Application of intelligent pelvic floor ultrasound combined with multi-planar imaging in the assessment of postpartum SUI and POP / 中国医学装备

ABSTRACT

Objective:To explore the application of intelligent pelvic floor ultrasound combined with multi-planar imaging in the assessment of postpartum stress urinary incontinence(SUI)and pelvic organ prolapse(POP).Methods:A total of 516 delivery women who delivered in hospital and underwent voluntarily pelvic floor ultrasound were retrospectively selected.They were divided into SUI group(55 cases),POP group(187 cases)and normal group(274 cases)according to the results of clinical diagnosis.The resting state and a series of ultrasound parameters included bladder neck symphyseal distance(BSD),posterior urethrovesical angle(PUVA),urethral tilt angle(UTA)and bladder neck descent(BND)under the maximum Valsalva action among three groups were observed and compared.In addition,the accuracy of intelligent pelvic floor ultrasound combined with multi-planar imaging in assessing SUI and POP among three groups also were observed and compared.Results:Under the resting state,the BSD and PUVA of the SUI group were respectively lower than those of the normal group,and UTA of SUI group was higher than that of the normal group,and the differences were statistical significance(t=2.008,t=2.012,t=2.392,P<0.05).Under the maximum Valsalva action,the BSD and PUVA of the SUI group were respectively lower than those of the normal group,and UTA of the SUI group was higher than that of the normal group,and the differences were statistical significance(t=2.265,t=9.144,t=3.728,P<0.05),and the BND of the SUI group was significantly higher than that of the normal group(t=11.861,P<0.05).Under the resting state,the BSD and PUVA of the POP group were respectively lower than those of the normal group,and UTA of the POP group was significantly higher than that of the normal group(t=2.139,t=3.179,t=2.817,P<0.05),and the differences were statistical significance.Under the maximum Valsalva action,the BSD and PUVA of the POP group were respectively lower than those of the normal group,and the UTA of the POP group was significantly higher than that of the normal group,and the differences were statistical significance(t=3.748,t=12.293,t=4.396,P<0.05),and the BND of POP group was significantly higher than that of the normal group(t=20.855,P<0.05).The accuracy,sensitivity and specificity of intelligent pelvic floor ultrasound combined with multi-planar imaging were respectively 97.87%,94.44%and 98.55%in assessing SUI,and they were respectively 97.61%,97.31%and 97.82%in assessing POP.The result of Kappa consistency test indicated the consistency between the intelligent pelvic floor ultrasound combined with multi-planar imaging and the clinically diagnostic results was strong in assessing SUI and POP(Kappa=0.923,Kappa=0.950,P<0.05).Conclusion:The intelligent pelvic floor ultrasound combines with multi-planar imaging can effectively diagnose the SUI and POP of postpartum by intelligent assessing the changes of pelvic floor structure and function of delivery woman,which has favorably clinical application value.
