What do the urodynamic tests measure?

The most basic purpose of urodynamic tests is to understand the condition of the urinary system, which includes – the bladder, urethra, urine storage, sphincters and presence of infections. 

The test reports give a clear idea about:

  • Nerve and muscle functions are associated with the urinary system.
  • Pressure building within and around the urinary bladder.
  • Urinary flow rates and factors related to urinary discharge.

When does a urologist prescribe urodynamic tests?

  • If there is urine leakage while doing any random activities
  • Following incontinence in urine flow
  • Sudden urges to urinate 
  • Unable to empty a full bladder 
  • Frequent urination (bladder remains full after peeing)
  • Pain urination with a burning sensation
  • Urinary tract infections

What are the primary urodynamic tests?

Urodynamic tests include a combination of tests that are prescribed based on the reported symptoms, such as –


This test helps to understand and measure the leak point pressure. Catheters are used to measure the pressure inside the bladder to know how much urine it can hold. It also determines the elasticity, and pressure flow and detects abnormal contractions.


In this test, electrode patches are placed near the urethra and rectum to record the electrical activity of the muscles and nerves associated with the sphincters and bladder.


You have to have a full bladder to proceed with this test. You need to urinate into special equipment that automatically measures the amount and flow rate. This creates a graph that notifies about any changes and detects blockage.

How can you prepare for a urodynamic test?

Urodynamic tests do not require any particular preparation routine. You might be asked to change certain fluid intake habits or restrictions on certain medications until the test is complete. 

But, these are just for a few hours before the examination. However, few particular tests require you to keep your bladder full before you come for examination. Or, you might be instructed to drink fluid after arriving at the diagnostic centre— Consult with the best urologist in Kolkata prior to the test.

Is it painful? Are there any risks?

The level of discomfort tends to vary from person to person and lasts for a few hours. Some women reported a slight burning sensation after the test, while others didn’t. You may feel discomfort while peeing after the test. 

So, you are advised to stay hydrated, drink enough water, use a warm damp cloth to dab at the urethral opening to get relief and avoid caffeine for the next 24 hours. Often, prophylactic antibiotics are prescribed to avoid the chances of UTIs. 

There is no risk, but if the level of irritation increases, you must consult with the renowned urologist in Kolkata at ILS Hospitals for a follow-up.
