A test that detects urinary incontinence and assesses bladder function. Know it

Urodynamic tests for urinary incontinence are tests performed to assess bladder function and efficiency. The actual tests performed vary from person to person, and through the "Reassure Yourself" series we learn about the importance of urodynamic tests and their uses, according to the "healthlinkbc" website.

Some urodynamic tests are relatively simple and can be performed in a doctor's office, while others require expensive and sophisticated tools to measure the amount of pressure exerted on the bladder and urethra.

To perform a basic urodynamic test:

You'll be asked to take the test as your bladder is full.

During urination into a bowl, the volume of urine and the rate at which the bladder empties are measured.

A catheter is then inserted into the bladder through the urethra, and the volume of any urine remaining in the bladder is measured. The bladder may fill with water through the catheter until you feel the first urge to urinate. The amount of water in the bladder is measured at this stage and then more water can be added. During resistance to urination until bedwetting occurs.

The more complex test uses electrodes placed in the rectum to measure the electrical activity of the muscles as the bladder fills, and this test is not commonly performed.

Why does a doctor order a urodynamic test?

A urodynamic test may be performed in the following cases:

You have moderate to severe involuntary urine production.

Other tests do not determine the cause of urinary incontinence.

Your doctor suspects that there is more than one cause for your incontinence.

Perform an operation.

Test results

Normal results mean that the amount of fluid left in the bladder after urination, when you feel the need to urinate, and when you cannot hold back the urine, falls within the normal range.

Abnormal results

It can be caused by one or more of the following reasons:

- More than the normal amount of fluid left in the bladder after urination indicates a partial blockage of the flow of urine from the bladder or that the bladder muscle is not contracting properly to force urine out (excess incontinence).

The bladder contains less or more fluid than is considered normal when the first urge to urinate is felt.

Inability to retain urine when the bladder contains less normal fluid for most people.
