Similar to the urinary flow test, this test measures the strength of your stream as you urinate into a funnel. In addition, the patient places a small cuff at the base of his penis before beginning urination. Alternatively, the patient can urinate into a small chamber (see below). As the patient urinates, the machine measures the average pressure of the bladder and the pressure to stop the urine flow. This may be slightly uncomfortable but should not be painful. On a scale of 1-10 where 1 is no urge and 10 is an accident will happen any moment, it is preferable to have an urgency to urinate of 8, 9 or 10. This test is considered a non-invasive form of urodynamics. This means we are able to get excellent information on the function of your bladder and how much the prostate is causing problems WITHOUT the need for invasive catheters. This test also has the advantage of being able to be performed on the same day as your first BPH in person visit if appropriate.
