Botulinum A Toxin in the Treatment of Patients With Painful Bladder Syndrome

Summary

Previous clinical observations showed that Botulinum A toxin (BoNT/A) has also an antinociceptive effect and can control the neuropathic pain. In the urologic field, recent in in vitro and in in vivo studies demonstrated that the neurotoxin is able to inhibit the release of several neurotransmitters from the bladder afferent fibers and urothelium. These neurotrasmitters as SP, CGRP, ATP, NGF and Prostaglandins are involved in neurogenic inflammation. Thus, it is reasonable to hypothesize that patients with affected by painful bladder syndrome (PBS) could benefit from BoNT/A intravesically administered. The aim of the study is to investigate the clinical and urodynamic effects of an intravesical treatment with BoNT/A in patients affected by PBS associated with increased urinary frequency, who are refractory to conventional treatments. This treatment will be compared to bladder over distention, which is considered a conventional therapy.
