Comparison of the Treatment of Refractory Bladder Pain Syndrome With Dimethyl Sulfoxide (DMSO) Alone and DMSO as a Carrier Molecule for Botulinum Toxin A Instillation.

Detailed Summary

The purpose of this research study is to evaluate the efficacy of intravesical botulinum A toxin and DMSO in women with bladder pain syndrome who have not responded to first-line treatments. Bladder pain syndrome is suprapubic pain with bladder filling as well as frequency, urgency, and nocturia in the absence of urinary tract infection or other pathology. DMSO has been shown to reduce pain in women with bladder pain syndrome as well as increase bladder absorption of various drugs. Botulinum toxin A has also been shown to improve pain in women with bladder pain syndrome when injected into the bladder suburothelium via a cystoscope. The main objective of this study is to assess if DMSO can deliver botulinum toxin to the suburothelium of the bladder to produce the same effect as direct injection of Botulinum toxin and a better effect than DMSO alone.
