This test measures how much urine is in your bladder, and how fast this urine comes out (this is your flow rate). During the test, you’ll pee into a special toilet or funnel that has two parts, a container to collect the urine and a scale.
Postvoid residual measurement
Your Consultant will use this test to measure how much urine is left in your bladder after you pee. If you have between 100ml and 150ml of urine left after peeing, your bladder is not emptying completely.
A cystometric test measures three things, how much urine your bladder can hold, how much pressure is built up in the bladder as it stores urine, and how full the bladder is when you start feeling the urge to pee.
Electromyography places special sensors on the skin near your urethra and rectum or on a urethral/rectal catheter to measure the electrical activity in the nerves and muscles in and near your bladder and sphincters.
A video urodynamic test uses an MRI or x-ray to take pictures of the bladder while it fills and empties. A special dye may be inserted into your bladder using a catheter.
