Urodynamic Study Q&A

What are urodynamic studies (UDS)?

Urodynamic studies, also known as urodynamic tests, include diagnostic testing that helps your urologist pinpoint the cause of bothersome urinary symptoms. They offer an array of in-office tests that provide a thorough understanding of all aspects of the voiding cycle.

UDS allows your provider to diagnose urinary incontinence or other urinary issues in both men and women.

What does UDS measure?

UDS evaluates the ability of your bladder to retain and release urine properly. The studies help your specialists evaluate muscle and nerve function, urine flow rates, pressure near your bladder, and other factors that contribute to abnormal urinary patterns. 

The urologists at Pasadena Urological Medical Group are highly skilled in completing UDS.

Are urodynamic studies right for me?

Your Pasadena Urological Medical Group provider may recommend urodynamic testing if you struggle with:

  • Urinary incontinence or leakage
  • Frequent, sudden urges to urinate
  • Pain or burning with urination
  • Difficulty fully emptying your bladder
  • Problems starting or stopping urination

Any time you experience new or unusual urinary symptoms, see the specialists at Pasadena Urological Medical Group for an evaluation. 

What should I expect during urodynamic studies?

What you can expect during urodynamic studies at Pasadena Urological Medical Group depends on the type of tests you undergo. Your provider might ask that you drink fluids before each test to ensure you have a full bladder.


An electromyogram uses sensors to measure the activity of nerves and muscles in or near your bladder. Electrode patches record electrical currents during pelvic floor muscle contractions.  


During cystometry, your provider inserts a catheter into your urethra to measure the pressure inside the bladder and determine how much urine it holds and how elastic it is. Your specialist also asks you to empty your bladder to measure urine flow rate.


Uroflowmetry measures how quickly you can urinate. You must have a full bladder before completing the test. You then urinate into specialized equipment while a computer measures flow rate to detect possible bladder weakness or blockages.

Video urodynamic studies

During video urodynamic testing, your provider combines uroflowmetry with cystometry and X-rays to measure bladder pressure and urine flow. 

Imaging equipment takes pictures of your bladder as it fills up and empties urine, offering information about urethral and bladder function and structure. You might need a contrast medium to make images appear clearer.

Postvoid measurements

Postvoid tests measure the amount of urine left in your bladder after you urinate. The Pasadena Urological Medical Group may use ultrasound imaging to develop pictures of your bladder and use a catheter to remove excess urine. Postvoid tests evaluate whether your bladder empties properly and completely. 

What happens after undergoing UDS?

After UDS, you may experience some tenderness with urination that lasts a few hours or a tiny amount of blood in your urine. However, these side effects quickly subside. Drink plenty of water after you complete testing.

Your Pasadena Urological Medical Group provider reviews the results of urodynamic studies with you and lets you know if you need treatment, such as medications, lifestyle changes, or medical procedures.
