Anterior sacral root stimulation with dorsal rhizotomy (Brindley technique)

Anterior sacral root stimulation with dorsal rhizotomy (Brindley technique) Patients with spinal cord lesions are exposed to vesico-sphincter dysfunctions which call aggravate the vital or functional prognosis. The pathophysiological characteristics of these << neurogenic bladders >> explains the usefulness of surgical treatment. The objective o the Brindley technique is to improve both voiding and effective continence. Any patient with it stable supra-sacral spinal cord lesion (paraplegia, tetraplegia) With a reflex bladder (incontinence, vesico-sphincter dyssynergia. a resistant to medical treatment with the risk of upper urinary tract involvement) can benefit from the Brindley technique. The electrodes are placed on the anterior sacral roots in order to obtain the desired micturation. Posterior sacral rhizotomies are indispensable to the technique as they suppress detrusor and sphincter hyperreflexia and improve continence thereby protecting the upper urinary tract. About 90% of the patients considered have an improved quality of life after implantation of the Brindley stimulator. The bladder capacity was constantly improved and the majority; of the patients become continent. Micturation was excellent with low residual volume and low rate of urinary tract infections. Complications are analyzed in this review of the literature. The Brindley technique is an excellent alternative to medical treatment in these highly distressed patients. It restores satisfactory continence and improves psychological as well as economical constraints related to auto/hetero catheterisations performed several times a day.
