Risk factors of postpartum stress urinary incontinence in primiparas: What should we care

Stress urinary incontinence (SUI) is a common clinical postpartum complication. It is necessary to explore the risk factors of postpartum SUI in primiparas to provide evidence support for preventing and reducing the occurrence of SUI.Primiparas who were delivered in our hospital from March 2019 to October 2020 were identified, the personal information and related treatment details of SUI and no-SUI primiparas were collected and analyzed. Logistic regression analyses were conducted to identify the risk factors of postpartum SUI in primiparas.A total of 612 primiparas were included, the incidence of SUI in primiparas was 32.03%. There were significant differences in the body mass index (BMI) before pregnancy, diabetes, abortion, delivery method, newborn's weight, epidural anesthesia, and duration of second stage of labor (all P < .05) between SUI and no-SUI group, and there were no significant differences in the age, BMI at admission, hypertension and hyperlipidemia SUI and no-SUI group (all P > .05). Logistic regression analyses indicated that BMI before pregnancy ≥24 kg/m2 (odds ratio [OR]: 2.109, 95% confidence interval [CI]: 1.042-4.394), diabetes (OR: 2.250, 95% CI: 1.891-3.544), abortion history (OR: 3.909, 95% CI: 1.187-5.739), vaginal delivery (OR: 2.262, 95% CI: 1.042-4.011), newborn's weight ≥3 kg (OR: 1.613, 95% CI: 1.095-2.316), epidural anesthesia (OR: 2.015, 95% CI: 1.226-3.372), and duration of second stage of labor ≥90 minutes (OR: 1.726, 95% CI: 1.084-2.147) were the risk factors of postpartum SUI in primiparas (all P < .05).The clinical incidence of SUI in primiparas is relatively high. In clinical practice, medical staff should conduct individualized early screening for those risk factors, and take prevention measures to reduce the occurrence of SUI.
