Project description:ImportanceWomen with refractory urgency urinary incontinence are treated with sacral neuromodulation and onabotulinumtoxinA with limited comparative information.ObjectiveTo assess whether onabotulinumtoxinA is superior to sacral neuromodulation in controlling refractory episodes of urgency urinary incontinence.Design, setting, and participantsMulticenter open-label randomized trial (February 2012-January 2015) at 9 US medical centers involving 381 women with refractory urgency urinary incontinence.InterventionsCystoscopic intradetrusor injection of 200 U of onabotulinumtoxinA (n = 192) or sacral neuromodulation (n = 189).Main outcomes and measuresPrimary outcome, change from baseline mean number of daily urgency urinary incontinence episodes over 6 months, was measured with monthly 3-day diaries. Secondary outcomes included change from baseline in urinary symptom scores in the Overactive Bladder Questionnaire Short Form (SF); range, 0-100, higher scores indicating worse symptoms; Overactive Bladder Satisfaction questionnaire; range, 0-100; includes 5 subscales, higher scores indicating better satisfaction; and adverse events.ResultsOf the 364 women (mean [SD] age, 63.0 [11.6] years) in the intention-to-treat population, 190 women in the onabotulinumtoxinA group had a greater reduction in 6-month mean number of episodes of urgency incontinence per day than did the 174 in the sacral neuromodulation group (-3.9 vs -3.3 episodes per day; mean difference, 0.63; 95% CI, 0.13 to 1.14; P = .01). Participants treated with onabotulinumtoxinA showed greater improvement in the Overactive Bladder Questionnaire SF for symptom bother (-46.7 vs -38.6; mean difference, 8.1; 95% CI, 3.0 to 13.3; P = .002); treatment satisfaction (67.7 vs 59.8; mean difference, 7.8; 95% CI, 1.6 to 14.1; P = .01) and treatment endorsement (78.1 vs 67.6; mean difference; 10.4, 95% CI, 4.3 to 16.5; P < .001) than treatment with sacral neuromodulation. There were no differences in convenience (67.6 vs 70.2; mean difference, -2.5; 95% CI, -8.1 to 3.0; P = .36), adverse effects (88.4 vs 85.1; mean difference, 3.3; 95% CI, -1.9 to 8.5; P = .22), and treatment preference (92.% vs 89%; risk difference, -3%; 95% CI, -16% to 10%; P = .49). Urinary tract infections were more frequent in the onabotulinumtoxinA group (35% vs 11%; risk difference, -23%; 95% CI, -33% to -13%; P < .001). The need for self-catheterization was 8% and 2% at 1 and 6 months in the onabotulinumtoxinA group. Neuromodulation device revisions and removals occurred in 3%.Conclusions and relevanceAmong women with refractory urgency urinary incontinence, treatment with onabotulinumtoxinA compared with sacral neuromodulation resulted in a small daily improvement in episodes that although statistically significant is of uncertain clinical importance. In addition, it resulted in a higher risk of urinary tract infections and need for transient self-catheterizations.
