Percutaneous Tibial Nerve Stimulation

Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive neuromodulation treatment marketed by Uroplasty, Inc. for use in overactive bladder and associated symptoms of urinary urgency, urinary frequency and urge incontinence when more  conservative measures have failed. (1) 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. (2)

PTNS is also being explored as a potential alternative to sacral nerve stimulation in cases of fecal incontinence. (3)
