Gravity? ...Ha ha, no seriously - I had a kidney stone and my urine output decreased. Soon (like 12 hours into it) I felt the pressure in my back and side, even into my gut. The pain is due to the pressure of urine in the kidneys with no place to go, because the kidney stone blocks the little tube from the kidney to the bladder. When that little sucker won't budge on its own under the pressure it's serious. This is just one possible explanation for decreased urine output of course, any other ideas anyone?
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
The detectable trace elements of the drug will drop over time, but unless you stop your intake of fluids, the quantity of your output of urine should not.

IV fluids.
A normal urine output for adults would be about 100ml/hour; beyond 125ml/hour would be considered excessive if it extended for more than 1-2 days.
There are many things that affect an animal's urine output such as food intake. Beverage intake also affects an animal's urine output.
For a male OR female, drinking about 2 liters of fluid a day, the normal urine output should be 800 to 2,000 milliliters a day. Urine output below 500 milliliters a day is considered a low urine output and is a sign of disease.
Decreased urine output is also known as Oliguria. Renal malfunctions or dehydration can cause Oliguria. The ICD-9 code for decreased urine output/oliguria is 788.5.
There are various factors which might decrease urine output. For example, if a person is dehydrated then they will urinate less.
A normal urine output for adults would be about 100ml/hour; beyond 125ml/hour would be considered excessive if it extended for more than 1-2 days.
As blood leaves the vascular system pressure drops, leading to a decrease in perfusion to the kidneys. This causes a decrease in urine production. Put simply fluid is going in to some space in your body instead of leaving through the urine.
You should be aiming for a urine output above 1 ml/kg/hr