Project description:BACKGROUND:Women with refractory urgency urinary incontinence can be treated with onabotulinumtoxinA or sacral neuromodulation. Little data exists on the comparative effects of treatment of refractory urgency urinary incontinence on other pelvic floor complaints, such as bowel and sexual function. OBJECTIVE:The objective of this study was to compare the impact of these treatments on fecal incontinence and sexual symptoms. METHODS:This was a planned supplemental analysis of a randomized trial in women with refractory urgency urinary incontinence treated with onabotulinumtoxinA (n = 190) or sacral neuromodulation (n = 174). Fecal incontinence and sexual symptoms were assessed at baseline and at 6, 12, and 24 months. Fecal incontinence symptoms were measured using the St Mark's (Vaizey) Fecal Incontinence severity scale. Sexual symptoms were measured using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) and the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR). The PISQ-IR allows measurement of sexual symptoms in both sexually active and non-sexually active adults. Primary outcomes were change in Vaizey and PISQ-12 scores between baseline and 6 months. Secondary outcomes were change in PISQ-IR total and subscores between baseline and 6 months and change in Vaizey, PISQ-12, and PISQ-IR scores between baseline and 12 and 24 months. Intent-to-treat analysis was performed using repeated measures mixed model to estimate change in all parameters from baseline while adjusting for the baseline score. A subgroup analysis of women with clinically significant bowel symptoms was conducted based on baseline Vaizey score of ?12. RESULTS:At baseline, mean Vaizey scores were indicative of mild fecal incontinence symptoms and were not different between onabotulinumtoxinA and sacral neuromodulation groups (7.6 ± 5.3 vs 6.6 ± 4.9, P = .07). The proportion of sexually active women (56% vs 63%, P = .25), mean PISQ-12 score (33.4 ± 7.5 vs 32.7 ± 6.7, P = .55), or PISQ-IR subscores were also not different between the onabotulinumtoxinA and sacral neuromodulation groups at baseline. There was no difference between women treated with onabotulinumtoxinA and those treated with sacral neuromodulation at 6 months in terms of improvement in fecal incontinence symptom score (Vaizey: -1.9, 95% confidence interval -2.6 to -1.2 vs -0.9, 95% confidence interval -1.7 to -0.2, P = .07) or sexual symptoms score (PISQ-12: 2.2, 95% confidence interval 0.7 to 3.7 vs 2.2, 95% confidence interval 0.7 to 3.7, P = .99). There was no difference in improvement between groups in the sexual symptom subscores in sexually active and non-sexually active women at 6 months. Similar findings were noted at 12 and 24 months. In a subgroup (onabotulinumtoxinA = 33 and sacral neuromodulation = 22) with clinically significant fecal incontinence at baseline (Vaizey score ?12), there was a clinically meaningful improvement in symptoms in both groups from baseline to 6 months, with no difference in improvement between the onabotulinumtoxinA and sacral neuromodulation groups (-5.1, 95% confidence interval -7.3 to -2.8 vs -5.6, 95% confidence interval -8.5 to -2.6, P = .8). CONCLUSION:There were no differences in improvement of fecal incontinence and sexual symptoms in women with urgency urinary incontinence treated with onabotulinumtoxinA or sacral neuromodulation. Women with significant fecal incontinence symptoms at baseline had clinically important improvement in symptoms, with no difference between the treatments. Our findings can help clinicians counseling women considering treatment for refractory urgency urinary incontinence.
Project description:PURPOSE:We measured urinary biomarker levels in women with refractory urgency urinary incontinence and controls at baseline and 6 months after treatment with sacral neuromodulation or intradetrusor injection of onabotulinumtoxinA. We also assessed the association of baseline biomarkers with posttreatment urgency urinary incontinence episodes and overactive bladder symptom bother outcomes. MATERIALS AND METHODS:First morning urine samples were collected from consented trial participants and age matched women without urgency urinary incontinence. Biomarkers reflecting general inflammation, neuroinflammation, afferent neurotransmitters and tissue remodeling were measured using standardized enzyme-linked immunosorbent assay and activity assays as appropriate. Symptom bother was assessed by the overactive bladder questionnaire and urgency urinary incontinence episodes were determined by bladder diary. Linear models were used to examine differences in mean biomarker levels and the change in urgency urinary incontinence episodes and symptom bother between baseline and 6 months. Modest evidence of a potential association was represented by p ?0.01 and p ?0.004 represented moderate evidence of an association with outcomes. RESULTS:Baseline biomarker levels differed little between cases and controls except tropoelastin (p = 0.001) and N-terminal telopeptide collagen type 1 (p <0.001). Changes in biomarker levels 6 months after intervention included decreases in collagenase (p <0.001) in both treatment groups and increases in interleukin-8 (p = 0.002) and matrix metalloprotease-9 (p <0.001) in the onabotulinumtoxinA group. Higher baseline calcitonin gene-related peptide across both treatments (p = 0.007) and nerve growth factor in the onabotulinumtoxinA arm (p = 0.007) were associated with less reduction in overactive bladder symptom bother. CONCLUSIONS:Refractory urgency urinary incontinence is a complex condition. These data suggest that matrix remodeling and neuropeptide mediation may be involved in its pathophysiological mechanisms and response to treatment.
