Post-void residual | Radiology Reference Article - Radiopaedia.org
After rotation of the probe marker cephalad to a sagittal plane the infero-superior height is obtained. An estimation of volume (and if performed immediately after micturition, a post-void residual) in milliliters may be calculated as follows 2: estimated bladder volume = 0.75 x (width) x (length) x (height) Differential diagnosis

Bladder Ultrasound and Measurement of Postvoid Residual Volume
The postvoid residual volume is calculated using the formula: Postvoid residual volume (PVR) = length × width × height × 0.5. Various factors ranging from 0.5–0.7 are found in the literature. Depending on the bladder shape, considerable inaccuracy is possible. Usually, there is no residual urine. PVR volumes over 100–ml are considered ...

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).

Purpose of Review Elevated post-void residual volume (ePVR) also known as chronic urinary retention (CUR) is a chronic condition of incomplete bladder emptying in the absence of pain or discomfort. ePVR may be secondary to several etiologies: obstructive, neurogenic, vascular, myogenic, or a combination of these. It can be further divided into symptomatic (e.g., accompanied with lower urinary ...
