Urinary conditions can be embarrassing and interfere with daily life. Urodynamics help the providers at Tri-County Health Care identify what the problem is so they can help you can regain functionality.
What is urodynamics?
Urodynamics refers to a series of diagnostic tests that evaluates the function of your bladder and urethra. Your provider might recommend these tests if you have urinary incontinence (leakage of urine), frequent bladder infections, a slow or weak urinary stream, incomplete bladder emptying, or frequent urination. Urodynamics tests provide valuable information to aid in the accurate diagnosis of your urinary problems.
Your provider will help you determine which of the following tests are appropriate for you:
This study measures your urinary flow rate. Try not to empty your bladder one hour before your test is scheduled, and you should arrive feeling as though you need to urinate.
You will be asked to urinate 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 sphincter (outlet) muscles and helps determine if they 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 vagina or 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 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, the 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.
How to prepare for urodynamics
Prior to your appointment, you may be asked to complete a bladder diary or questionnaire. Please bring this with you to the appointment.
Unless otherwise directed by your healthcare provider, you should take your normally scheduled medications. You may eat and drink prior to the study.
The series of tests typically take less than one hour. You will be able to resume all previous activities, including driving, upon completion of the urodynamics studies.
Please arrive for the study with a comfortably full bladder.
