Application and evaluation value analysis of PFU in PSUI

Objective: This study was designed to explore the application and evaluation values of pelvic floor ultrasound (PFU) in patients with postpartum stress urinary incontinence (PSUI). Methods: 31 patients treated in our hospital from January 2019 to December 2019 for SUI 6 weeks after delivery, and 40 healthy puerperants were included as the study objects for PFU. The 2 groups were compared for bladder neck rotation angle (BNRA) (θ), poster urethrovesical angle (PUVA) (Ar, As), distance from the bladder neck to the midpoint of synchondroses pubis (Br, Bs), bladder mobility (Mu), formation rate of internal urethral orifice, and the characteristics reflected on the 3D sonogram of urogenital hiatuses. Results: (1) puerperants in the SUIG showed higher values of θ, Ar, As, Br, Bs and Mu as compared with those healthy ones in the CG (P<0.05); (2) puerperants in the SUIG were observed with abnormal urogenital hiatuses or dilatation, manifested as deformation and abnormal enlargement, etc.; (3) the formation rate of internal urethral orifice was 74.19% (23/31) in the SUIG and 10.00% (4/40) in the CG (X2=3.903, P<0.001). Conclusion: significant differences were found between the PSUI puerperants and healthy puerperants in the signs of pelvic floor. The severity and prognosis of SUI puerperants could be evaluated based on PFU signs to guide the clinical treatment.
