Over Active Bladder Instillation Study - Botox

The primary objective of this study is to evaluate the efficacy of catheter-based instillation of a solution of Botox/DMSO as a novel method for treating women with overactive bladder (OAB) and secondary urinary incontinence who have failed oral pharmacologic therapy. This study will test the broad hypothesis that administration of Botox/DMSO instillations into the bladder with a urethral catheter can significantly improve symptoms and quality of life in patients with OAB when compared to DMSO installations alone. Explicitly, we hypothesize that scores on the validated Incontinence Quality of Life (I-QOL) questionnaire of women with OAB who receive Botox/DMSO instillation will be much improved at three-month follow-up compared to similar women receiving DMSO instillation alone. Our long-term goal is to offer women with detrusor hyperreflexia or OAB a less invasive alternative to surgery and an alternative to anticholinergic by mouth medications. In support of this effort, we are proposing a randomized, double-blind, placebo controlled clinical trial to be conducted in the Department of Urology at Mayo Clinic, Jacksonville, Florida. Note: The study was terminated early in July of 2011 due to an extended medical absence of the Principal Investigator.
