Noninvasive Ultrasound Assessment of Detrusor Dysfunction

Noninvasive Ultrasound Assessment of Detrusor Dysfunction

The purpose of this study is to test a new ultrasound method called Quantitative Ultrasound Bladder Vibrometry to detect abnormal bladder function.

The purpose of this study is to evaluate the effectiveness of quantitative ultrasound bladder vibrometry (QUBV) as a noninvasive tool for detrusor overactivity assessment and for benign prostatic hyperplasia (BPH) treatment selection. Participants in this study will have a QUBV ultrasound performed at the same time as a urodynamic study that had been ordered as part of their regular clinical care.

Inclusion Criteria:

• Aim1:

Age >18 scheduled to undergo UDS for their clinical care for one of the included diagnoses.

-Aim2: Inclusions: Age >45 scheduled to undergo selective photovaporization of the prostate.

Exclusion Criteria:

• Aim1:Obesity (BMI >35kg/m2), known neurologic disease impacting bladder function (e.g. spinal cord injury, multiple sclerosis, Parkinson's, prior cerebrovascular accident), previous pelvic radiation therapy, previous radical pelvic surgery (such as for uterine or colorectal cancer), prior bladder surgery (including prostate resection), and pregnant or breast-feeding women.
• Aim2:Obesity (BMI >35kg/m2), known neurologic disease impacting bladder function (e.g. spinal cord injury, multiple sclerosis, Parkinson's, prior cerebrovascular accident), previous pelvic radiation therapy, previous radical pelvic surgery (such as colorectal cancer).
