Study of somatosensory evoked potentials (SSEPs) by stimulating vagina before and after hysterectomy.
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.
