Use of botulinum toxin type B for the treatment of detrusor hyperreflexia in a patient with multiple sclerosis: a case report.

We describe a patient with multiple sclerosis (MS) who had detrusor hyperreflexia that was not responsive to oral medications or clean intermittent catheterization. This patient was successfully treated with 2 separate injections of botulinum toxin type B into the bladder. The results of the treatment lasted 4 months and there were no side effects. A cystometrogram (CMG) done before the botulinum toxin type B injections showed significant detrusor instability. A repeat CMG months later showed no detrusor instability. To our knowledge, this is the first reported successful use of botulinum toxin type B in a patient with detrusor hyperreflexia from MS.
