Urodynamics Department and Continence Promotion Clinic


This department provides a range of services and diagnostic testing for the out-patient and in-patient population with urinary symptoms or incontinence problems such as:

  • Benign Prostatic Hyperplasia BPH ( enlarged prostate gland)
  • Stress urinary incontinence
  • Urge incontinence
  • Overactive bladder (OAB)
  • Neurogenic bladder
Uroflow test and Bladder Scan

This is a simple non-invasive measurement of the bladder capacity and urinary flow rate, followed by measurement of the residual urine by a bladder scanner.

To prepare for this test you need to have a full bladder ie drink 1 pint of water an hour before your test. You will be asked to pass water into a special toilet (which will measure the amount and speed of urine passed).

Urodynamic Studies

This investigation of the lower urinary tract looks at the function of bladder and urethra and takes approximately one hour.

Uroflow test

There is no need to fast for this test, but you need to have a full bladder, so drink one pint of water an hour beforehand.

Filling cystometry

2 fine tubes with special sensors will be placed, one into the bladder and one into the back passage. Your bladder is then filled slowly with water/saline and you will be asked to inform the nurse when you have the first sensation of your bladder filling up.

Voiding cystometry

When you bladder is full you will be asked to empty it before removal of the catheter.

After the test it is important to drink at least one pint of water over the next 12 hours. There is a small risk of urinary tract infection in 1-2% of patients which would need antibiotic treatment. You may notice a small amount of blood in your urine and you may feel some slight discomfort. This should improve within 24 hours. If it persists, please contact your GP or this department.



Our department is in the Outpatients department, behind Clinic C and beside the Diabetic Day Centre.
