What is a Urodynamic Test?
Urodynamics or bladder pressure testing is one of the most important and practical diagnostic tests used to evaluate the function of the lower urinary tract system (bladder and urethra), including bladder nerves and pelvic floor muscles.
For which conditions is a urodynamic test recommended?
- Frequent urination
- Urinary urgency
- Various types of urinary incontinence
- Difficulty urinating
- Burning sensation during urination
- Bedwetting
- Overactive bladder
- Disorders of urinary sphincter or valve function
Preparation Requirements:
- Fasting is not required.
- The patient should not have a urinary tract infection (urine culture test must be negative).
- Arrive with a full bladder.
- Stop medications used for urinary disorders at least 48 hours before the test.
- Avoid heavy and gas-producing foods the night before or on the morning of the test.
- Complete bowel emptying, especially for patients with gastrointestinal problems such as fecal incontinence or constipation. (It is recommended to use a Bisacodyl suppository the night before the test.)
Post-Discharge Instructions:
If fever and chills occur within 72 hours after the test, consult a physician.
Take the prescribed antibiotics correctly and on time.
List of medications that should be discontinued two days before the test:

What are the possible side effects of a urodynamic test?

Burning sensation during urination may be normal for up to 72 hours after the test and usually resolves quickly by drinking enough fluids and soothing beverages.
Blood in the urine may rarely be observed.
