A urodynamic evaluation is an outpatient examination of the urinary tract to diagnose urination disorders. The bladder’s pressure, nerve signals, urine flow rate, and sphincters’ ability are measured through various tests, including X-rays. Patients must arrive with a full bladder and may experience minor pain, discomfort, or light bleeding afterward.
A urodynamic evaluation is an examination of the urinary tract. Evaluation is usually done when a person is having difficulty with their bladder. In most cases, urination problems such as increased frequency, urinary incontinence, and decreased urination can lead to this type of evaluation. A urodynamic evaluation is usually made up of several tests. Typically, testing is done on an outpatient basis, with patients going home immediately following the procedure.
Sometimes, a urodynamic evaluation is called an X-ray exam. This is because X-rays are used to take multiple images of the urinary tract during the testing process. The multiple tests that make up the assessment are usually done in one go. The function of the bladder, as well as the function of the urethra and sphincters, will be studied in various ways. In general, the goal of tests is to diagnose urination disorders so doctors can correct any problems.
During a urodynamic evaluation, the pressure inside the bladder will be measured by filling it with fluid. The nerve signals in the organ are also usually tested. One evaluation commonly measures the rate of urine flow as it exits the bladder. To check for urine leakage, the ability to hold urine can be measured through a urethral pressure test. Special tests are usually done on the sphincters to test their ability to also release and hold urine.
To prepare for tests, people are usually asked to arrive at the testing center with a full bladder. It is important not to urinate before arriving at the testing centre, as your bladder will need to be emptied into a special chair funnel. In the days or several hours leading up to a urodynamic evaluation, the patient may be instructed to stop drinking caffeine. You may also be advised to stop taking specific bladder medications.
Patients usually enter a hospital or outpatient center for evaluation. Once there, he or she will change from her clothes into a hospital gown. As part of the evaluation, catheters are inserted into the bladder, through the urethra. The catheters, which will be connected to a computer, are needed to fill the bladder for testing. After the catheters are in place, patients can be asked several questions and perform certain maneuvers as X-rays are taken during the testing process.
Doctors will inform patients of their results, which may or may not be available immediately following a urodynamic evaluation. Following the tests, most patients are free to go home and resume normal activities. Some people may experience minor pain, discomfort from catheter placement, and light bleeding afterward. There is also a slight risk of infection. If an individual begins to have a fever, feels nauseous, vomits, or is unable to urinate, they should contact a doctor.
