Research on pelvic floor ultrasound parameters to examine the occurrence of pelvic floor organ prolapse in primiparous women after delivery
Objective To investigate the diagnostic value of pelvic floor ultrasound parameters for pelvic floor organ prolapse in primiparous women after delivery.Methods Baseline data were collected from 135 primiparous women with pelvic floor organ prolapse admitted to the Second Affiliated Hospital of Chengdu Medical College-Nuclear Industry 416 Hospital from January 2020 to December 2022.These women were categorized into the prolapse group.Additionally,baseline data from 135 primiparous women without pelvic floor organ prolapse treated in department of obstetrics and gynecology during the same period were collected and categorized into the non-prolapse group.All patients underwent pelvic floor ultrasound examination and compared pelvic floor ultrasound parameters(pelvic diaphragm fissure area,urethral tilt angle and anorectal angle),to analyze their diagnostic value for pelvic floor organ prolapse.Results At rest and during the Valsalva maneuver,the hiatal area and urethral inclination angle showed statistically significant differences between the prolapse and non-prolapse groups(t=58.190,13.027,76.720,and 8.148,respectively,P＜0.05).However,there was no statistically significant difference in the anorectal angle between the two groups(P＞0.05).Receiver operating characteristic(ROC)curve analysis showed that the AUC of pelvic floor ultrasound parameters such as pelvic diaphragm hiatus area,urethral tilt angle and combined pelvic diaphragm hiatus area and urethral tilt angle for diagnosing pelvic floor organ prolapse in patients under rest and Valsalva maneuver were all greater than 0.80,and the diagnostic value was ideal.The specificities of ultrasound parameters such as pelvic diaphragm hiatus area,urethral tilt angle and combined pelvic diaphragm hiatus area and urethral tilt angle in diagnosing pelvic organ prolapse in patients at rest were 0.993,0.993 and 0.993,respectively,and the sensitivities were 0.704,0.896 and 0.874,respectively.The specificities in Valsalva state were 0.993,0.992 and 0.993,respectively,and the sensitivities were 0.792,0.978 and 0.808 respectively.Conclusion The pelvic floor ultrasound parameters of pelvic diaphragmatic fissure area and urethral tilt angle play an important role in the diagnosis of patients with pelvic floor organ prolapse.For patients suspected of having pelvic organ prolapse,conducting a pelvic floor ultrasound examination can accurately determine their condition.
