What is a Urodynamic Test?
Urodynamic, or urodynamic testing, is an examination to assess whether the bladder is still functioning properly. Our bladder has two main functions as follows:
The first function is to store urine, and when it is full, we feel the urge to urinate, which leads to the second function: to expel urine.
Many patients with urinary problems may feel unusual symptoms but cannot specify where the abnormality is. The Urodynamic test helps identify the cause of difficulty or abnormal urination, so treatment can be targeted accurately.
Who Needs to Undergo Urodynamic Testing?
Both female and male patients who have urinary tract problems, such as
- Urinary incontinence
- Urine leakage
- Incomplete urination
- Frequent urination
Basic tests, urine tests, or X-rays may detect some problems, but in some patients where the doctor finds the issue more complex than expected, further in-depth testing is necessary to clarify which part is abnormal. Urodynamic diagnosis provides more accurate answers.
Frequently Asked Questions about Urodynamic or Urodynamic Testing
Q: For elderly people with only mild symptoms, can they still undergo the test if they want to?
A: In this case, the doctor will take a history to consider how necessary the test is because the term “mild” varies from person to person. If there are suspicious symptoms, the test can be done.
Q: How is the Urodynamic test performed?
A: The test takes about 1 hour. The doctor will insert a small catheter about 2-3 mm in diameter, similar to a small yogurt straw, into the urethra, and an additional catheter will be inserted into the rectum for men or the vagina for women to measure abdominal pressure. This helps determine how the bladder functions and identify any abnormalities.
Q: For women who frequently experience urine leakage, is it really due to aging or previous childbirth?
A: Aging or pelvic muscle surgery during childbirth is just one factor causing muscle relaxation. This test helps doctors diagnose whether the problem is due to pelvic muscle relaxation or weak sphincter muscles.
Q: Can young children have urinary tract problems?
A: For children, urinary tract problems often involve neurological issues. In cases with other system abnormalities and combined urinary and fecal problems, this test helps identify the issues more clearly.
Q: How should one prepare before undergoing Urodynamic testing?
A:
- The patient must not have a urinary tract infection. Usually, the patient will see a doctor for an initial examination. The patient may need to take laxatives or have a bowel cleanse because the test involves inserting a catheter into the rectum.
- No need to fast or avoid drinking water.
- Patients with chronic diseases or on regular medication can take their medications as usual.
- For those taking medications for urinary tract diseases, consult the doctor whether to stop the medication to avoid affecting the bladder test.
Q: How long does it take to get the test results?
A: Results are available immediately after the test. The results are presented as numbers and graphs, which the doctor will interpret and explain to the patient right away. After the test, patients can resume normal daily activities immediately, though there may be slight irritation for 1-2 days, which will resolve on its own.
