Objective To investigate the relationship between relevant obstetrical factors and postnatal stress urinary incontinence. Methods Standard questionnaire on international urinary incontinence was applied, which was recommended by International Continence Society(ICS). Seven hundred and eighteen primiparas from the Obstetrical Department of Hebei United University Affiliated Hospital and Qinhuangdao Maternity and Child Care Hospital were randomly selected as our subject and fill out the survey. Six hundred and seventy-three primiparas were re-examined after delivery. Their postnatal situation of urinary incontinence after 42 days was recorded. Results ( 1 )Forty-one( 6. 09% ) primiparas of 673 primiparas were diagnosed with urinary incontinence after 42 days of their parturition. There were relationship between postnatal urinary incontinence with the mode of delivery,fetus body weight,progestational body weight and body mass index,and anal contraction movements(P < 0. 05).(2)The probability of the vaginal delivery group was 7. 76%(34 / 438), higher than that in primiparas with selective cesarean section group(2. 97%(7 / 235);χ2 = 6. 1;P < 0. 05).(3) The postnatal urinary incontinence in vaginal delivery group was closely related with fetus body weight, progestational body weight,body mass index( t = 4. 316,2. 093,2. 654;P < 0. 05). Conclusion (1)The postnatal urinary incontinence is more easily appeared in vaginal delivery.(2)Progestational primiparas with light body weight,fetus with less body weight,and anal contraction movements conducted in the postpartum period,can reduce the probability of postnatal urinary incontinence.(3)Mild urinary incontinence is more likely appeared during pregnancy and in the postpartum period. Therefore,more pelvic floor muscle exercise will have a better effect on preventing and curing postnatal urinary incontinence.
