title: [Posterior sacral root neuromodulation in the treatment of chronic urinary dysfunction].
abstract: OBJECTIVE
  To describe the effectiveness of sacral root neuromodulation in ameliorating symptoms of refractory voiding disfunction in our center.
  
  
  METHODS
  During the period from december 1998 throught december 2001, 31 Percutaneous Nerve Evaluation (PNE) was performed to 20 patients with refractory voiding dysfunction; a sacral nerve stimulation device was implanted in 10 patients (8 female, 2 male). The median age was 49 years. Refractory voiding dysfunction included: mixed disorders (30%), idiopathic nonobstructive chronic urinary retention (20%), urgency/frequency (20%), faecal and urinary incontinence with absence of sphincter defect (20%) and frequency (10%).
  
  
  RESULTS
  The 2 patients with frequency/urgency decreased their symptoms more than 50%, bladders were emptied without post-void residual urine in 2 patients with urinary retention, faecal and urinary incontinence in 2 patients and mixed disorders in other 3, reduced their symptoms more than 90% without residual urine. The frequency improved more than 50% in 1 patient.
  
  
  CONCLUSIONS
  Sacral Root Neuromodulation is a successful treatment in some cases of idiopathic chronic micturition dysfunction which don't respond to pharmacotheraphy or bladder retraining. The effects of neuromodulation are long-lasting and associated morbidity is low.
