You will start to urinate into the funnel device that is attached to a regular toilet or portable commode. The flowmeter will record information as you are urinating.

Neurogenic bladder dysfunction. This is trouble with bladder function due to a nervous system problem, such as a spinal cord tumor or injury.

The test will be done at this point. Depending on your condition, you may be asked to repeat the test over several days.

A urine flow test may be done on an outpatient basis. This means you will go home the same day. Or it may be done as part of your hospital stay. Procedures may vary depending on your condition and your healthcare provider's practices.

The sphincter muscle is a circular muscle. It closes tightly, like a rubber band, around the bladder opening. This helps keep urine from leaking.

During normal urination, the initial urine stream starts slowly. But it speeds up until the bladder is nearly empty. The urine flow then slows again until the bladder is empty. In people with a urinary tract blockage, this pattern of flow is changed and increases and decreases more slowly. The urine flow test graphs this information, taking into account your gender and age.

You will be taken into the procedure area and told how to use the urine flow test device, called a flowmeter.

A urine flow test is a quick, simple test that gives useful feedback about the health of the lower urinary tract. It's often used to see if there is blockage to normal urine outflow. Health conditions that can change normal urine flow include:

For this test, you will urinate into a special funnel that is connected to a measuring device. The device calculates the amount of urine, rate of flow in seconds, and the length of time until all urine has been passed. This information helps evaluate how well the lower urinary tract is working. It also helps figure out if there is a blockage of normal urine outflow.

You may be told to drink about 4 glasses of water several hours before the test to be sure that your bladder is full. Don't empty your bladder before arriving for the procedure.

Benign prostatic hypertrophy (BPH). This is enlargement of the prostate gland. It's not caused by cancer and often happens in men over age 50. The prostate wraps around the urethra. When it's enlarged, it can narrow the urethra and interfere with normal passage of urine from the bladder. If left untreated, the enlarged prostate can block the urethra completely.

When you are ready to urinate, you will press the flowmeter start button and count for 5 seconds before beginning urination.

Urinary blockage. A urinary tract blockage can happen for many reasons along any part of the urinary tract, from the kidneys to the urethra. It can lead to a urine backup. This can cause infection, scarring, or even kidney failure if untreated.

The bladder is part of the urinary tract. It’s a hollow muscular organ that relaxes and expands to store urine. It then contracts and flattens to empty urine through the tube that carries urine from the bladder out of the body (urethra).

Polarized 3Dprojector

A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low-cost eyeglasses with a polarizing filter for each eye. The left and right filters have different polarizations, so each eye receives only the image with the matching polarization. This is used to produce a three-dimensional effect by projecting the same scene into both eyes, but depicted from slightly different perspectives with different polarizations. Multiple people can view the stereoscopic images at the same time.

Make sure your healthcare provider has a list of all medicines (prescription and over-the-counter), herbs, vitamins, and supplements that you are taking.

A urine flow test calculates the speed of urine flow over time. It may be used to check how the bladder and sphincter are working.

There may be risks depending on your specific health condition. Be sure to discuss any concerns with your healthcare provider before the procedure.
