Post-void residual | Radiology Reference Article - Radiopaedia.org

The post-void residual may be formally measured using one of several proposed formulae or (more commonly at the point of care) semi-quantified into abnormally elevated and normal. Using a suprapubic transducer position the urinary bladder is located and centered on the screen; the width and anteroposterior dimensions are traditionally measured with the probe in a transverse orientation.

Age- and gender-specific normal post void residual urine volume in healthy adolescents

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.

Understanding Urine Residual Volumes: What's Normal?

A normal post-void residual urine volume is between 50 mL and 100 mL. A volume of less than 50 mL is considered adequate bladder emptying, while a volume of 200 mL or more is considered abnormal. However, these values can vary depending on individual factors, and healthcare providers may consider different PVR volumes high or abnormal for specific patients.

Bladder Ultrasound and Measurement of Postvoid Residual Volume - urology-textbook.com

The bladder wall should be measured with a filled bladder (greater than 50% of the capacity) on the anterior wall of the bladder. In adults, 7 mm is the upper limit for bladder wall thickness. In children, values above 2.5 mm are pathological and suspicious for subvesical obstruction.

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.
