[Electrostimulation of anterior sacral nerve roots in the treatment of central neurogenic bladders. G.S. Brindley's technique. Results of the 40 first French cases].

The results of the first 40 cases who underwent implantation of a sacral anterior root stimulator (G.S. Brindley) in France are reported. One patient die two years after implantation from an unrelated cause. 39 patients are using electrostimulation with a 6 month to 8 year follow-up. 90% have a satisfactory continence and no longer require an incontinence appliance. 82% of the patients have a post-void residue of 0 to 50 cc. Urinary infection rate has dramatically decreased. Bladder capacity and compliance have increased, and urethral closure pressure has decreased according to posterior rhizotomy. Possible side effect of total posterior rhizotomy from S2 to S4 could be stress incontinence.
