Résumé du colloque

The application of electric stimulation of the sacral nerve roots has gained popularity in the last decade as a method of bladder rehabilitation. During the last 2 years, we have screened 20 patients presenting with voiding dysfunction not responding to conventional therapy at the Urodynamic Unit. All patients consented to participate in a multicenter protocol sponsored by Urosystem Inc., California. All patients had detailed their voiding symptoms in a diary: continence status, associated pain and frequency. They all underwent physical, radiological and urodynamic evaluations followed by a percutaneous nerve evaluation (PNE) of the sacral roots (S2, 3 & 4). A wire was left for a subchronic stimulation for 3-5 days. The patients were then re-evaluated. Seven patients among those showed improvement on PNE had the stimulator implanted subcutaneously with an electrode connected to the selected sacral root. One paraplegic patient is able to evacuate 50-70% of his bladder on stimulation. The 6 others showed adequate bladder emptying with no or minimal residual and their pelvic pain controlled without analgesic. The electric stimulation of the sacral roots showed to be a simple effective tool to control voiding dysfunction in selected patients.
