary incontinence. However, complications were mainly associated with tension-free vaginal tape. Thus, tension-free vaginal tape should be offered as first line treatment in women who expect to be completely cured by the initial treatment and are willing to accept the complication risks. Since polyacrylamide hydrogel treatment also provides high satisfaction and cure rates, women with primary stress urinary incontinence can be offered polyacrylamide hydrogel as an alternative treatment.
