Levator plate descent angle in pelvic floor disorders

Area of Science:

• Urogynecology
• Pelvic Floor Disorders
• Medical Imaging

Background:

• Levator plate descent angle (LPDA) is a novel parameter assessing levator plate position.
• Levator ani deficiency (LAD) compromises pelvic organ support.
• Research on LPDA and its clinical significance is limited.

Purpose of the Study:

• To investigate the relationship between LPDA and LAD in patients with pelvic floor disorders.
• To evaluate LPDA as a potential indicator of pelvic floor structural defects.

Main Methods:

• Retrospective study of 93 women with pelvic floor disorder symptoms.
• Three-dimensional pelvic floor ultrasound for LAD scoring, minimal levator hiatus (MLH), and LP4DA evaluation.
• LAD scoring system graded levator injury from 0-18 (mild, moderate, severe).

Main Results:

• A moderate negative correlation (r=-0.528) was found between LAD score and LPDA.
• Severe LAD scores correlated with lower LPDA values and larger MLH areas.
• Significant differences in age, parity, and incontinence scores were observed across LAD severity groups.

Conclusions:

• LPDA is a valuable parameter for assessing the severity of structural defects in pelvic floor disorders.
• Lower LPDA values are associated with higher LAD scores and more severe pelvic floor dysfunction.
• LPDA aids in understanding the extent of levator ani muscle injury.
