title: Study of somatosensory evoked potentials (SSEPs) by stimulating vagina before and after hysterectomy.
abstract: OBJECTIVE
  To assess the changing status of women after hysterectomy using the electrodiagnostic method.
  
  
  METHODS
  We compared pre- and postoperative somatosensory evoked potentials (SSEPs) through vaginal stimulation in twenty patients undergoing hysterectomy.
  
  
  RESULTS
  1) The latencies (Mean +/- SD) of the first positive peak (P1) and first negative peak (N1) in preoperative vaginal SSEP were 32.89 +/- 3.02 ms and 40.41 +/- 3.43 ms in the left side, 33.25 +/- 4.28 ms and 41.39 +/- 5.46 ms in the right side respectively. 2) The postoperative P1 and N1 latencies were 33.68 +/- 4.50 ms and 42.00 +/- 4.30 ms in the left side, 33.78 +/- 3.10 ms and 42.00 +/- 3.62 in the right side respectively.
  
  
  CONCLUSIONS
  There were no significant differences between the pre- and the postoperative vaginal SSEP by stimulating vagina in patients of hysterectomy.
