Urodynamic

Urodynamics is the study of how the urinary system functions. It involves a series of tests that measure the efficiency of the bladder's ability to empty steadily and completely. It can also show whether the bladder is having abnormal contractions that cause leakage.

Overview

Urodynamic tests can help explain symptoms such as:

• Incontinence
• Frequent urination
• Sudden, strong urges to urinate but nothing comes out
• Problems starting a urine stream
• Painful urination
• Problems emptying the bladder completely
• Recurrent urinary tract infections

Types of Urodynamic Tests

There are several types of urodynamic tests, including:

• Cystometry: This test measures the amount of fluid the bladder can hold, the pressure inside the bladder, and how full it is when the urge to urinate begins.
• Uroflowmetry: This test measures the volume and speed of urination.
• Postvoid residual measurement: This test measures the amount of urine left in the bladder after urination.
• Electromyography: This test measures the electrical activity of the muscles and nerves in and around the bladder and the sphincters.
• Video urodynamic tests: These tests take pictures and videos of the bladder during filling and emptying.

Procedure

The procedure for urodynamic tests varies depending on the type of test. Some tests involve the use of a catheter, while others require the patient to urinate into a special container. The tests can be performed in a healthcare provider's office, a urodynamic laboratory, or a hospital.

Risks

The risks of urodynamic tests are minimal and may include discomfort and minor bleeding.

Results

The results of urodynamic tests help diagnose the cause and nature of a lower urinary tract problem.
