Comparative Study Clinical TrialUrodynamic changes and response rates in patients treated with permanent electrodes compared to conventional wire electrodes in the peripheral nerve evaluation test.
Sacral neuromodulation having become established as an essentially effective new therapeutic modality, both in patients with anticholinergic-therapy refractory overactive bladder (OAB) and with chronic urinary retention. It is important to establish which patients might profit from this kind of therapy in order to ensure, by means of a peripheral nerve evaluation (PNE) test, that the implantation of a permanent stimulating device is effective. In a retrospective study we compared the urodynamic outcome of two different techniques (implantation of the permanent neurostimulation electrodes so-called "two-stage-implantation" vs. conventional PNE). ⋯ The results of this study show that application of permanent quadripolar electrodes during PNE prior to chronic neuromodulator implantation leads to significantly higher responder rates and enables more efficient patient selection.
