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. A health care provider 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
Most urodynamic tests do not involve special preparations, though some tests may require a person to make a change in fluid intake or to stop taking certain medications. Depending on the test, a person may be instructed to arrive for testing with a full bladder.
