Final answer:
The post-void residual volume (PVR) is the volume of urine that remains in the bladder after urination. In normal adults, a PVR of less than 50 mL is considered within the normal range.
Step-by-step explanation:
The post-void residual volume (PVR) is the volume of urine that remains in the bladder after urination. In normal adults, a PVR of less than 50 mL is considered within the normal range. However, the specific normal range can vary depending on factors such as age and gender. It is important to note that a high PVR may indicate urinary retention or other bladder issues, while a low PVR may suggest incomplete bladder emptying.
