SUFU 2021: Does Percutaneous Tibial Nerve Stimulation Predict Outcome to Sacral Nerve Stimulation?

( This was a retrospective review of hospital databases since 2014 to collect all patients who had percutaneous tibial nerve stimulation (PTNS) and who subsequently had a sacral nerve stimulation (SNS) trial performed in two tertiary hospitals with the aim to determine if PTNS response is a reliable indicator to subsequent SNS trials.

A 50% reduction in overactive bladder (OAB) symptoms (frequency- volume charts) was considered a positive response. There were 15 patients who had PTNS and subsequently a trial of SNS implant. All patients had previously poor response to PTNS treatment and 6 of them also failed the SNS trial. 9 patients had a successful SNS trial and proceeded with the second stage battery implantation with continued success. The difference in response rates between the PTNS and the SNS trial was statistically significant. The PTNS response did not predict the SNS trial outcome.
