Abstract：Objective To explore the characteristics of pelvic floor ultrasound in women with pelvic floor dysfunction.Methods A total of 968 female patients with pelvic floor dysfunction admitted to Sanming Second Hospital,Fujian Province from September 2018 to August 2020 were selected as the observation group.A total of 968 female patients with non-pelvic floor dysfunction admitted to Sanming Second Hospital,Fujian Province from September 2018 to August 2020 were selected as the reference group.Pelvic floor ultrasound was used to diagnose the disease in both groups clinically.The ultrasound results of constrictive anal state,the resting state,and Valsalva test state were compared.Results The anteroposterior diameter(M)of levator ani muscle hiatus by ultrasound at the constrictive anal state in the observation group was(7.11±1.39)cm,and the transverse diameter(N)of levator ani muscle hiatus by ultrasound at the constrictive anal state in the observation group was(6.79±1.29)cm,both of which were longer than(5.53±1.29)cm and(5.10±1.03)cm in the control group;the angle(γ)between the left and right branches of levator ani muscle by ultrasound at the constrictive anal state in the observation group was(87.92±11.13)°,and the hiatus area(A)of levator ani muscle by ultrasound at the constrictive anal state in the observation group was(19.95±3.39)cm2,both of which were higher than those of the control group of(74.65±9.45)° and(12.55±2.52)cm2;the pectineal visceral muscle thickness(C)by ultrasound at the constrictive anal state of the observation group was(0.99±0.37)cm,which was thicker than that of the control group of(0.81±0.29)cm,the differences were statistically significant(P＜0.05).The ultrasound M and N of the observation group in the resting state were(6.69±1.27)cm and(6.53±1.25)cm,both longer than those of the control group of(5.65±1.05)cm and(5.12±1.06)cm;the γ of the observation group in the resting state was(85.65±10.03)°,A of the observation group in the resting state was(18.55±3.23)cm2,higher than(73.27±8.67)° and(13.12±2.19)cm2 in the control group;the C of the observation group in the resting state was(0.96±0.32)cm,thicker than(0.82±0.23)cm in the control group,and the differences were statistically significant(P＜0.05).Ultrasound M and N of Valsalva status in the observation group were(7.12±1.39)cm and(6.83±1.41)cm,both longer than those in the control group of(5.69±1.30)cm and(5.44±1.37)cm;the γ of Valsalva status in the observation group was(88.25±11.43)°,A of Valsalva status in the observation group was(19.95±3.53)cm2,both higher than(72.43±8.95)° and A(15.69±3.03)cm2 in the control group;the C of Valsalva status in the observation group was(0.99±0.36)cm,thicker than(0.77±0.30)cm in the control group,the differences were statistically significant(P＜0.05).Conclusion The use of pelvic floor ultrasound can provide information for the effective diagnosis of female pelvic floor dysfunction
