The procedure is relatively short, ranging from fifteen minutes to an hour in duration. It involves the insertion of one or two catheters into an emptied bladder through the urethra. In the two catheter method, one catheter transfers liquid while the other is a manometer (pressure sensor). In the single catheter method, a specialized catheter performs both functions. An additional rectal catheter may also be placed for additional data. The bladder will then be filled with saline and the patient's awareness of the event will be queried. The patient will often be asked to note when presence of liquid is felt, when the bladder feels full, and when the urgency to void is felt. The patient is then asked to void, and both flow and pressure are recorded. These are plotted against each other to create the<unk> gram.
