How much water can a kidney hold?

Answer 1

Kidneys do not hold water. Your kidneys are designed to filter your blood and remove impurities. The resulting product of the filtering process is called urine. The urine is then sent to the bladder via the ureters where it is held until you get the urge to void (pee). The amount a bladder can hold varies depending on the person and the size of the bladder. Generally, no more than about 1000cc ( the amount of a 32oz big gulp). Holding your urine, whether on purpose or due to a medial condition beyond this amount is unhealthy, and can back up into the kidneys causing a medical condition called hydronephrosis and/or nephritis ( over-distention of the kidneys, kidney infection).
