Sling vs Botox for Mixed Incontinence


Brief description of study

The primary aim is to compare the effectiveness of intradetrusor injection of 100 unit injection of Botulinum toxin A to mid-urethral sling for change in MUI symptoms 6 months following treatment.

Detailed Study Description

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 is 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.

A supplemental study will characterize baseline putative proteins/protein pathways in women with MUI associated with change in UDI after treatment with MUS or onabotulinum toxin A.
