Residual urine refers to the volume of urine that remains in the bladder after a person has completed the act of urination. This concept is important clinically, as the amount of residual urine can provide insight into bladder function and potential pathologies. In healthy individuals, the bladder typically empties almost completely during urination, but various conditions, such as urinary retention or bladder obstruction, can lead to increased amounts of residual urine.

The other options do not correctly define residual urine. The first choice describes urine that has just been expelled during urination, while the second refers to urine that has been produced by the kidneys and is part of the normal renal process. The last option talks about urine collected after a meal, which is unrelated to the concept of residual urine. Understanding residual urine helps in diagnosing and managing urinary tract issues, making it a fundamental concept in urology and medical practice.
