Post-Void Residual Urine Test: Levels & Results - Cleveland Clinic
Results of a post-void residual test report the amount of pee left in your bladder, or PVR volume. A normal post-void residual volume is between 50 mL (milliliters) and 100 mL. Your provider might consider different PVR volumes high or abnormal for you. They’ll explain what your results mean.

Bladder Post Void Residual Volume - StatPearls - NCBI Bookshelf
Post-void residual volume (PVR) is the amount of urine retained in the bladder after a voluntary void and functions as a diagnostic tool. A PVR can be used to assess many disease processes, including but not limited to neurogenic bladder, cauda equina syndrome, urinary outlet obstruction, mechanical obstruction, medication-induced urinary retention, postoperative urinary retention, and urinary ...

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.

How Much Urine Is Considered Urinary Retention
A significant amount of urine retention is defined as a post-void residual urine volume exceeding 100 milliliters. This level of retention may indicate serious underlying conditions, such as acute or chronic urinary retention.

Age- and gender-specific normal post void residual urine volume in ...
Elevated post void residual (PVR) is a significant risk factor for urinary tract infections (UTI). It is also a significant predictor of treatment outcomes in cases of vesicoureteral reflux, pediatric enuresis, and non-neurogenic LUT dysfunction. However, the absence of age-specific nomograms for adolescents may limit PVR's use in clinical practice.

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).
