What are Urodynamics and Uroflowmetry?

Uroflowmetry is a test which shows the flow of urine and especially its speed. This helps in determining if there is an obstruction to the flow due to a prostate problem (in older men) or urethral stricture after hypospadias surgery or posterior urethral valves, fluoration etc.

Urodynamics (UDS) is a functional study of the urinary bladder which tells us if the bladder is able to store urine to its expected capacity, at a normal pressure, able to generate sensation to empty at the right times and then empty correctly. This helps in understanding various problems that might be present in the bladder due to neurological or physiological problems causing incontinence, urgency, etc. or post-pregnancy incontinence.

Video urodynamics involves studying the bladder anatomy with x-rays using a contrast material instead of saline. This gives additional information in those whose bladder anatomy is suspected to be abnormal. This is not suitable for pregnant women.

Frequently Asked Questions

Mentioned below are answers to the FAQ's related to Urodynamics and Video-Urodynamics.

Uroflowmetry is a simple test wherein the person/child has to pass urine in a funnel-shaped toilet designed for this purpose. This takes about 5 minutes.

Urodynamics involves passage of catheters (fine tubes) into the urinary bladder and rectum to measure pressures while the bladder is filled with saline and then as it empties. This takes about 1-2 hours for standard urodynamics and longer if video or ambulatory UDS is required.

  2. Bring all reports and doctor’s consultation notes.
  3. Please bring a bladder diary kept for 24 hours before the test
  4. The person/child can eat and drink as normal.
  5. If the person/child suffers from constipation then please take medication for that daily for one week as constipation will interfere with the test
  6. If there is no sensation to pass urine, you may be asked to drink plenty of fluids before the tests.
  7. You may be asked to take antibiotics if you have a history of urinary infections.

The report will be discussed with your doctor and be made available within 48 hours. It can be sent to you by email.

You may need antibiotics if you have a history of urinary infections, please inform us of the same.

Some discomfort in passing urine is possible if you have been catheterised. However, this resolves soon. If it causes stress/pain then you can take a sitz bath in which the lower half of the body is immersed in a warm tub of water for 15 mins.

Although this is rare, sometimes if the results do not match your symptoms or other investigations, we may repeat the test after one or two weeks to get a more accurate reading.
