Abstract Objective: To analyze the changes in anatomical shape of pelvic diaphragmatic hiatus in patients with pelvic floor organ prolapse(POP) by transperineal four-dimensional ultrasound. Methods: Fifty-four patients with POP who were diagnosed by clinical examination in gynecological clinic were selected as the prolapse group. All patients were quantified by POP-Q score. There were 26 patients,who were included into mild-moderate group (I-II degree), and 28 patients in severe group (Ⅲ-Ⅳdegree). Sixty non-sterile healthy women were selected as the control group. Four-dimensional ultrasound examination was performed to compare the differences in pelvic diaphragmatic hiatus parameters among patients with different degrees of prolapse in the resting state, Valsalva movement, and constricted movement. Results: The pelvic diaphragmatic hiatus area, perimeter, and changes in the resting, Valsalva, and constricted movement were significantly different between the prolapse group and control group(P<0.05). The area of pelvic diaphragmatic hiatus and perimeter of the patients in the mild-moderate prolapse group were relatively smaller than the severe prolapse group at rest, Valsalva, and constricted movement. The differences were statistically significant (P<0.05). Conclusion: The examination of anatomical structure and functional changes of the pelvic diaphragmatic hiatus by four-dimensional ultrasound is an effective imaging method to observe POP. The prolapse is related to the size of pelvic diaphragmatic hiatus, four-dimensional ultrasound can provide an important anatomical basic for clinical diagnosis.
