Urodynamics is a study that assesses how well the bladder and urethra are storing and releasing urine. If you have a problem with urine leakage or blocked urine flow, one of the tools your doctor may use to evaluate the cause of your symptoms is urodynamic testing.
Urodynamic tests help your doctor to see how well your bladder and sphincter muscles work. Urodynamic tests can range from simple observation to precise measurement using sophisticated instruments.
A uroflowmeter automatically measures the amount of urine and the flow rate. You may be asked to urinate privately into a toilet that contains a collection device and scale. This equipment creates a graph that shows changes in flow rate from second to second so your doctor can see the peak flow rate and how many seconds it took to get there. Results of this test will be abnormal if the bladder muscle is weak or urine flow is obstructed.
