: What This Test Measures

: The test measures the cross-sectional area of the pelvic floor region using two-dimensional ultrasound imaging. This gives your clinician a picture of the size and shape of the pelvic floor opening, which can relate to muscle tone and support.

: How the Test Is Done

: A trained sonographer or clinician places an ultrasound probe to view the pelvic floor and captures images. From these images, the area is measured. The test is quick, does not use radiation, and is usually painless, though you may feel some pressure.

: Why Your Clinician May Order It

: Your clinician may order this test to evaluate pelvic floor function, investigate symptoms such as pelvic pressure or leakage, or monitor changes over time. It is often used alongside your symptoms and physical exam.

: What to Expect

: You may be asked to empty your bladder or to perform certain movements, such as squeezing your pelvic floor muscles, during the scan. Your clinician will explain any preparation. Results are interpreted together with your history and other tests.
