NCT02995967

Brief Summary

The specific aim of this trial is to determine if hydrodistention at the time of intradetrusor injection of botulinum toxin A has additional benefit in patients with refractory overactive bladder (OAB) and urgency symptoms compared to intradetrusor injection of botulinum toxin A alone. Consented patients will be randomized to hydrodistention at a pressure of 80 cm H2O for 5 minutes, prior to the intradetrusor injection of 100 units of botulinum toxin A (hydrodistention group) or intradetrusor injection of 100 units of botulinum toxin A alone (botulinum toxin A alone group). The primary aim will be subjective improvement measured as change from baseline at 12 weeks using the OAB-q bother subscale.

Outcome Measures

Primary Outcomes (1)

  • Symptom Bother

    The primary outcome will be measured as change from baseline at 12 weeks using the OAB-q bother subscale which consists of eight questions assessing symptom bother with a possible score from 0 to 100 with a higher score indicating greater symptom bother.

    12 weeks

Secondary Outcomes (9)

  • Urge Urinary Incontinence Episodes

    12 weeks

  • Total Number of Voids

    12 weeks

  • Subjects Requiring Clean Intermittent Self-catheterization

    2 weeks

  • Post Void Residual Volume

    2 weeks

  • Rate of UTI

    2 weeks

  • +4 more secondary outcomes

Study Arms (2)

Botulinum toxin A alone group

ACTIVE COMPARATOR

Just the intradetrusor injection of 100 units of botulinum toxin A alone

Drug: Botulinum toxin-A

Hydrodistention group

EXPERIMENTAL

Hydrodistention at a pressure of 80 cm H2O for 5 minutes, prior to the intradetrusor injection of 100 units of botulinum toxin A

Procedure: Hydrodistention

Interventions

The hydrodistention will then be performed with the bladder filled at a pressure of 80 cm H2O and noted to be full as evidenced by no further influx of water into the bladder. This volume will be held in the bladder for 5 minutes.

Hydrodistention group

Intradetrusor injection of 100 units of botulinum toxin a

Botulinum toxin A alone group
