摘要
目的 探讨不同分娩方式对盆底支持组织功能的近期影响.方法 选取健康初产妇553例,其中阴道分娩289例（阴道分娩组）,选择性剖宫产264例（剖宫产组）,于分娩后6周进行尿失禁问卷调查、盆底肌电图测定盆底肌肉收缩及舒张功能.结果 阴道分娩组与剖宫产组的产妇分娩后,压力性尿失禁的发生率分别为13.49%（39/289）、6.44%（17/264）,两组经比较有显著性差异（χ^2=7.55,P〈0.01）.盆底肌收缩、舒张时记录的肌电图数值中,阴道分娩组的活力值、功值均低于剖宫产组,经比较有显著性差异（t分别为14.095、31.994,均P〈0.05）.结论 选择性剖宫产产妇产后压力性尿失禁发生率较阴道分娩产妇明显降低,不同分娩方式对盆底支持组织功能的近期影响较为明显.
Objective To investigate short-tern influence of different patterns of delivery on function of pelvic floor supporting tissues of the women. Methods 553 healthy primiparae were selected, 289 of them underwent vaginal delivery（ vaginal delivery group） , and 264 of them underwent selective cesarean section （selective cesarean section group ）. All primiparae received a questionnaire survey on urinary incontinence at 6 weeks after their accouchements and electromyography （EMG） for pelvic floor muscles for contractile and relaxant functions. Results The incidence of stress urinary incontinence （SUI） in the vaginal delivery group was 13.49% （39/289） and that in the selective cesarean section group was 6.44% （17/264）, there was a significant difference between the two groups（X^2 = 7.55 ,P 〈 0.01 ）. In the recorded EMG values of pelvic floor muscle contraction and relaxation, the dynamic value and function values in the vaginal delivery group were lower than those in the cesarean section group, and there were significant differences （t = 14.095, 31. 994 respectively, both P 〈 0.05 ）. Conclusion Compared with primiparae who underwent vaginal delivery, the ineidenee of SUI among primiparae who underwent selective cesarean section is significantly lower. The short-term influences of different patterns of delivery on pelvic floor muscular functions are significant.
