What is Video Urodynamics Test?

 A Video Urodynamics is the study of pressure and flow in the lower urinary tract.

The lower urinary tract forms the bladder and the urethra which is just  below the bladder. This is the end point of urine before it leaves your body and is excreted.

 The test shows doctors what will happen to your lower urinary tract when it is filled and emptied with fluid.

 The test is used to determine the pressure inside your bladder and inform the doctor what is happening inside you. Generally the test is not performed if you are on pregnant.

 If you are taking any of the following medications, they will need to be stopped for a time. Contact your GP if you are unsure about which ones to stop taking before the test.

When you arrive at the doctor’s clinic before you start the test you will be asked to empty your bladder and also asked what are your symptoms are and what is happening when you urinate.

The nurse or doctor will then arrange for you to have a tube inserted into your urethra while  you lie down. This tube is called a catheter.

  At the same time a second a smaller catheter is also inserted into the bladder to read the pressure you have inside your bladder.

 As well this ,a very fine catheter is also inserted into your rectum, and also attached to a recording device to measure pressure.

The bladder-filling catheter is connected to a bottle of fluid and the bladder is filled. You will be asked to indicate when you feel the first sensation of wanting to pass urine, and then when you feel you cannot hold on any longer.

The filling catheter is then removed but the pressure-recording catheter stays in the bladder.

 The doctor will ask you to stand and maybe cough  to see if there is leaking when the bladder is full and once that is done the doctor will ask you  to urinate into a special commode type device which measures the flow rate and amount of urine.

 The recording device will measure all of these movements and enable the doctor to determine your bladder pressure and flow rate and then that’s it!This will end the test and all tubes are removed.

 The doctor will then discuss with you the results of the test and advice you about any treatment which might be indicated.
