Urodynamic testing
Urodynamic Testing
Urodynamic testing (pronounced: yoo-roh-dy-nam-ik testing) is a series of diagnostic tests that evaluate the function of the bladder and urethra. These tests are often used to diagnose conditions that affect the lower urinary tract.
Etymology
The term "urodynamic" is derived from the Greek words "ouro" meaning urine and "dynamikos" meaning power. It refers to the study of the storage, flow, and pressure of urine within the urinary tract.
Procedure
Urodynamic testing typically involves several different tests, including:
- Cystometry (pronounced: sis-tom-uh-tree): This test measures the amount of fluid the bladder can hold, how much pressure builds up inside the bladder as it stores urine, and how full it is when the urge to urinate occurs.
- Uroflowmetry (pronounced: yoo-roh-flow-meh-tree): This test measures the volume and speed of urine during urination.
- Electromyography (pronounced: eh-lek-troh-my-og-rah-fee): This test measures the electrical activity of the muscles and nerves in and around the bladder and sphincters.
- Pressure flow study: This test measures the bladder pressure required to urinate and the flow rate a given pressure generates.
- Postvoid residual measurement: This test measures the amount of urine left in the bladder after urination.
Related Terms
- Urinary incontinence: This is a condition that involves the loss of bladder control, resulting in the involuntary leakage of urine.
- Urinary tract infection (UTI): This is an infection in any part of the urinary system, which includes the kidneys, bladder, ureters, and urethra.
- Overactive bladder: This is a condition where the bladder can't hold urine normally, which causes frequent urination and urgency.
- Neurogenic bladder: This is a condition where a person lacks bladder control due to a brain, spinal cord or nerve problem.
