Percutaneous radiofrequency sacral rhizotomy in the treatment of the hyperreflexic bladder.

Percutaneous radiofrequency rhizotomy was performed on 7 patients with a hyperreflexic bladder to augment bladder capacity and to make intermittent clean catheterization more feasible or stop precipitous micturition. Urodynamic evaluations were done before and after rhizotomy. A successful result was achieved in 6 patients. Patient selection and methodology are discussed and some of the previously reported series of rhizotomies are compared to the present study.
