Understanding Urine Residual Volumes: What's Normal?
The normal post-void residual volume is between 50 mL and 100 mL. However, this can vary depending on individual factors, such as age and gender. For example, in young men and women, a PVR of less than 20-30 mL is considered normal. As men age, prostatic obstruction can occur, leading to a higher acceptable PVR of up to 50 mL.

Postvoid Residual Urine Volume - an overview - ScienceDirect
Postvoid residual measurement assesses the volume of urine in the bladder after voiding and can be performed in the office. One method is to have the patient void and then measure any residual urine by catheterization. Less than 50 mL of residual urine is normal, and 200 mL or greater is abnormal (Nitti and Blaivas, 2007).
