Abstract To explore the diagnostic value of the pelvic floor ultrasound and Green classification for the postpartum early pelvic floor structure and stress urinary incontinence (SUI) of puerperae. Methods: A total of 204 puerperae were enrolled in this study between March 2021 and March 2023. According to the occurrence of the postpartum early SUI, these puerperae were divided into group A (82 cases with SUI) and group B (122 cases without SUI). The values of bladder neck-symphyseal distance (BSD), posterior urethrovesical angle (PUA), bladder neck descent (BND) and urethral rotation angle (UR) under rest and Valsalva manoeuvre states of the puerperae were detected and were compared between the pelvic floor ultrasound and Green classification. The diagnostic value of the relevant parameters of the pelvic floor ultrasound and Green classification for the SUI of the puerperae was analyzed by receiver operator characteristic (ROC) curves. Results: Under rest state, there was no significant difference in the pelvic floor ultrasound parameters of the puerperae between the two groups (P>0.05). Under Valsalva manoeuvre state, the values of BSD, PUA, BND and UR of the puerperae in group A were significantly higher than those of the puerperae in group B, and the proportion of the type Ι of Green classification (25.6%) of the puerperae in group A was significantly lower than that (59.8%) of the puerperae in group B (all P<0.05). The results of ROC curves analysis showed that the diagnostic value of Green classification (AUC=0.579) was poor for SUI of the puerperae (P=0.057). Under Valsalva manoeuvre state, the AUC of the BSD value, PUA value, BND value and UR value of Green classification of the puerperae for their SUI occurrence were 0.758, 0.743, 0.769 and 0.705, respectively, and which had good diagnostic value for SUI (P<0.05). Conclusion: The pelvic floor ultrasound and Green classification of the puerperae can effectively evaluate the postpartum early pelvic floor structure, and the pelvic floor ultrasound can diagnose the SUI occurrence of the puerperae.
