OBJECTIVE: This study aimed to evaluate the efficacy of electrical sacral nerve stimulation (SNS) in the treatment of urinary incontinence and urinary retention refractory to conservative treatment, and to assess the impact of urodynamic abnormalities and electrode position. MATERIAL AND METHODS:Thirty patients (10 men, 20 women) with a mean age of 59 years (range 21-79 years), all of whom had longstanding symptoms ranging from 2 to 46 years (mean 12.4 years), were subjected to a percutaneous test stimulation. Ten patients responded well, resulting in a permanent implant in nine patients. Electrode positions were determined by plain X-ray and computed tomography. RESULTS: Radiologically, a variety of positions of the temporary electrodes was seen. In the implanted patients, long-term symptom reduction varied over time, ranging from total relief to partial or total recurrence of symptoms. CONCLUSIONS:SNS is a new promising option for the treatment of urge incontinence. Refined instruments for proper patient selection and the optimal way to position the electrode remain to be developed.
