post-void residual urine test

overview

the post-void residual (pvr) urine test measures the amount of urine left in the bladder after urination.

the test is used to help evaluate:

  • incontinence (accidental release of urine) in women and men.
  • urination problems.
  • an enlarged prostate (benign prostatic hyperplasia, or bph).

the amount of leftover (residual) urine can be measured by draining the bladder with a thin flexible tube (catheter) or by using ultrasound.
