Staff members in the urodynamics lab at Lurie Children’s often perform a test called a uroflowmetry (flow rate), which measures urinating characteristics. It determines the volume of a child's urine and how long it takes to empty the bladder, as well as the force of the urine stream.
In the urodynamics lab, the child urinates as he or she normally would (standing or sitting) into a special commode that is connected to a monitor.
The child should not have a bowel movement or put toilet paper into the commode; it is not a regular toilet.
After the test is complete, the doctor will explain the results.