Project description:PURPOSE:Sacral neuromodulation and intradetrusor onabotulinumtoxinA injection are therapies for refractory urgency urinary incontinence. Sacral neuromodulation involves surgical implantation of a device that can last 4 to 6 years while onabotulinumtoxinA therapy involves serial office injections. We assessed the cost-effectiveness of 2-stage implantation sacral neuromodulation vs 200 units onabotulinumtoxinA for the treatment of urgency urinary incontinence. MATERIALS AND METHODS:Prospective economic evaluation was performed concurrent with the ROSETTA (Refractory Overactive Bladder: Sacral NEuromodulation vs. BoTulinum Toxin Assessment) randomized trial of 386 women with 6 or more urgency urinary incontinence episodes on a 3-day diary. Analysis is from the health care system perspective with primary within-trial analysis for 2 years and secondary 5-year decision analysis. Costs are in 2018 U.S. dollars. Effectiveness was measured in quality adjusted life-years (QALYs) and reductions in urgency urinary incontinence episodes per day. We generated incremental cost-effectiveness ratios and cost-effectiveness acceptability curves. RESULTS:Two-year costs were higher for sacral neuromodulation than for onabotulinumtoxinA ($35,680 [95% CI 33,920-37,440] vs $7,460 [95% CI 5,780-9,150], p <0.01), persisting through 5 years ($36,550 [95% CI 34,787-38,309] vs $12,020 [95% CI 10,330-13,700], p <0.01). At 2 years there were no differences in mean reduction in urgency urinary incontinence episodes per day (-3.00 [95% CI -3.38 - -2.62] vs -3.12 [95% CI -3.48 - -2.76], p=0.66) or QALYs (1.39 [95% CI 1.34-1.44] vs 1.41 [95% CI 1.36-1.45], p=0.60). The probability that sacral neuromodulation is cost-effective relative to onabotulinumtoxinA is less than 0.025 for all willingness to pay values below $580,000 per QALY at 2 years and $204,000 per QALY at 5 years. CONCLUSIONS:Although both treatments were effective, the high cost of sacral neuromodulation is not good value for treating urgency urinary incontinence compared to 200 units onabotulinumtoxinA.
Project description:PURPOSE:We sought to identify clinical and demographic characteristics associated with treatment response and satisfaction in women undergoing onabotulinumtoxinA and sacral neuromodulation therapies. MATERIALS AND METHODS:We analyzed data from the ROSETTA (Refractory Overactive Bladder: Sacral NEuromodulation versus BoTulinum Toxin Assessment) trial. Baseline participant characteristics and clinical variables were associated with 2 definitions of treatment response, including 1) a reduction in mean daily urgency incontinence episodes during 6 months and 2) a 50% or greater decrease in urgency incontinence episodes across 6 months. The OAB-S (Overactive Bladder-Satisfaction) questionnaire was used to assess satisfaction. RESULTS:A greater reduction in mean daily urgency incontinence episodes was associated with higher HUI-3 (Health Utility Index-3) scores in the onabotulinumtoxinA group and higher baseline incontinence episodes (each p <0.001) in the 2 groups. Increased age was associated with a lesser decrease in incontinence episodes in the 2 groups (p <0.001). Increasing body mass index (adjusted OR 0.82/5 points, 95% CI 0.70-0.96) was associated with reduced achievement of a 50% or greater decrease in incontinence episodes after each treatment. Greater age (adjusted OR 0.44/10 years, 95% CI 0.30-0.65) and a higher functional comorbidity index (adjusted OR 0.84/1 point, 95% CI 0.71-0.99) were associated with reduced achievement of a 50% or greater decrease in urgency incontinence episodes in the onabotulinumtoxinA group only (p <0.001 and 0.041, respectively). In the onabotulinumtoxinA group increased satisfaction was noted with higher HUI-3 score (p = 0.002) but there was less satisfaction with higher age (p = 0.001). CONCLUSIONS:Older women with multiple comorbidities, and decreased functional and health related quality of life had decreased treatment response and satisfaction with onabotulinumtoxinA compared to sacral neuromodulation for refractory urgency incontinence.
