If you have a problem with urine leakage or blocked urine flow, Advanced Urology Institute may be able to help. One of the tools we may use to evaluate the cause of your symptoms is urodynamic testing. Some urodynamic tests are relatively simple and can be done in a doctor’s office. Other tests require sophisticated instruments to measure the amount of pressure experienced by the bladder and urethra.
Urodynamic testing is any procedure that looks at how well the bladder, sphincters, and urethra are storing and releasing urine. Most urodynamic tests focus on the bladder’s ability to hold urine and empty steadily and completely. Urodynamic tests can also show whether the bladder is having involuntary contractions that cause urine leakage. Your doctor may recommend urodynamic tests if symptoms suggest problems with the lower urinary tract. Lower urinary tract symptoms (LUTS) include:
- urine leakage
- frequent urination
- painful urination
- sudden, strong urges to urinate
- problems starting a urine stream
- problems emptying the bladder completely
- recurrent urinary tract infections
Urodynamic tests range from simple observation to precise measurements using sophisticated instruments. For simple observation, a health care provider may record the length of time it takes a person to produce a urinary stream, note the volume of urine produced, and record the ability or inability to stop the urine flow in midstream. For precise measurements, imaging equipment takes pictures of the bladder filling and emptying, pressure monitors record the pressures inside the bladder, and sensors record muscle and nerve activity. The health care provider will decide the type of urodynamic test based on the person’s health information, physical exam, and LUTS. The urodynamic test results help diagnose the cause and nature of a lower urinary tract problem.
