What do post-void residual urine test results mean?

ANSWER

If the test shows there’s too much urine left in your bladder after you pee, that can be a sign of a few things:

  • There's an infection in your kidneys, bladder, or the tubes that connect them.
  • Your bladder is blocked at the end so urine can’t flow out.
  • Your bladder has trouble pushing urine out.
  • Your prostate is enlarged.
