How much urine does the average adult pass each day?

As mentioned the average adult bladder holds 500 ml (1/2 quart). However, a male can have more as a result of his prostate enlarging post operatively or as a result of a side effect of a new medicine just stated. Nurses can see 1000 ml (1 quart) up to 1500 ml (1 1/2 quarts) emptied into a foley drainage bag just after a urinary indwelling catheter is successfully inserted. If not done by the nurses, the person has to be treated with instruments by a urologist. Bonus Info: Nurses used to clamp shut the bladder drainage mid way for 1/2 hour in the belief that this would prevent “bladder spasms” by the rapidly contracting bladder after catheterization. This has been disproven. Now all urine is allowed to exit as fast as it does.
