What is it?
Urodynamics is a sophisticated method of evaluating how the bladder works. It can evaluate the strength of your bladder muscle, the strength of your urine stream and your pelvic muscles.
Why is it performed?
Urodynamics are performed in both men and women to help guide the physician in your treatment. Typical symptoms that may be reason to perform urodynamics are:
- Urinary leakage when cough, straining, sneezing
- Sudden Urges/Frequent urges to pass urine
- Frequent nighttime urination or leakage
- Difficulty emptying your bladder
- Pain with urination
- Recurrent Infections
- History of previous urologic or pelvic surgery
How to Prepare for the Procedure:
You may take your normal medications and can eat meals on the day of your procedure. Sometimes your physician may give some antibiotics to take before or after your procedure. If you are having any blood in the urine, burning with urination, foul smelling urine or cloudy urine please let your physician know as this might be signs of a urinary infection. They may decide to post pone your procedure until your infection is treated.
How is the procedure performed?
The testing takes approximately 20-40 minutes to complete and is conducted in our specialized urodynamics suite. Wear comfortable clothing as you will be asked to undress completely from the waist down and wear a gown.
- A small catheter is placed into the urethra and bladder.
- An additional catheter is placed in the rectum or vagina in women.
- Small sensors are placed on the groin or buttock area to track the activity of your pelvic muscles.
- The catheters have small sensors on them which are connected to a computer which analyzes your bladder muscle activity
- During the test sterile water is pumped into the bladder through one of the catheters. This mimics what your body normally does with bladder filling. IT IS IMPORTANT TO LET YOUR DOCTOR KNOW WHAT YOU ARE FEELING DURING THE TEST E.G. "FEELING FULL", "URGE TO GO", "CAN’T HOLD IT", PAIN
- You may be asked to cough, strain (as if having a bowel movement), or stand up during the test.
- Once your bladder is full you will be asked to pass your urine into a commode while the sensors remain in place.
What to expect after the procedure:
The procedure has very low risk of infection, bleeding or injury to urethra or bladder. Your physician will likely provide you a single dose of antibiotic to be taken at home after the procedure. You may have some small amount of blood in the urine, or burning with urination after the procedure. This typically subsides within 48 hours. We advise you drink extra fluids after the procedure (about 12 cups over the next 24 hours).
