The bladder must be full. Measure the bladder’s Height (AP Measurement) and width in transverse plane Measure the bladder’s length in longitudinal plane Estimated bladder volume = 0.75 x (width) x (length) x (height) Pre Void Bladder Volume Example: AP Measurement: 6.09 cm Width: 8.40 cm Length: 11.45 cm Volume: 306.63 ml Post Void Residual Volume: Determine the amount of urine left in the bladder after urination, known as the post-void residual. A high PVR volume can indicate difficulty in bladder emptying. Normal Results: A small amount of urine left in the bladder after voiding is normal, typically less than 50 ml for adults. The acceptable range can vary based on age and sex. Abnormal Results: A post-void residual volume of more than 100 ml is generally considered abnormal and might require further evaluation or intervention. High volumes may indicate an obstruction, weak bladder muscles, or nerve problems affecting bladder control. Measure the bladder’s Height (AP Measurement) and width in transverse plane Measure the bladder’s length in longitudinal plane Estimated bladder volume = 0.75 x (width) x (length) x (height) Normal PVR Volume Example: AP Measurement: 2.56 cm Width: 3.15 cm Length: 3.18 cm Volume: 13.45 ml ( 50 ml and lower is normal) Abnormal PVR Example: AP Measurement: 48.2mm Width: 98.6mm Length: 46.0 mm Volume: 164ml
