WebApr 13, 2024 · Postvoid residual volume (PVR urine volume) is urine that stays in the bladder after voiding. The sensation of not eliminating all the urine in the bladder is real sometimes. Actually, there’s always a small volume left in the bladder, even in healthy people. But if you have a urinary obstruction, this volume is abnormally high (1). WebThe normal PVR is high at birth but approaches adult values by about 6 to 8 weeks after birth. Normal values in children and adults are 1 to 3 units/m 2. Accordingly, the ratios of PVR to SVR range from 1:10 to 1:20. High PVR values increase the risk associated with corrective surgery for many congenital cardiac defects.
