Principles of the procedure

This procedure is performed to get a better understanding of your bladder symptoms and / or the underlying causes of your urinary incontinence / voiding difficulties.

The test involves placing small pressure and flow sensors into the bladder and rectum (or vagina in women) and assessing how your bladder functions with filling and emptying.

 

Procedure preparation and recovery

You do not need to be fasted for this procedure. It is performed either in the radiology (x-ray) department of the Robina Hospital (video-urodynamics) or in Dr Tracey's rooms (urodynamics) by Dr Tracey and his Continence Nurse (Melissa). Following the procedure you will be able to drive home and continue with your normal daily activities as there is no sedation involved.

The Urodynamics Procedure

On presentation for the urodynamics procedure, you will be asked to change into a hospital gown. A bag / hanger will be provided to place your clothes and other belongings which accompany you into the procedure room.

Two small catheters (tubes) will be introduced into the urethra (into the bladder) and rectum / vagina. These are connected to a monitoring computer. The bladder is then filled with fluid and you will be asked to notify us when you feel changing sensations in the bladder as it fills. With video-urodynamics, x-ray contrast is given with the fluid and pictures are taken as the bladder fills.

Following this, you will be asked to empty your bladder into a commode with the small bladder catheter in place, to measure the flow and bladder pressures with voiding.

The whole process takes between 30-45 minutes, though can be variable from patient to patient.

A formal report is then made for your referring urologist and your follow up will continue with your urologist.

Risks

There is a small risk of urinary tract infection (less than 1%). Your urine will be tested on arrival to minimise this risk.

Dysuria (burning) for 24 hours

Slight blood staining of the urine for 24 hours
