What Is Urodynamics?
How to Prepare for Urodynamics
This study measures your urinary flow rate. You should come to the test feeling as though you need to urinate. Try not to empty your bladder for one hour before your test is scheduled. You will be asked to urinate and empty your bladder into a special commode that allows a computer to measure your urine flow rate and voided volume.
This study measures how well you can control your urethral sphincter (outlet) muscles and helps determine if these muscles are working in coordination with your bladder. "Sticky patches" (electrodes) will be placed near the rectum to record sphincter muscle activity.
This study measures your bladder capacity, evaluates how your bladder holds urine, and determines how well you can control your bladder muscle. One very small catheter will be placed in your bladder, and another catheter will be placed in your rectum. These catheters will measure both the pressure inside your bladder, and the pressure your body exerts on your bladder. You will be asked to report the sensations you feel as your bladder is filled (such as when you first feel the need to urinate and when that feeling intensifies). You may be asked to cough, bear down, or stand during the test so as to check for leakage of urine. At the end of the study, you will be asked to urinate.
Pressure Flow Study
This study measures how well the bladder muscles, urinary sphincter, and the urethra work together. This test may be done sitting on a commode or standing. Your bladder will be filled until you feel that your bladder is completely full. You will then be asked to urinate. The computer will measure the strength of your bladder muscles and sphincter, as well as the urinary flow rate and voided volume.
