Ob-Gyn questions? Ask a gynecologist online.
Hello, I'm Dr Manos MD, board certified obgyn. A white feathery substance in the urine seen after voiding is not to be concerned about with no other symptoms. The vagina has normal secretions that can mingle with urine when being passed. If my answer isn't satisfactory, you can see a doctor and they can view the urine under microscope.
