MUSA
Mixed Urinary Incontinence: Mid-urethral Sling vs. Botox A
Mixed urinary incontinence (MUI), defined as the presence of both stress urinary incontinence (SUI) and urgency urinary incontinence (UUI), is a challenging condition for which clinicians frequently use multiple sequential treatments that have undergone limited evaluation in rigorous clinical trials. The Mixed Urinary Incontinence: Mid-urethral Sling vs. Botox A (MUSA) trial will estimate the effect of Botulinum toxin A (Botox A ®) compared to mid-urethral sling for the treatment of MUI symptoms in 146 women. MUSA is a randomized 2-arm clinical trial.
The purpose of MUSA was to:
- compare treatment with either Botulinum toxin A (Botox A ®) or mid-urethral sling for women with MUI
- characterize patient characteristics associated with treatment response
The primary objective is to estimate the effect of intradetrusor injections Botulinum toxin A (Botox A ®) compared to mid-urethral sling for treatment of MUI in 146 women 6 months after treatment. The change in severity of MUI symptoms will be measured using the Urogenital Distress Inventory.
Secondary objectives include identifying predictors of treatment failure and cost-effectiveness of treatments in this MUI population.
