[Electrostimulation of nerve roots in neurogenic bladder]

Thirty per cent of the patients with spinal injuries present chronical urinary problems. For these, G.S. Brindley's technique represents an important progress. It includes a section of posterior roots to control detrusor hyperexcitability and a stimulation of anterior roots to empty the bladder. The equipment is now perfectly reliable and the technique has been defined. Indications are essentially unstable bladders with incontinence and certain hypoactive bladders. The following results were obtained: continence is obtained in 90% of patients; complete bladder emptying in the majority of cases with very marked reduction of urinary infections; improvement of erection and regularization of intestinal transit. The complications of the surgery are uncommon but serious (CSF leaks, postoperative denervations, sepsis and material failure).
