    AbstractBladder pain syndrome/interstitial cystitis is characterized by bladder pain associated with urgency, frequency, nocturia, dysuria and sterile urine. Recent studies have shown that these bladder dysfunctions could originate from chronic inflammation or urothelial insult and proceed to a cascade of tissue reactions, which finally ascends to the central nervous system. Pilot studies of intravesical injection of botulinum toxin type A for bladder pain syndrome/interstitial cystitis had been introduced since 2005 with a promising result. Recent evidence suggests that botulinum toxin type A could significantly improve symptoms such as daytime frequency, nocturia, pain, quality of life and bladder capacity in bladder pain syndrome/interstitial cystitis patients. Single injection of botulinum toxin could not achieve long-term successful therapeutic result, and repeat injections could provide a better long-term success rate. However, patients with ulcer type bladder pain syndrome/interstitial cystitis might not gain a benefit from botulinum toxin type A injection. Laboratory evidence showed that botulinum toxin type A for bladder pain syndrome/interstitial cystitis injection could induce peripheral desensitization, reduces bladder chronic inflammation and decreases apoptotic signal molecules in the urothelium. The present article reviewed the recent advances of botulinum toxin type A on bladder pain syndrome/interstitial cystitis.© 2014 The Japanese Urological Association.
