Urodynamics refers to a series of diagnostic tests used to evaluate urinating disorders. These tests are performed on the bladder, urethra and urinary sphincters. The results of these tests help the patient's physician understand the cause of the problem, where it is located and how it can best be managed.
Causes of Problems with Urination
Problems with urination can be due to a number of things:
- Disease or injury of the nervous system (brain injury, stroke, tumors, multiple sclerosis, spinal cord injury, diabetes, etc.)
- Poor muscle function (bladder muscle, sphincter muscles and other muscles around the urethra)
- Obstruction of the urethra (prostate gland enlargement, stricture of the urethra, etc.)
- Side effects of medication
The comprehensive diagnostic tests are available at TIRR Memorial Hermann to diagnose urinating disorders include:
The sphincter electromyogram is performed to show how well the sphincter (outlet) muscles are functioning and if they are working in coordination with the bladder.
Complex Video Urodynamic Study
This exam is performed with X-rays and allows the physician to monitor and determine how the bladder and urethral sphincter function together.
A cystometrogram helps determine how your bladder and sphincter behave while you store urine and when you pass urine. This test is done for people with urinary incontinence, people who have difficulty with urination, and in people with neurologic diseases that can affect bladder function. This test will measure your bladder capacity and pressure and identify problems such as a small capacity bladder, overactive bladder or high-pressure bladder.
