Abstract Objective To evaluate the morphological changes of the levator hiatus (LH) under different conditions in elderly women with stress urinary incontinence (SUI) base on three-dimensional ultrasound. Methods Thirty elderly female SUI patients from June 2017 to May 2018 in Dayi Hospital Affiliated to Shanxi Medical University ("our hospital" for short) were selected as the case group, while 30 cases taken physical examination in our hospital and excluded from SUI were selected as control group. Three dimensional reconstruction technology was used to measure the morphological changes of the pelvic diaphragm in three states of resting, maximum voluntary contraction (MVC) and Valsalva, including the characteristic parameters of anterior and posterior diameter (LHap), transverse diameter (LHt), circumference (LHL), area (LHarea), as well as the pubic visceral muscle thickness. Results At the resting state, LHt and LHarea in the case group were significantly increased compared with the control group (P < 0.05). In MVC state, LHaP, LHt, LHL and LHarea were increased in the case group compared with the control group, and the differences in LHaP and LHt between two groups were statistically significant (P < 0.05). Under the condition of Valsalva, LHt, LHL, LHarea, and thickness of pubic visceral muscle increased in the case group compared with the control group(P < 0.05), while LHap had no statistical significance (P > 0.05). Conclusion Based on three-dimensional ultrasound, significant differences can be observed in morphological measurements of the levator hiatus in elderly women with SUI in different states, which is helpful for the diagnosis and evaluation of SUI in elderly women.
