Abstract
Pelvic flour dysfunction (PFD) is one common disease in females and severely affects health and life quality. 3D ultrasound is applied due to its high accuracy and consistency, and can better reveal anatomical structure and functional alternation of body tissues and organs. This study thus investigated the morphological feature of female PFD patients using 3D ultrasound with its clinical significance. A total of 40 PFD patients admitted were enrolled in this study, in parallel with 20 cases with benign diseases as the control group. 3D ultrasound examination revealed sonogram of all patients to check the prolapse of pelvic organs. In specific, the size and area of pelvic diaphragm, and thickness of puborectalis were observed. Control patients had symmetric bilateral puborectalis, rhombic diaphragm with complete structure. PFD patients, including both natural labor and caesarean birth, had organ prolapse to different extents, as shown by higher downward of bladder neck, rotation angle of urinary tract, gall bladder bulge, incidence and distance of uterus or rectal prolapse compared to control ones (P<0.05). The diameter and area of diaphragm were higher than control group during all phases, while thickness of musculi levator ani was lower than control group (P<0.05). Those indexes were better in natural delivery over caesarean birth (P<0.05). 3D ultrasound to observe female PFD can better illustrated structure morphology, as it can measure the diameter and size of pelvic diaphragm, all of those provide evidence of PFD diagnosis.
