Study Summary

Recognition of interstitial cystitis (IC)/bladder pain syndrome (BPS) is increasing. There is a dire need to develop effective treatment options for these patients as it manifests as more than a physical disease, affecting general and psychological health as well. Existing trials comparing varying bladder instillation formulations have not identified an optimal bladder instillation therapy, however existing studies support combined heparin and alkalinized lidocaine bladder instillation as an affordable and effective treatment for IC/BPS. Additionally, intradetrusor onabotulinumtoxinA injection has been well established for the treatment of overactive bladder (OAB), a constellation of symptoms similar to that of IC/BPS. OnabotulinumtoxinA has now come into the forefront for treatment of OAB due to its efficacy, safety profile, and absence of cognitive effects related to the previous mainstay anticholinergic treatment. While both bladder instillation and onabotulinumtoxinA therapy have been shown to be effective for treatment of IC/BPS, a direct comparison of these treatments has not been performed. We therefore designed a randomized controlled trial to compare the efficacy of heparin with alkalized local anesthetic bladder instillation versus intradetrusor onabotulinumtoxinA injection in treating IC/BPS symptoms.
