Objective To explore and analyze the efficacy of electrical stimulation combined with pelvic floor muscle training in the treatment of postpartum stress urinary incontinence in primiparous women. Methods: A total of 80 primiparous parturients with postpartum stress urinary incontinence admitted to our hospital from January 2019 to January 2020 were divided into a control group (pelvic floor muscle training treatment, n=40 cases) and a research group (electric stimulation combined with pelvic floor muscle training treatment, n=40 cases) according to the random number table. The efficacy was compared, and the urination and pelvic floor muscle function rehabilitation of primiparous parturients before and after treatment were recorded. Results The clinical efficacy rate of primiparous parturients in study group was 92.50%, which was higher than that in control group (P<0.05). After treatment, the average daily single urine volume of the research group was (150.26±15.15)ml, which was more than that of the control group. Besides, the daily average urination times and the daily average urinary incontinence times of the research group were (9.52±1.13) and (4.17±0.58) respectively, which were less than those of the control group (P<0.05). The levels of VSP and VRP of primiparous parturients in the study group after treatment were (68.05±6.63) and (55.29±5.47)cmH2O, respectively, which were higher than those in the control group (P<0.05). Conclusion The combined use of electrical stimulation and pelvic floor muscle training in the treatment of postpartum stress urinary incontinence among primiparous women is effective and reliable. It can effectively restore the pelvic floor muscle function of primiparous women and reduce the occurrence of stress urinary incontinence, thus promoting their postpartum rehabilitation process, which is worthy of promotion.
