The following information may help to address your question:
Neuromodulation therapy involves the stimulation of nerves to the bladder leaving the spine. The FDA has approved a device called InterStim for this purpose. Your doctor will need to test to determine if this device would be helpful to you. The doctor applies an external stimulator to determine if neuromodulation works in you. If you have a 50 percent reduction in symptoms, a surgeon will implant the device. Although neuromodulation can be effective, it is not for everyone. The therapy is expensive, involving surgery with possible surgical revisions and replacement.
Other treatments that have been tried with little success include hormonal manipulation, pharmacologic therapy, and injections of botulinum toxin.
