Long-term follow-up of percutaneous radiofrequency sacral rhizotomy.

A series of 7 patients undergoing percutaneous radiofrequency sacral rhizotomy to change a hyperreflexic to an areflexic bladder was reported in 1978. A patient from this original series was seen for treatment nine years later with successful preservation of good vesical capacity enabling him to use Credé maneuver and intermittent catheterization to evacuate his urine. In addition, there has been no recurrence of symptoms of autonomic dysreflexia during that period.