Project description:BackgroundAnticholinergic medications and onabotulinumtoxinA are used to treat urgency urinary incontinence, but data directly comparing the two types of therapy are needed.MethodsWe performed a double-blind, double-placebo-controlled, randomized trial involving women with idiopathic urgency urinary incontinence who had five or more episodes of urgency urinary incontinence per 3-day period, as recorded in a diary. For a 6-month period, participants were randomly assigned to daily oral anticholinergic medication (solifenacin, 5 mg initially, with possible escalation to 10 mg and, if necessary, subsequent switch to trospium XR, 60 mg) plus one intradetrusor injection of saline or one intradetrusor injection of 100 U of onabotulinumtoxinA plus daily oral placebo. The primary outcome was the reduction from baseline in mean episodes of urgency urinary incontinence per day over the 6-month period, as recorded in 3-day diaries submitted monthly. Secondary outcomes included complete resolution of urgency urinary incontinence, quality of life, use of catheters, and adverse events.ResultsOf 249 women who underwent randomization, 247 were treated, and 241 had data available for the primary outcome analyses. The mean reduction in episodes of urgency urinary incontinence per day over the course of 6 months, from a baseline average of 5.0 per day, was 3.4 in the anticholinergic group and 3.3 in the onabotulinumtoxinA group (P=0.81). Complete resolution of urgency urinary incontinence was reported by 13% and 27% of the women, respectively (P=0.003). Quality of life improved in both groups, without significant between-group differences. The anticholinergic group had a higher rate of dry mouth (46% vs. 31%, P=0.02) but lower rates of catheter use at 2 months (0% vs. 5%, P=0.01) and urinary tract infections (13% vs. 33%, P<0.001).ConclusionsOral anticholinergic therapy and onabotulinumtoxinA by injection were associated with similar reductions in the frequency of daily episodes of urgency urinary incontinence. The group receiving onabotulinumtoxinA was less likely to have dry mouth and more likely to have complete resolution of urgency urinary incontinence but had higher rates of transient urinary retention and urinary tract infections.

Project description:ObjectivesThe objective of this study was to compare efficacy and adverse events between 100 U and 200 U of onabotulinumtoxinA for 6 months in women with nonneurogenic urgency incontinence.MethodsThis is a secondary analysis of 2 multicenter randomized controlled trials assessing efficacy of onabotulinumtoxinA in women with nonneurogenic urgency incontinence; one compared 100 U to anticholinergics and the other 200 U to sacral neuromodulation. Of 307 women who received onabotulinumtoxinA injections, 118 received 100 U, and 189 received 200 U. The primary outcome was mean adjusted change in daily urgency incontinence episodes from baseline over 6 months, measured on monthly bladder diaries. Secondary outcomes included perceived improvement, quality of life, and adverse events. The primary outcome was assessed via a multivariate linear mixed model.ResultsWomen receiving 200 U had a lower mean reduction in urgency incontinence episodes by 6 months compared with 100 U (-3.65 vs -4.28 episodes per day; mean difference, 0.63 episodes per day [95% confidence interval (CI), 0.05-1.20]). Women receiving 200 U had lower perceptions of improvement (adjusted odds ratio, 0.32 [95% CI, 0.14-0.75]) and smaller improvement in severity score (adjusted mean difference, 12.0 [95% CI, 5.63-18.37]). Upon subanalysis of only women who were treated with prior anticholinergic medications, these differences between onabotulinumtoxinA doses were no longer statistically significant. There was no statistically significant difference in adverse events in women receiving 200 U (catheterization, 32% vs 23%; adjusted odds ratio, 1.4 [95% CI, 0.8-2.4]; urinary tract infection, 37% vs 27%; adjusted odds ratio, 1.5 [95% CI, 0.9-2.6]).ConclusionsA higher dose of onabotulinumtoxinA may not directly result in improved outcomes, but rather baseline disease severity may be a more important prediction of outcomes.
