TNS (Percutaneous Tibial Nerve Stimulation)

Percutaneous Tibial Nerve Stimulation (PTNS) is a minimally invasive neuromodulation therapy used to treat overactive bladder (OAB) and associated symptoms like urinary urgency, frequency, and incontinence. It involves the electrical stimulation of the tibial nerve, which influences the pelvic floor and bladder function.

Mechanism: The tibial nerve, located near the ankle, is a branch of the sciatic nerve. By stimulating this nerve, PTNS modulates the neural control of the bladder and pelvic floor muscles. The exact mechanism is not fully understood, but it is believed that the electrical impulses travel up the tibial nerve to the sacral plexus, which controls bladder function.


  1. Preparation: The patient is seated comfortably with their leg supported.
  2. Needle Insertion: A fine needle electrode is inserted just above the ankle, near the tibial nerve.
  3. Stimulation: An external pulse generator delivers electrical impulses through the needle. The stimulation typically lasts for about 30 minutes.
  4. Sessions: Treatments are usually given weekly for 12 sessions, with maintenance therapy as needed.

Effectiveness: Clinical studies have shown that PTNS can significantly reduce the symptoms of OAB. Many patients experience improvement in urinary urgency, frequency, and incontinence. The success rate varies, but many patients achieve at least a 50% reduction in symptoms.


  • Non-surgical: PTNS is a minimally invasive alternative to more invasive surgical options.
  • Safety: The procedure has a low risk of complications and side effects.
  • Efficacy: Proven effective in many patients with OAB who have not responded to conservative treatments.

PTNS is a viable and effective treatment option for managing overactive bladder symptoms. It offers a non-surgical approach with minimal side effects, providing significant symptom relief for many patients. As with any medical treatment, it is important for patients to discuss the risks and benefits with their healthcare provider at Prestige Medical Group to determine if PTNS is an appropriate option for their condition.
