What is a Urodynamic Test?
What’s the idea behind doing urodynamic tests?
Urodynamic testing may be performed in certan cases when:
- You have moderate to severe involuntary urine release.
- Other tests don’t determine the causes leading to incontinence.
- Your doctor doubts that there seems more than one cause for the incontinence.
- You’re considering having a surgery.
They may also prove helpful in determining other causes of incontinence. These tests play a significant role in case surgery’s being considered for the problem. This is to ensure that the right operation is carried out. A majority of urodynamic tests focus on the ability of the bladder for storing urine and emptying regularly and completely.
However, there are some urodynamic tests that are easy and can be performed in a doctor’s office. There are other tests that require sophisticated instruments for measuring the amount of pressure experienced by the bladder and urethra. They can cost an arm and a leg.
Requirements for basic urodynamic testing
- You’ll be informed to make it for testing with a full bladder.
- While urinating into a container, the urine volume and the rate at which the bladder is emptied are measured.
- The doctor inserts a thin, flexible tube (catheter) into the bladder through the urethra. And the volume of any urine remaining is gauged. Know that a minor burning sensation may take place on the insertion of the catheter.
- The bladder may be filled with water through the catheter just before you feel the urge to pass urine. At this point, the amount of water in the bladder is gauged.
When we talk about more sophisticated testing, it involves using electodes which are placed into the rectum for measuring the electrical activity of the muscles while the bladder’s filled. This test is generally does not take place.
What about the results?
Normal results indicate that the amount of fluid left in the bladder post passing the urine, when you have a strong desire for urinating, and when you are not able to hold back urine within normal ranges.
One or more of the following may be the case:
- After urinating more than a normal amount of fluid is left in the bladder. When a large amount of urine remains in the bladder it proposes that the flow of the urine out of the bladder is somewhat blocked or the bladder muscle isn’t able to contract the way it should be to force all the urine out.
- The bladder consists of less fluid or more fluid than deemed normal when the patient feels the first urge to urinate.
- You aren’t able to hold urine when the bladder has less than the normal amount of fluid for a majority of people.
Urodynamic tests are often carried out for examining urinary continence. During these tests, one’s bladder is filled and then emptied. At the same time, pressure readings are taken from the bladder and abdomen.
