Combination therapy with botulinum toxin and bulking agent-An efficient, sustainable, and safe method to treat elderly women with mixed urinary incontinence.

ABSTRACT:

Aims

To evaluate the efficacy, sustainability and safety of combined botulinum toxin and polyacrylamide hydrogel (PAHG) therapy to treat urgency and stress components of therapy-refractory mixed urinary incontinence (MUI) in an elderly study population.

Methods

Fifty-five women with therapy-refractory MUI were treated with botulinum toxin and PAHG in one surgical procedure. Urgency urinary incontinence (UUI) and stress urinary incontinence (SUI) outcomes were separately assessed after 4 and 12 months by objective UUI episodes/24 h and cough test, subjective impact of UUI and SUI on quality of life, and subjective International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). MUI outcome was calculated by combining UUI and SUI outcomes. Complications were monitored throughout the study.

Results

At 4 months, objective cure rates were 73%, 53%, and 42%, and subjective cure rates were 71%, 52%, and 50% for SUI, UUI, and MUI. At 12 months, objective cure rates were 73%, 56%, 50% and subjective cure rates were 78%, 42%, and 40% for SUI, UUI, and MUI. The ICIQ-UI SF score decreased by 9.0 and 8.7 points after 4 and 12 months. All complications were transient and included 22% clean intermittent catheterization immediately after surgery, 33% postvoid residual volumes >100 ml at 14 days, and 13% symptomatic urinary tract infection within the first postoperative month.

Conclusions

The combination of botulinum toxin and PAHG is effective, sustainable and safe to treat therapy-refractory MUI, even in an elderly and frail study population. Patients benefit from the short surgical procedure without the need for general anaesthesia or discontinuation of anticoagulation.

Project description:BackgroundObesity is an established and modifiable risk factor for urinary incontinence, but conclusive evidence for a beneficial effect of weight loss on urinary incontinence is lacking.MethodsWe randomly assigned 338 overweight and obese women with at least 10 urinary-incontinence episodes per week to an intensive 6-month weight-loss program that included diet, exercise, and behavior modification (226 patients) or to a structured education program (112 patients).ResultsThe mean (+/-SD) age of the participants was 53+/-11 years. The body-mass index (BMI) (the weight in kilograms divided by the square of the height in meters) and the weekly number of incontinence episodes as recorded in a 7-day diary of voiding were similar in the intervention group and the control group at baseline (BMI, 36+/-6 and 36+/-5, respectively; incontinence episodes, 24+/-18 and 24+/-16, respectively). The women in the intervention group had a mean weight loss of 8.0% (7.8 kg), as compared with 1.6% (1.5 kg) in the control group (P<0.001). After 6 months, the mean weekly number of incontinence episodes decreased by 47% in the intervention group, as compared with 28% in the control group (P=0.01). As compared with the control group, the intervention group had a greater decrease in the frequency of stress-incontinence episodes (P=0.02), but not of urge-incontinence episodes (P=0.14). A higher proportion of the intervention group than of the control group had a clinically relevant reduction of 70% or more in the frequency of all incontinence episodes (P<0.001), stress-incontinence episodes (P=0.009), and urge-incontinence episodes (P=0.04).ConclusionsA 6-month behavioral intervention targeting weight loss reduced the frequency of self-reported urinary-incontinence episodes among overweight and obese women as compared with a control group. A decrease in urinary incontinence may be another benefit among the extensive health improvements associated with moderate weight reduction. (ClinicalTrials.gov number, NCT00091988.)

Project description:ImportanceUrinary incontinence is one of the most prevalent health concerns experienced by older women (aged ≥60 years). Individual pelvic floor muscle training (PFMT) is the recommended first-line treatment for stress or mixed urinary incontinence in women, but human and financial resources limit its delivery. Whether group-based PFMT performs as well as individual PFMT in this population remains unclear.ObjectiveTo assess the efficacy of group-based PFMT relative to individual PFMT for urinary incontinence in older women.Design, setting, and participantsThe Group Rehabilitation or Individual Physiotherapy (GROUP) study is a single-blind, randomized, noninferiority trial conducted in 2 Canadian research centers, from July 1, 2012, to June 2, 2018. A total of 362 community-dwelling women aged 60 years or older with symptoms of stress or mixed urinary incontinence were enrolled.InterventionsAfter an individual session conducted to learn how to contract pelvic floor muscles, participants completed 12-week PFMT as part of a group of 8 women (n = 178) or in individual sessions (n = 184).Main outcomes and measuresThe primary outcome measure was the percentage reduction in urinary incontinence episodes at 1 year, as reported in a 7-day bladder diary and relative to pretreatment baseline. Secondary outcomes included lower urinary tract-related signs, symptoms, and quality of life immediately following treatment and at 1 year. Per-protocol analysis was used.ResultsAmong 362 women who were randomized (mean [SD] age, 67.9 [5.8] years), 319 women (88%) completed the 1-year follow-up and were included in the per-protocol analysis. Median percentage reduction in urinary incontinence episodes was 70% (95% CI, 44%-89%) in individual PFMT compared with 74% (95% CI, 46%-86%) in group-based PFMT. The upper boundary of the 95% CI for the difference in the percentage reduction in urinary incontinence episodes at 1 year was lower than the prespecified margin for noninferiority of 10% (difference, 4%; 95% CI, -10% to 7%; P = .58), confirming noninferiority. Individual PFMT and group-based PFMT had similar effectiveness for all secondary outcomes at 1 year. Adverse events were minor and uncommon.Conclusions and relevanceResults of the GROUP study suggest that group-based PFMT is not inferior to the recommended individual PFMT for the treatment of stress and mixed urinary incontinence in older women. Widespread use in clinical practice may help increase continence-care affordability and treatment availability.Trial registrationClinicalTrials.gov Identifier: NCT02039830.
