PTNS, or percutaneous tibial nerve stimulation is a procedure used once weekly for 12 weeks to help control bladder urgency and loss of control. In this procedure, a small needle (like an acupuncture needle) is placed over the tibial nerve – just above the inner side of the ankle. A small amount of electrical current is delivered through the needle and the tibial nerve is stimulated, which causes stimulation of the nerves around the bladder leading to the brain. The nerve stimulation leads to decreased urgency and urination. The electrical pulses help block the nerve signals causing the bladder to be overactive.
InterStim Therapy is an FDA-approved treatment for overactive bladder and urinary retention. With InterStim Therapy, an implantable device sends mild electrical pulses to the sacral nerves to reduce symptoms of bladder control problems. InterStim requires a surgical procedure and has been used for a number of different symptoms, including:
- Urinary incontinence
- Overactive bladder (OAB)
- Urinary retention: the inability to empty the bladder
- Fecal incontinence: the inability to control bowel movements causing stool to leak unexpectedly from the rectum.
While both PTNS and the InterStim can be very effective for bladder and bowel issues, they are not for everyone. For either of these interventions, a careful and thorough assessment by a urologist familiar with MS is needed before any treatment plan is decided upon.
