Abstract：Objective To investigate the pelvic floor four-dimensional ultrasound value of evaluation of postoperative lower urinary
tract structure and predictive of urinary incontinence in patients with pelvic organ prolapse (POP). Methods A total of 121 POP
patients who underwent surgery in our hospital from January 2019 to August 2021 were selected as the research objects. The structure
of lower urinary tract and urinary incontinence were examined by pelvic floor four-dimensional ultrasound before and after operation.
Results The levator urethra gap (LUG) value at postoperative resting state and max valsalva action (MVA), the bladder neck descent
at MVA and the levator ani fissure area at different conditions were significantly lower than those before surgery (P<0.05). There was
no significant difference in ∠α and retrovesical angle before and after surgery in different states (P>0.05). There was no significant
difference in LUG value before and after surgery in constipation state (P>0.05). Postoperative dysuria occurred in 8 cases (6.61%),
and new stress urinary incontinence occurred in 16 cases (13.22%). The proportion of patients with urinary incontinence after
operation was significantly higher than that before operation (P<0.05). After operation, 65 cases (53.72%) had urinary incontinence
through pelvic floor four-dimensional ultrasound, and 68 cases (56.20%) actually had urinary incontinence after operation. The
accuracy of pelvic floor four-dimensional ultrasound was 95.59% (65/68). The area under ROC curve predicted by pelvic floor fourdimensional
ultrasound was 0.845 (95%CI: 0.779-0.911), the sensitivity was 84.38% and the specificity was 78.75%. It showed that
pelvic floor four-dimensional ultrasound had high predictive value. Conclusion Pelvic floor four-dimensional ultrasound can evaluate
the postoperative lower urinary tract structure and predict urinary incontinence in patients with POP.
