[Use of rechargeable stimulators in 2 cases of cauda equina syndrome]

The first of the 2 cases of cauda equina syndrome we report occurred following phenolization of sacral roots after a series of operations for Hirsprung disease. The second occurred after trauma from a bullet that hit the spine. Fecal and urinary incontinence and neuropathic pain in the lower extremities were present in both cases. After various treatments failed, both patients were given dual spinal stimulation for integrated treatment of both incontinence and neuropathic pain. We applied a novel approach, connecting both stimulators to a single rechargeable generator, reducing medium- and long-term costs. Fewer generator replacements (every 2-3 years with the standard approach) and fewer generator implantations (2 each time with the usual system) are required when rechargeable generators are used. Patient quality of life is thus improved. The overall cost of the implants is reduced from their second year of use.
