Sacral anterior root stimulation of the bladder in paraplegics.

A Brindley-Finetech sacral anterior root stimulator has been placed intradurally in the spinal canal around the S2, 3, 4 nerve roots in six paraplegics at the Burwood Spinal Injuries Unit, Christchurch, New Zealand. The apparatus developed by Professor G. S. Brindley and the Medical Research Council in London, UK, has proved very useful in driving micturition, in achieving a dry device-free interval between electromicturitions, in reducing the incidence of urinary tract infections, and in some males in achieving a sustained erection. The clinical results are presented with a urodynamic analysis of the outcome.
