Objective: To explore the predictive effect of pelvic floor ultrasound parameters on stress urinary incontinence after cesarean section. Methods: The pregnant women who underwent cesarean section in our hospital from April 2021 to April 2022 were selected as the study subjects. Fifty pregnant women with SUI within 6 months after delivery were selected as the study subjects in the experimental group. However, 50 patients who underwent cesarean section for 6 months after delivery and did not initially choose SUI were selected as the control group study subjects. The experimental content was to observe the probability of PUA, BNS, LHA, BND, URA in two groups of pregnant women under resting state. To analyze the predictive effect of ultrasound parameters on SUI after cesarean section. Results: There was no significant difference in PUA and LHA between the two groups of pregnant women at rest (P>0.05); The BNS in the resting state and the maximum Valsalva state in the experimental group were significantly lower than those in the control group. Through comprehensive collection of six data, it is possible to summarize the predictive role of pelvic floor ultrasound parameters for stress urinary incontinence after cesarean section. The data obtained by the combined diagnosis method is significantly higher than the single prediction data. Conclusion: Basin ultrasound parameters have a high predictive value for postpartum SUI after cesarean section, and combining ultrasound parameters can improve the diagnostic efficacy of postpartum SUI after cesarean section
