cystometrogram

Q | what does this test involve?

A | A small rectal catheter is inserted into the back passage. This is essential to measure the pressure within the abdominal cavity, outside the bladder.

A second small catheter is inserted into the bladder after applying a local anaesthetic gel to the urethra. This is essential for measuring the pressure within the bladder itself.

Once the catheters are in place they are attached to a special machine and your bladder is gently filled with water via the bladder catheter.

During this phase you will be asked various questions. These questions relate to how the bladder fills, if there is any leakage or bladder spasm, etc.

On completion of the test you will be asked to empty your bladder and the two tubes will then be removed.
