Objective To evaluate the diagnostic efficacy of pelvic floor ultrasound parameters in post-cesarean stress urinary incontinence (SUI) and biofeedback efficacy evaluation.
Methods A total of 215 pregnant women who underwent cesarean section were selected by simple sampling method. According to whether postpartum SUI occurred, they were divided into SUI group (n=88) and non-SUI group (n=127). The SUI group received biofeedback therapy. The ultrasonic parameters of pelvic floor were compared between the two groups. The ultrasound parameters of pelvic floor in the SUI group were compared before and after treatment.
Results Bladder neck descent (BND), urethral rotation angle (URA) as well as levator hiatal area (LHA) and posterior urethrovesical angle (PUVA) in Valsalva state of the SUI group were significantly higher than those in the non-SUI group (P < 0.05). After biofeedback therapy, the total effective rate of 88 patients with SUI after cesarean section was 94.32%. The BND, URA as well as LHA and PUVA in Valsalva state of the SUI group after treatment were significantly lower than those before treatment (P < 0.05). The area under the curve (AUC) of BND, URA, LHA and PUVA in predicting the effect of biofeedback on post-cesarean section SUI were 0.853, 0.897, 0.865 and 0.887, respectively.
Conclusion Pelvic floor ultrasound parameters are highly effective in diagnosing SUI after cesarean section and evaluating the effect of biofeedback therapy.
