Urodynamics Study (UDS) What is a Urodynamics Study (UDS)? A urodynamics study is a test performed to obtain more information about your bladder function and urinary tract. It aims to identify the cause(s) of your symptoms to help in further management of your condition. Why do I need this procedure? This test has been recommended to evaluate your urinary symptoms. The information obtained from this procedure helps us to plan appropriate treatments for you. How is the procedure performed? This procedure is performed with local anaesthetic gel applied to your urethra to minimise discomfort. Two small tubes will be placed into the bladder to measure your bladder pressure and fill your bladder with saline. Another small tube will be placed into the rectum to measure your abdominal pressure. These tubes will be connected to a computer to monitor your bladder function during the procedure.

During the procedure, you will be asked to perform a series of activities, such as coughing or straining. You will also be asked to voice out when you have any sensation to pass urine. You will be allowed to pass urine once you experience a strong urge, and the test will be completed. What do I need to prepare before the procedure? • If you have been asked to complete a bladder diary, please complete it and bring it on the day of the procedure. • Oral laxatives will be prescribed to be taken one day before the procedure to help empty your bowels.
