Overactive Bladder, Non Obstructive Urinary Retention Clinical Trial
Official title:
The Involvement of Pudendal Somatic Afferents in Sacral Neuromodulation Assessed by Somatosensory Evoked Potentials of the Pudendal Nerve
Sacral neuromodulation is a well-excepted minimally invasive procedure for the treatment of
overactive bladder and non-obstructive urinary retention.A tined lead with 4 stimulation
electrodes is placed through the third or fourth sacral foramen and stimulates sacral roots
in its vicinity. Since the sacral roots are mixed nerves, it is currently still unknown which
nerve fibers are stimulated (autonomic vs somatic, afferent vs efferent) and what the
mechanism of action is.
This study examines the involvement of pudendal somatic afferents by measuring somatosensory
evoked potentials elicited by stimulation of the pudendal nerve.
