Percutaneous tibial nerve stimulation (PTNS), also known as posterior tibial nerve stimulation, is one of the treatments we provide at the Bladder Care Centre. PTNS is used to treat overactive bladders (OAB), as well as, symptoms of urge incontinence, urinary frequency and urinary urgency.

During the procedure, the patient sits or lays down comfortably with one leg elevated. First, a surface electrode pad is adhered under the foot. Then, an electrode with a fine needle is inserted into the inner part of the ankle by one of our healthcare staff. The electrode is then connected to a pulse generator which sends an electrical pulse through the needle to the sacral plexus along the tibial nerve.

A number of studies have shown, that the sacral nerve plexus regulates the function of the pelvic floor and bladder activity. Additionally, past studies have indicated that there are benefits and favorable results with continuous PTNS therapy. Each treatment lasts for 30 minutes, once a week, for 3 months. PTNS is a low-risk procedure. Side effects with PTNS treatments are usually momentary and minor; which includes mild pain, skin inflammation and bleeding.
