Urodynamics

What are Urodynamics Studies?

Patients who are having trouble with their bladder or symptoms of prolapse are asked to undergo urodynamic studies. These studies enable us to understand how the bladder works, what problems may exist with your bladder function and how any problems may be best fixed.

Who needs to have Urodynamic Studies?

If you suffer from any of the following symptoms you could be referred for urodynamic studies:

  • Urine Incontinence (leakage of urine)
  • Bladder urgency (rushing to the toilet)
  • Going to the toilet too often
  • Difficulty in passing urine
  • Inability to pass urine
  • The need to void twice to empty your bladder
  • If you are about to undergo prolapse surgery

What does urodynamics involve?

  • If possible do not empty your bladder for a few hours prior to the procedure.
  • On arrival you will be asked to change into a gown and void into a special container which measures the amount and flow rate of your urine. 
  • An ultrasound will be done to assess any urine left in your bladder and then a small catheter will be passed to collect a clean specimen of urine.  This will be sent to a pathology group to test for any infection.
  • The next part of the test involves using a thin telescope (cystoscope) to look inside your bladder. Local anaesthetic gel is used on the telescope and there is minimal discomfort.
  • Fine tubes (pressure catheters) are then inserted into your bladder and vagina or occasionally into your back passage. These will be used to calculate pressure changes in your bladder.
  • Your bladder will then be slowly filled with sterile saline and you will be asked to inform us when you have a desire to use your bladder as it fills.
  • Once your bladder is full, you will be asked to cough and, in some instances, to stand and cough.
  • Finally you will be asked to empty your bladder, as before, into the special container which measures the amount and flow rate of your urine.
  • The procedure should take about 30 minutes. 
  • The procedure maybe slightly uncomfortable but you should not feel any pain. 
  • The doctor will be happy to answer any questions you have.

Complications

  • Most people will feel completely normal immediately after the procedure.
  • There may be a small amount of irritation from the catheter that will settle over the next couple of days.
  • Complications following the procedure are very uncommon and extremely rare.
  • However, a urinary infection will require antibiotic treatment.
