How Much Urine Is Considered Urinary Retention
The normal amount of urine retention is typically minimal, with a post-void residual urine volume of less than 50 milliliters considered acceptable. In healthy individuals, the bladder should effectively empty during urination, leaving little to no residual urine.

Age- and gender-specific normal post void residual urine volume in ...
We recommend a repeat PVR and close monitoring if PVR is above the 90th percentile, i.e., PVR >20 ml (7% BV) for males of both the age groups, and PVR >25 ml (9% BV) and PVR >35 ml (>10% BV) for females aged 12–14 and 15–18 years, respectively.

Post-void residual | Radiology Reference Article - Radiopaedia.org
The post-void residual refers to the volume of urine that remains in the urinary bladder after micturating. It may be estimated by visualization using ultrasound or directly measured with urethral catheterization. The use of this measurement is of some utility in several distinct groups of patients, including the following:

Postvoid Residual Urine Volume - an overview - ScienceDirect
Post-void residual (PVR) urine is defined as the amount of urine left in the bladder at the end of micturition. It can be measured by catheterization or non-invasively by ultrasonography. PVR varies in a given individual, hence multiple measurements are often necessary.

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.
