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).
- Urination problems, including those caused by infections or by problems with nerve signals in the brain.
- 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.
