Neurology and Uro dynamics RESULTS OF THE TREATMENT OF NEUROGENIC BLADDER DYSFUNCTION IN SPINAL CORD INJURY BY SACRAL POSTERIOR ROOT RHIZOTOMY AND ANTERIOR SACRAL ROOT STIMULATION

Purpose: We evaluated the results of treatment of neurogenic bladder dysfunction in spinal cord injury by sacral posterior root rhizotomy and anterior sacral root stimulation using the Finetech-Brindley stimulator.* Materials and Methods: In 52 patients with spinal cord lesions and urological problems due to hyperreflexia of the bladder complete posterior sacral root rhizotomy was performed and a Finetech-Brindley sacral anterior root stimulator was implanted. All patients were evaluated and followed with a strict protocol. A minimal 6-month foliowup is available in 47 cases. Results: Complete continence was achieved in 43 of the 47 patients with 6 months of followup. A significant increase in bladder capacity was attained in all patients. Residual urine signifi­ cantly decreased, resulting in a decreased incidence of urinary tract infections. In 2 patients upper tract dilatation resolved. In 3 patients rhizotomy was incomplete and higher sectioning of the roots was necessary. One implant had to be removed because of infection. Conclusions: The treatment of neurogenic bladder dysfunction in spinal cord injury by anterior sacral root stimulation with the Finetech-Brindley stimulator in combination with sacral poste­ rior root rhizotomy provides excellent results with limited morbidity.
