Percutaneous Tibial Nerve Stimulation
Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive neuromodulation treatment for use in overactive bladder and associated symptoms of urinary urgency, urinary frequency and urge incontinence when more conservative measures have failed. In an outpatient setting, with the patient in a sitting position, a very small needle is inserted beneath the skin just above the ankle (a bit like acupuncture), and attached to a handheld pulse generator unit that electrically stimulates the posterior tibial nerve. This stimulation sends signals back to nerves controlling the bladder and pelvic floor muscles. Treatment lasts 30 minutes per week for 12 weeks. If and when symptoms recur, patients may return occasionally for maintenance treatment.
