Overactive Bladder Surgery
Insertion of nerve stimulators have been approved for treating overactive bladder, which is refractory (unresponsive) to other more common therapies mentioned above. These devices can modulate and rebalance the nerve stimulation responsible for OAB and hyperactive detrusor muscle.
Sacral nerve stimulation (InterStim Therapy Sacral Nerve Stimulation, Medtronic, Minneapolis, Minn.) is the most common type used. If the patient with OAB responds to a test stimulation, then the device can be surgically implanted. Another type of nerve stimulator is Urgent PC (Uroplasty, Inc., Minnetonka, Minn.), a percutaneous (delivered through the skin) tibial nerve stimulation therapy. Both of these devices are FDA-approved for OAB.
Traditional surgery is rarely used in treating overactive bladder and is reserved for cases unresponsive to all other forms of therapy. Reconstructive bladder surgery is the most commonly performed procedure.
