Urodynamics

What is Urodynamics?

Urodynamics is a series of tests designed to check the function of a person’s urinary tract. Testing is typically performed to confirm a diagnosis, such as the type of urinary incontinence (uncontrollable urine leakage) a person may have. The tests are most often arranged for men with enlarged prostate glands or women with incontinence who didn’t respond to treatment or require surgery. Test procedures can vary depending on a person’s symptoms and usually include an assessment of urine flow and volume and bladder and urethra function. Tests are conducted by urologists, urogynecologists or pathologists.

When does a person undergo urodynamic testing?

Infection, injury, disease, or age can all contribute to urinary issues. You may be referred for urodynamic testing if you’re experiencing any of the following:

• Difficulty in completely emptying your bladder
• Strain during urination and/or irregular urinal flow
• Painful urination
• Urinary urgency or frequent urination
• Involuntary passage of urine or incontinence
• Feeling pressure even after urination
• Recurring urinary tract infections
• Prostate enlargement

What does Urodynamic Testing consist of?
                                            
Urodynamic testing may involve filling and emptying your bladder several times. Urine volume is commonly measured first (this shows how efficiently the bladder empties) and then checked. What follows may depend on what, if any, issues are detected, but some common tests include:

• Uroflowmetry measures how fast the bladder empties
• A measure of urine passed and the amount that remains in the bladder
• Multichannel cystometry measures the amount of urine the bladder can hold, pressure in the rectum and bladder, contraction of the bladder wall, and urethra strength
• Electomyography checks the nerve impulses of the urethra and rectum muscles, helping determine if muscle or nerve damage exists
• Video urodynamics uses imaging equipment such as x-rays or sound waves records bladder activity

Urodynamic Testing Preparation

There typically isn’t any special preparation required for urodynamic testing. You may have to have either a full or empty bladder at the time of test, and you may be asked to provide a history of your symptoms. Prior to undergoing any medical procedure, it’s essential to inform your doctor of any medications you’re currently taking.

Side Effects of Urodynamics

There aren’t any major side effects associated with urodynamic testing. Patients may feel slight discomfort if a catheter is used during the procedure or a doctor may advise a short course of antibiotics to prevent infection.
