摘要：Objectives: To evaluate vaginal and clitoral sensation before and after hysterectomy and to assess pre-and post-surgery changes in sexual function. Study design: Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina and clitoris 1 day prior to and 3 months following surgery. A survey was performed 18 months following operation to evaluate long-term changes in sexual function. Participants: Twenty-seven women, aged 30-57 years, who were admitted for elective hysterectomy. Main outcome measures: Genital sensation and reported sexual function. Results: There was significant deterioration in sensation to cold and warm stimuli at the anterior and posterior vaginal wall after surgery. Vaginal vibratory sensation thresholds tended to increase. Clitoral thermal and vibratory sensation thresholds remained unchanged before and after surgery. Of the 22 patients who participated in the follow-up survey, 17 did not report any decline in sexual function, while 4 patients reported deterioration in genital sensation and in sexual function. Conclusion: The results demonstrate quantifiable sensory loss in the vagina after hysterectomy, with preservation of clitoral sensation. Only a minority of patients reported a decline in their sexual function. These findings highlight the relative importance of clitoral as compared to vaginal sensation in sexual function.

摘要：A design of the high-current modular pulsed power generator and results of the test of this generator are presented. The generator is based on two capacitors each of 2.5 μF and 50 kV maximum charging voltage. Two multi-gaps gas spark switches with capacitive coupled triggering are used to discharge stored energy into the load. The triggering pulse with amplitude up to 70 kV and rise time of ~50 ns is supplied by three-stage Marx-generator. The output of each capacitor with multi-gaps spark switch is connected to the load by eight coaxial cables ~1 m in length. The total inductance of the generator does not exceed 200 nH. At 40 kV charging voltage this generator produces 180 kA with a quarter of period of 1.6 μs at short circuit load of ~15 nH. The generator has been used in the research of underwater electrical wire explosion. The space separation of the load and modules of generator allows one to avoid possible damages of the generator by shock waves produced during the wire explosion. In addition, this modular generator design allows to increase easily the number of modules and to reach several hundreds of kiloamperes in the load.
