Stimulation of conus-epiconus with pisces. Further indications.

Stimulation by epidurally implanted bipolar electrodes placed upon the conus and epiconus, not only reduces pain, but also sensitive and vegetative sensations. Seven patients suffered from pain in the sacral and coccygeal region as in coccygodynia, also from sensitive and vegetative discomforts in the perineum, anus, rectum, bladder and vagina. Introduced between L 2/3, the tips of the electrodes were placed between the levels of D 10 and L 1 (6 patients) and between D 7 and D 8 (1 patient), the optimal location was found by stimulation. The stimulation was tested in procumbent standing or sitting positions before fixing the electrodes. In all 7 patients there was a reduction of symptoms.
