If you think you have been dealing with urinary incontinence, otherwise known as the involuntary loss of urine, you may be looking for a way to get tested. Testing for incontinence not only can confirm that you should be diagnosed, but it can also find the underlying causes and can lead you to treatment options. Today, we’re going to talk about urodynamics which is the main testing option for urinary incontinence.
What do urodynamic tests look for?
Urodynamic tests are used to diagnose those who have urinary incontinence or are experiencing lower urinary tract symptoms. These tests can be given to both men and women who are dealing with urinary issues. Urodynamic tests measure:
- Muscle and nerve function
- Flow rates and other similar factors
- Pressure surrounding and in the bladder
The test takes a look at how the bladder, urethra, and sphincters are releasing and storing the urine.
What symptoms usually lead to urodynamic testing?
Most urodynamic tests are to see how well the bladder is releasing and storing urine, so these tests are often done if you are having issues with this. Here are some symptoms you may be having that will lead your doctor to urodynamic testing:
- Urine leakage, or incontinence of any type
- Overwhelming and sudden urges to use the restroom frequently
- Issues when starting urination or fully emptying your bladder
- Frequent Urinary Tract Infections (UTIs) or pain while urinating
If you are having any symptoms like these, your doctor may want to test your bladder to figure out what can be done.
What are the different urodynamic tests?
There are many different urodynamic tests that you may need to have done based on your unique circumstances. These are the main urodynamic tests:
- Postvoid residual measurement
- Pressure flow study
- Cystometry (otherwise known as leak point pressure measurement and pressure-flow study)
- Video urodynamic tests
How do urodynamic tests work?
Depending on the type of test, each urodynamic procedure is different.
- Cystometric tests, or cystometrograms, is a test that uses catheters to measure your bladders pressure.
- Electromyography tests use sensors to measure the electrical activity of the nerves and muscles around and inside the sphincters and the bladder.
- Uroflometry tests are done by having the patient urinate into a machine that measures your flow rate and makes a chart out of the pressure in order to find issues and blockage.
- Postvoid residual measurement is a test that finds the amount of urine still left in your bladder after you have emptied it. This is done with ultrasound equipment.
- Video urodynamic tests combine cystometry, uroflowmetry, and X-ray cystography into one single test to measure urine flow and bladder pressure.
Are there side effects to a urodynamic test?
For a few hours after your test, you may have slight pain while urinating. Due to the catheter, there may even be a slight amount of blood in your urine. These side effects can be eased by staying hydrated and drinking up to eight to 16 ounces every one to two hours. Many doctors will recommend over-the-counter pain medicine and a warm bath, or that you hold a warm washcloth to your urethral opening. Occasionally, a doctor may provide an antibiotic prescription if they suspect an upcoming infection that can be avoided. If you are experiencing a fever, chills, or major pain, contact your doctor or healthcare provider immediately.