Project description:Introduction and hypothesisIntradetrusor onabotulinumtoxinA (BTX) and sacral neuromodulation (SNM) are effective treatments for refractory urgency urinary incontinence/overactive bladder (UUI/OAB). BTX carries a risk of urinary tract infection (UTI), which is concerning for the development of multidrug resistant (MDR) UTI. We hypothesized that BTX might carry a higher risk of UTI and MDR UTI compared with SNM and that UTI and MDR UTI risk might increase after repeat BTX injection.MethodsThis retrospective cohort study included women undergoing BTX or SNM for refractory UUI/OAB in 2012-2016. UTI and MDR UTI were assessed up to 1 year post-treatment or until repeat treatment and compared between initial BTX and SNM and between repeat BTX injections. Univariate analyses included Chi-squared and Fisher's exact tests and generalized linear models (GLM) with logit link function. Multivariate analyses used GLM to assess the best predictor variables for any UTI.ResultsOne hundred and one patients were included (28 BTX, 73 SNM). Rates of UTI (39.3% [95% CI 21.5, 59.4] BTX vs 37.0% [95% CI 26.0, 49.1] SNM) were similar in the two groups at all time intervals. One MDR UTI occurred after SNM. Risk of UTI did not increase with repeat BTX (11 out of 28 [39.3%], 6 out of 17 [35.3%], and 4 out of 7 [57.1%] after 1, 2, and ≥ 3 treatments respectively; p = 0.62). Multivariate analysis found that history of recurrent UTI (OR 2.5, 95%CI 0.98-6.39) and prolapse repair (OR 4.6, 95%CI 1.23-17.07) had increased odds of UTI.ConclusionsRates of UTI were similar in patients undergoing BTX and SNM. MDR UTI was rare. Patients with prior prolapse repair or recurrent UTI may be at a higher risk of UTI after either procedure.
Project description:We present the rationale for and design of a randomized, open-label, active-control trial comparing the effectiveness of 200 units of onabotulinum toxin A (Botox A®) versus sacral neuromodulation (InterStim®) therapy for refractory urgency urinary incontinence (UUI). The Refractory Overactive Bladder: Sacral NEuromodulation vs. BoTulinum Toxin Assessment (ROSETTA) trial compares changes in urgency urinary incontinence episodes over 6 months, as well as other lower urinary tract symptoms, adverse events and cost effectiveness in women receiving these two therapies. Eligible participants had previously attempted treatment with at least 2 medications and behavioral therapy. We discuss the importance of evaluating two very different interventions, the challenges related to recruitment, ethical considerations for two treatments with significantly different costs, follow-up assessments and cost effectiveness. The ROSETTA trial will provide information to healthcare providers regarding the technical attributes of these interventions as well as the efficacy and safety of these two interventions on other lower urinary tract and pelvic floor symptoms. Enrollment began in March, 2012 with anticipated end to recruitment in mid 2014.
Project description:ObjectiveTo systematically review outcomes in patients with refractory overactive bladder (OAB) patients who underwent sacral neuromodulation therapy (SNM) therapy after unsuccessful onabotulinumtoxinA (BTX) therapy, and to compare outcomes with those who SNM as initial therapy.MethodsA systematic search of Cochrane Library, Pubmed and Embase databases from July 2002 to November 2019, to analyze randomized controlled trials and retrospective studies of SNM therapy after failed initial BTX therapy. Two reviewers independently screened the studies and extracted data. A quality assessment of the included literature was conducted using Newcastle-Ottawa Scale (NOS), and Stata 12.0 software was used to conduct a meta-analysis of the collected data.ResultsA total of seven studies involving 319 patients were finally included. The success rate in refractory OAB patients who used SNM therapy after failed BTX therapy was 58.5%, 95% CI (0.47-0.70). There was no significant difference between refractory OAB patients who chose SNM as replacement therapy after failed BTX therapy and those who used SNM therapy as first choice [RR = 0.96, 95%CI (0.72-1.26), P = 0.735].ConclusionOAB patients for whom an initial choice of BTX therapy ends in failure or dissatisfaction may consider switching to SNM therapy. There is no difference in outcomes between these patients and those whose first choice was SNM therapy.
