Item Number: 36663, 18262

The aim is to alter the neuro-transmission from the Spinal Centre to the Bladder

Why is it done?

  • To alter the neuro-transmission from the Spinal Centre to the Bladder:
  • Refractory Over Active Bladders with Urge Incontinence (OAB)
  • Under Active Bladders (UAB)
  • Chronic Pelvic Pain
  • Faecal Incontinence
  • Causative factors:

– Undetermined
– Neurogenic causes such as Multiple Sclerosis

When at least 2 anticholinergic drugs or B-adrenergic drugs have failed to have provided an improvement in symptoms of OAB

An alternative for ISC or permanent IDC for UAB

The aim was to alter the neuro-transmission from the Spinal Centre to the Bladder

This will be a trial to see if this works for you


How is it done?

  • Sedation is administered
  • You will be placed prone (on your stomach) with lower back and buttocks exposed
  • A Needle will be placed in the S3 foramina of the sacrum and connected to an electrical current with increased frequency until the correct response is obtained
  • The correct response would be puckering of the anal sphincter as well as the movement of the big toe
  • The lead is then tunnelled under the skin
  • The Lead is attached to an external modulator and battery.
  • Pts with UAB may have permanent lead placement from the start, as effects may take up to 12 months to occur
  • If you have an OAB: you should experience a marked improvement over the previous 2 weeks
  • A minimal requirement of at least 50% improvement in urinary symptoms is 1required to progress to a full implant
  • The Temporary leads will be removed with the external module and the permanent leads may be introduced on the next procedure
  • As routine in my practice, the permanent lead is used as the temporary, therefore allowing for the exact same results as with the trial period
  • The permanent battery will be placed in a pocket created under the skin with an extension of prior incision on the subsequent procedure
  • Generally, a temporary lead is not done for an UAB, as the response may take up to 9-12 months
  • Leads for pain are placed bilaterally and in multiple sites



  • Some local discomfort may be experienced.
  • Nerve stimulator may provide abnormal sensations, which your body adjusts to.
  • A Representative from Medtronic will be in contact with you to check on your settings and responses.
  • If after a 2 weeks period of the temporary leads have shown an improved in your bladder, consideration will be given to a   permanent implant
  • If no response is obtained the leads may be removed.
  • NB! Each person is unique and for this reason symptoms may vary!
