Comparison of sensitivity and specificity of three-dimensional pelvic floor ultrasound and conventional ultrasound in pelvic floor assessment after delivery

Objective: This study was designed to investigate the sensitivity and specificity of the three-dimensional (3D) pelvic floor ultrasound and the conventional ultrasound in pelvic floor assessment after delivery. Methods: A to-tal of 108 patients with pelvic floor dysfunction treated in our hospital were selected as the study group, and another 108 healthy subjects were included as the control group. Both groups were diagnosed by conventional ultrasound and 3D pelvic floor ultrasound, and confirmed with pathological findings. The diagnostic results of the conventional ultrasound and 3D pelvic floor ultrasound were compared, and the diagnostic conditions of various indicators in the two groups were compared. Results: The numbers of true positive cases and true negative cases diagnosed by the conventional ultrasound were 84 and 90, respectively, while the numbers of true positive cases and true negative cases diagnosed by the 3D pelvic floor ultrasound were 8 and 102, respectively (P
