What This Test Measures
Pelvic outlet pressure is assessed by inserting small tubes (catheters) into your bladder and rectum while you perform movements like coughing, straining, or bearing down. Sensors detect pressure changes in the pelvic region, helping identify abnormal pressure patterns that may indicate underlying issues.
Why It’s Done
Doctors may recommend this test if you experience symptoms like frequent urination, pelvic pain, or a feeling of incomplete emptying of your bladder or bowels. It’s also used to evaluate conditions like stress urinary incontinence, pelvic organ prolapse, or nerve-related pelvic dysfunction.
Common Conditions Evaluated
This test helps diagnose conditions affecting pelvic floor function, such as urinary incontinence, fecal incontinence, or pelvic pain syndromes. It can also assess nerve damage or muscle weakness contributing to pelvic outlet dysfunction.
What to Expect During the Test
You’ll lie on your back with small tubes inserted into your bladder and rectum. Sensors will measure pressure changes as you perform specific movements. The procedure usually takes 30–60 minutes and may involve some discomfort but is generally painless.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal pressure readings can indicate pelvic floor dysfunction, nerve damage, or structural issues like prolapse. These findings guide treatment options, such as physical therapy, lifestyle changes, or surgical interventions to improve pelvic health.
